367 ppi enough ?? - Ascend Mate 7 Q&A, Help & Troubleshooting

Hi all, i want to buy this phone but i have one question. Is 367 ppi enough ? Is display sharp enough ? I have read many reviews and test...., in some reviews testers say that the resolution is absolute ok....., in another that is visible difference in sharpness when they compare the screen with higher ppi. What is your opinion ?? I have no chance to see the screen in shop. I want to buy this fone, but i´m worried about this thing. Thanx for answers

The screen is very good, excellent contrast and beatiful colors, for me is ok 367 ppi

Screenshot please...
mine 380dpi..

I find it fine also. Crisp and clear. Easier on the battery.
A screen shot won't help you, lol. Think about that a minute.....

DPI <> PPI. PPI is the physical amount of pixels per inch, DPI is the amount of Dots per inch displayed by the OS.
This phone has a great display. I wouldn't worry about the relatively low PPI compared to newer phones.

I switched from a Samsung with over 440ppi and could barely notice any difference.

I have the Ascend Mate 7 from May and after seven months I am not satisfied.
However, regarding the display I must admit that the difference is unnoticeable with 400ppi or more but the problem is not the dpi. Let's view:
- The screen manufacture
I have a big halo in the center of the screen on white colors (It is getting more annoying).
I have a "light" lightbleed on blacks
I don't think that it's a true IPS because if I look it from different angles the screen colors change, especially the black colors
- The Android UI
We have 367ppi on 6" screen and the huawei stock rom is set to 480ppi, so Android will render the screen as it is a 480ppi display. Big status bar, big everything (but this is up to you, I prefer a small UI). To make matters worse for now is impossible to build a custom ROM that it is not stock-derivative (See my post here).

AMOLED vs LCD vs TFT

So currently these 3 types of display techs(mainly their variants like Super AMOLED, Super Clear LCD, Super IPS LCD, LED Backlit LCD,IPS TFT etc) are the main kinds of display technologies which can be seen on the latest phones.
I have a few doubts regarding this topic.
1- Which technology gives the best color reproduction?
I know AMOLED sucks at this field.What about Super IPS n LED Backlit LCDs n TFTs?
2-Which one has the best viewing angle?
3-What is all this pentile matrix stuff about AMOLED Displays?
4-Longevity,which one lasts long without noticeable degradation?
5-One technologies main advantages/disadvantages over another

1 amoled has very good contrast. but pixel density also important. Phone could have anyone of these displays and have varying dpi
2 IPS has the best viewing angle
3 i heard of that I've have to google it.
4. Longevity has too many variables. depends on use quality and always random dud phones so idk.
5. depends on what you want it for reading vs watching video the size of the screen quality of a product. you can get knockoff iphone with rentina like display doesn't mean cheap phone will last longer then a lessor display. It's more of a personal choice than an overall one better than another.
1. Depends if you're looking for real life looking colors or bright, vibrant colors. Out of the box AMOLED is the latter, while all LCD's are the former. However, all these screens can be adjusted (Android phones anyways), so it's not such a huge issue.
2. IPS LCD has the best viewing angle, but AMOLED is so close behind it's not a deal breaker. All other LCD's would be behind them, but the amount of which depends on the quality of the panel. iPod Touch viewing angle is terrible, while Xperia Play's is amazing for an LCD.
3. Pentile is just a different sub pixel arrangment. It can apply to LCD or AMOLED, it's just seen more on AMOLED's because it makes those displays last longer. Pentile screens don't look quite as crisp as RGB layout screens, but it's harder to notice with the 720p displays out there now.
4. Traditionally AMOLED doesn't last as long as LCD, but it seems to be panel specific. Some AMOLED panels can last really long. All in all you shouldn't see issues within a 3 year phone contract with either.
5. Totally personal preference. I like AMOLED's myself, mainly for the infinite black levels, vibrant colors, and very good viewing angles. Some people like LCD's because the colors out of the box are more natural. Also some like how there are 720p RGB layout LCD's on phones. AMOLED hasn't been able to do this yet, it has to resort to pentile for those resolutions. Then again, it's hard to notice at ~320 PPI

Personally i seem to prefer SLCD over SAMOLED, the whites are bluish and there's a weird hue in all colors except black in amoled, not sure why but the blacks are true blacks which is not the case in lcd where all colors are perfect except black is kind of grayish because of the back light.

My AMOLED colors were slightly off when I got my phone (a little on the warm side). With a quick color tweak the colors look amazing now, along with the true blacks.

Super Amoled Plus and super LCD are the higher end panels and bring out the best of each technology. However nothing beats a good ips panel in my books. The colors are flawless, and the viewing angles impeccable. That is all I need.

AMOLEDs provide true black because in this technology, each pixels produce its own light(unlike LCDs,in which a single lightsource illuminates the entire screen). And when black is needed to be produced,that individual pixel is completely shut down,thus zero light is emitted.Hence true black.

Technically IPS is a really good TFT panel. Like how a maybach and a c200 are both Mercedes. IPS being the maybach ofcourse.
And technically an LCD is also tft. But then it starts getting confusing if you go down that road.

amoled is much more colourful than the others.
A I-Phone 4 looks really pale beside a Galaxy S or a Galaxy S2.
Amoled has limited life-time and looses brightness.
The power consumption is dependent extremly on the brightness of the colour.

Power consumption is EXACTLY what interests me most about this. I remember reading a couple of years ago that Sony Walkmans using OLEDs offered vibrant colours while using far less power than LCDs. The trouble is I'm having trouble finding more information on this now that I'm looking at OLEDs in smartphones. Is this true, does OLED use less power, does it not use a backlight like LCD?
I'm dying to know because I bought a cool phone a few months ago, but hadn't learned about battery usage/capacity and now I HATE the phone for it. I'm looking at the OLEDs e.g. on the Motorola RAZRs (with 2000 mAh batteries) and I'm curious about them.
UPDATE: I just found a simple document composed from companies and organisations involved in OLED production which, they say is designed to eradicte myths on this. You can see the document here, and on power consumption, my brief understanding is this:
LCD: uses maximum power to display any image
OLED: uses minimal power on darker images, maximum power on brighter/whiter/colourful images - white/very bright images use more power than LCDs
This leads me to think that switching to OLED can only result in at least some benefit in battery life, no? I think most of us on Android are conscious of the use of black and white in the UI, wallpapers etc. so something like this would help. Is it a significant benefit? A backlight on a TV plugged into the wall is fine, on a smartphone I can see why it's a battery-killer. I note the caveat about OLEDs using more power for white and very bright images, but the way I see it, unless you're using a white wallpaper, this isn't an issue. I speculate a power saving when all is accounted for.

So, if a TFT display is considered not quite as good as an AMOLED or an SLDC…how could a difference be noticed between the Xperia Z’s TFT display, the SGS4’s AMOLED and the HTC Butterfly’s SLDC3 – all 5 inches, all 1920x1080? Battery life/colour reproduction/daylight visibility?
Thanks for the input.

I'm sorry for breakin' in this late, but... I hope to help in the future decisions.
We're mixing some things here:
LCD is a technology. AMOLED is another technology.
TFT is a sub technology that must be applied under one of the mentioned before.
TFT is an array used to feed large displays (a mobile phone is already a large display).
Since phone displays are "large" either LCD or AMOLED need an active controller to maintain brightness in each pixel.
This is A BIG difference between OLED (PMOLED) and AMOLED.
As SharpnShiny mentioned mp3 players/walkmans (small displays) can use OLED which use much lesser power than AMOLED.
In OLED/AMOLED displays each pixel produces it's own light, which can be a good power saving if most of the image is black or dark, because, in black the pixel just doesn't light up.
In LCD there's permanently (monitor ON) a "backlight". Even if the image is black! What the display does is block the backlight when it needs black.
About power consumption in either cases... I don't think there's a really noticeable difference because it depends a lot on the usage!
UPDATE: Sometimes the best way to save battery is to tweak several settings (including the Kernel) as the display brightness levels and thresholds.

Thanks! That's what I intend to say. It seems many people misunderstanding about TFT.
TFT is not a panel technology in comparison with TN, MVA, IPS, PLS, AVS, AMOLED,....

In other hand, Led-backlit is a similar case, it is a type of backlight, cause the LCD need the illumination. And there are 2 kind of LED, Edge and full-array. In mobile, almost is edge-led because of low cost and thickness. Full-array Led backlit only appear in several high-end TV models. The older tech is CCFL, which consumes more power
It means that a new LCD display which uses IPS panel also include a TFT layer and an edgeLed-backlit.
Sorry if any typo mistake. My bad English
Does anyone here know much about SAMOLED? I read in a phone review that it's more a marketing term than actual performance difference over AMOLED, but I'd prefer to double check that. For anyone who hasn't seen that term, the S is for Super (don't laugh yet!). I think the Motorola RAZR i and the Samsung Galaxy S III Mini are using SAMOLEDs.
I've been comparing my new and old phone screens when considering this thread. I have to say I prefer the TFT LCD screen more than anything. Even with a lower resolution, the images (video and static) is beautiful to me. My RAZR i has a higher resolution but a pentile matrix SAMOLED. It reminds me of phones 5 years ago, the matrix gives the impression of cheap pixel displays in my opinion - but I keep reading it's amongst the most battery-saving screens in the mainstream smartphone market and for that I am greatful.
I get noticeable battery drain difference by turning down the brightness on my AMOLED screen.
Decreased brightness also extends the life of the display.

Yes. SAMOLED is the Super AMOLED from Samsung.
I wouldn't dare to say that it's just a marketing stuff... Because it's a little about "sub-pixels" and their layout. I would say thay the AMOLED technology is there with Samsung's engineering so that picture could get better.

That's what I meant in my last post, under the UPDATE statement. Also try to tweak your phone's clock (if you haven't done it yet).
Mine (a poor 600MHz ZTE Blade) is working from 245MHz to about 650MHz depending on the load (from underclock to overclock).

Do you like the One S display?

I just want to know if you satisfied with the One S pentile matrix screen. I have a Sam S2 and recently bought a One S (S3 chipset) and i noticed the lcd is very pixelated (if its a real word, sry for my English) compared with the S2's screen. Its not too bad but noticeable and a bit disappointing. How you live with this?

By not being incredibly picky. The phone wasn't cheap, so before I signed a contract, I made sure I was happy with every aspect of the phone. While I do agree it's pixelated, and that my Sensation had slightly better quality, I am incredibly happy with the screen. I'm rarely centimeters away from the screen so I can live with it especially because the color reproduction is amazing.

I think you just get used to it after a while. I couldn't stand the screen when I first got the phone, It stopped me using it regularly because I just used to get annoyed at the screen! (sad I know) But now I don't even think about the screen because I'm so used to it. I came from the Desire S which had a S-LCD display and a 480x800 display so that was a very good screen considering it was only 3.7 inches! I found the amoled colours of the one s to be extremely saturated. I didn't like the yellowish/blueish whites and the fact that every time you slightly changed the angle of the screen the colours would turn slightly blue. Text looked pixelated especially on a white background, that doesn't help considering a key part of sense 4 settings is all white background. It took me a good month to get used to the screen and 3 months in, I'm used to it Possibly getting the Nexus 4 soon so doubt I'll have much longer with this phone anyway.
Sorry for the little off topic might pickup a one s didn't want to start a new thread...
I saw the one s at my local fido store and damn its so snappy even whit sense !! But i tried the one x and it was somewhat slower is this normal ? Flicking through homescreens just werent the same..

I did notice it some when I first got it, but I really don't anymore at all, and like was said above, I'm never close enough to my display to really notice it. I think the screen is incredible, as is every other aspect of the phone. I LOVE my One S.
I thought it would annoy me, but the phone was free so I decided to bite the bullet. I've had the phone 6 months now, and I really don't notice it at this point.
I love the one S display, sure the screen isn't as sharp as the GN, GS 3 and one X etc. and you don't get as much screen real estate but everything else is just as good, if not better:
- one of the best screens in sun light, don't even have to put my screen above 70% brightness in direct sun light in order to be able to make stuff out easily and this is on a darkish background too, MUCH better than the GN and GS 2 in this area
- colour reproduction is superb, my screen is pretty much perfect, whites are super white, brighter white than my dell u2311h, iirc a review site stated that the screen is better calibrated than the GS 3 SAMOLED screen
- no tinting at all on mine, usually with AMOLED screens you get a blue or yellow tint, which is noticeable at angles on whites but not on mine (this varies with every single screen though)
- of course blacks are black and the viewing angles are superb
- high contrast ratio etc. so games and videos look great
I only notice the pentile when looking at white text on black backgrounds and a few icons, but only when I really look for it and have my face pretty close to the screen. I find the one S screen to be sharper overall compared to the GS 2 screen.
I have had the one S beside the GS 2, GN and GS 3 and personally I didn't like the GS 2 screen at all, res. is too low so things are huge (felt like an old man using a phone designed for people with poor eye sight ), colours are far too saturated/warm. The GN screen is nice and sharp but the colours aren't saturated enough, rather dull over all and plus both phones are poor in comparison to the S for view ability in the sunshine. The GS 3 screen is great, better than the GN, however, I think the one S screen looks better for colours.
Anandtech more or less summed up my thoughts:
What’s different, however, is how well HTC has controlled the color temperature and gamma compared to Motorola in the RAZR. As shown in the HCFR galleries below, gamma is pretty close to 2.2 until you get to the high end, and color temperature is pretty close to 6500K, except at the two darkest grey points. This is so much better than any other OEM calibration of an AMOLED panel I’ve taken a look at, which is rather humorous because the panel is undoubtably Samsung’s. HTC is also letting the panel go pretty bright, up past 350 nits, instead of clamping it way down around 200 (I’m looking at you, Galaxy Nexus) to save power. I also haven’t noticed blacks not being totally off on the One S like I have with some others. Of course, colors are still massively oversaturated if your source color space is sRGB.
I’ve griped about PenTile RGBG before on this panel and other SAMOLED displays, but I find the One S to be completely enjoyable in spite of having it thanks to two things. First, how well HTC has controlled the panel (no awful hues, weird white points, or dramatic shifts as you change brightness) - this is basically the best I’ve seen this particular panel, and until SGS3, the best I’ve seen AMOLED in general. Second, because HTC doesn’t appear to be applying any processing that applies sharpening (like Samsung’s mDNIe) to text.
How you feel about PenTile really is the final factor: it’s there, but I’ve slowly become accustomed to it after staring at it for so long. If you go back to the Nexus S days, I was one of the most outspoken critics because of how large those subpixels were. With small enough subpixels (below visual acuity), PenTile starts to make sense. In other news, HTC moving back to Samsung AMOLED for phones is an interesting move after supply issues forced HTC to SLCD with some earlier phones, here on the HTC One S however, it looks great.

My solution: Get old. You probably can't see all the minute issues you guys think matter, and you don't really care if you do. Every phone I've ever had has had a better screen than the previous and I think that's pretty nice.
I hate the screen, drives me nuts. I found that using a theme that mostly uses blacks and whites makes it more bearable though.

Have to agree. Thing is apart from the screen it's a fantastic phone. It's so fast, battery life is great and the camera is great. I don't even think the screen would be that bad if it wasn't pentile it's just the fact that it's a pentile display it makes the phone look way more pixelated than it should be
I think I need to go to specsavers, I've never noticed a problem with the screen.
The screen on this is amazing. Don't notice any pixellation whilst on it . It's quite an improvement over my old Wildfires QVGA 3.5 inch 240x320 TFT display.
Sent from my HTC One S using Tapatalk 2
If you switched from Wildfire you cant see this but if you had any phone in the alike pixel density and resolution you can see the difference. According to others opinion its not bad, the perfect color saturation, contrast etc will eliminate the bad feeling about those subpixels.
HTC does calibrate their screens nicely
I suppose it depends on what you're used to. When you come from an iPhone or high-end LCD-screen you probably will get annoyed with this display. However, when this is your first touchscreen smartphone or when you had a smartphone with a low-end display before this one, you will probably be able to cope with the slight pixilation.
Personally, even with this being my first touchscreen smartphone and coming from an E72 with a PPI of about 170, the display of this device would be the only reason for me to buy a One X or Nexus 4. That being said; you don't buy a smartphone solely for its display, you buy it for the complete package (price, battery, design, display, size, cpu/gpu, storage, support, OS, cloud integration etc.). And for me, the package the One S offers is more compelling than that of most other smartphones one the market.
I compared the One S screen to that of my Galaxy Nexus and honestly, when it comes to clarity, there isn't much of a difference. If you are in your twenties with near perfect eyesight and able to hold the phone less than a foot from your face then you will probably see pixelation but at normal distances it isn't an issue. For me it seems that anything above 250ppi is fine - my original Galaxy S was less (I think 233ppi) and that display was pixelated to me, but then again it was an earlier generation screen, I'm sure there have been other refinements besides resolution since then.
One S 256 PPI
Sam Galaxy S2 217 PPI but looks sharper.
Its all about the pixel placement, pentile matrix is a pattern. This matrix gives us better colors because more subpixels. Google for it there are many info i cant explain it in english
I come from an LG Optimus 2x, 4'' ips display, 800x480, and I feel this display better IMHO.

I said Galaxy S, not S2.
Yes the S2 was/is superior despite the lower resolution thanks to the RGB arrangement (not pentile). The original Galaxy S was pentile, and not that great by today's standards.
It's okay, but I'm actually kind of unsatisfied with the blacks. I thought it would be completely black, but when I have a black picture shown on the phone in a completely dark room, the screen still lights up

[Q] Screen Resolutions???

hi everyone
I need to ask something that i was unable to find answer on internet or Google searching. I come straight to the point. It's basically a general thing about devices that i found different in aspect of screen resolution and i couldn't find difference.
There is one Android device which gives resolution of 540*960 on a 5inch LCD and there is an Android phone which gives 1080*1920 resolution on 5.1 inch LCD like S5 AND 1440*2560 resolution on 5.1 inch LCD.
I want to ask what is the difference that these resolution gives, i am currently using 540*960 resolution phone and what difference i would note by using 1080*1920 resolution? will thing appear small on it?
For example on a home screen, i have a gadget of weather, will it appear more smaller? because i didn't get the difference of resolution and their result difference.

470*320and below IS mdpi - normal- 3 to 4.2 inches - packed with upto 200ppi
640*480and up IS hdpi- large-4.2 to 7 inches - packed with 200 to 300ppi
920x720and up IS qhdpi- extra large- more than 7 inches - packed with >300ppi
if that's unclear to you

i am sorry if i sounded noob but i was unaware of these things. I was just wondering what's the difference of resolutions when the screen size is same.
From your post what i got was, that it is basically the PPI thing, which makes screen more bright and colorful etc. so more PPI is based on more resolution or pixels.
I am currently using Huawei G610s and it has 640*480 with 220ppi. I thought that resolution is same as in case of computers, the more resolution the more smaller the pixel and picture size and more desktop area. I am currently using 1680*1050. So i thought in same context and was wondering and thought to ask.

From your post what i got was, that it is basically the PPI thing, which makes screen more bright and colorful etc. so more PPI is based on more resolution or pixels.
I am currently using Huawei G610s and it has 640*480 with 220ppi. I thought that resolution is same as in case of computers, the more resolution the more smaller the pixel and picture size and more desktop area. I am currently using 1680*1050. So i thought in same context and was wondering and thought to ask.

firstly ppi refers to the pixels per inch
it in simple words is how tightly pixels are packed in a sq inch of area on the screen . the more the ppi count the smaller each pixel gets providing you with sharper and intense quality display
also if you did not search api guidelines on google

here go ahead and just go through the detailed version and i think it will solve almost all of your query

Now. Don't get concerned on how you sound. We were all like that at some point. The resolution that you have probably is around 200 DPI (depending on screen size) My phone (Xperia SP) has a 4.6 inch 1024 x 720 display AKA 720p display. In person, how they look actually matters. Anything above 300ppi is crisp and extremely sharp. A Samsung galaxy s5 has a PPI of around 400. These numbers don't really matter but if you see them in person, they really look nice. Hope I helped you.

Is the OLED using Pentile or RGB subpixel?

Does anyone know? There is a big difference especially if the screen is bigger and the resolution is not quad HD. If you do not know how to tell them apart, just google pentile vs rgb

EDIT: Answer found, Pentile display for Honor Note 10
Debatable. This is a big screen phone not the typical 5.5 inch ones back in the day. I still want to know if this is rgb or not. I have a mi max 3 and the screen is pretty good
It is almost sure pen tile. As I know, only tab s and tab s2 hase pure rgb matrix... I had and have both tabs. And had at least 15 different phones, also flagships between them,wirh pentile
Picture quality is night and day... You can never get that accuracy of colors in pen tile.

Everyone knows that from the spec sheet. I'm talking about the subpixel arrangement. RGB vs pentile diamond layout. It makes a difference on a big display

Before I made this thread I did that, no answer can be found. I'm trusting the owners of this phone on this site to help find the answer.
Answer found. Pentile display said by Frankie Tech. He says it in his video around the 8:17 mark. He said Honor 8X LCD is sharper than Honor Note 10
Hi,
Me, I have the device for a few hours, and I must say that I find the display really good.
I even tried to downgrade it to lower resolution and it still looks good with no real difference in sharpness. Now, I am almost 50 years old and so maybe my eyes are fooling me... so don't trust this too much. But I'm pretty sure that for "daily use" it is more the enough.
There's one thing that bothers me though : it is that slightly blueish tint it's getting when viewed at about 20°C vision angle. Not as bad as on earlier LG displays, but still there. Noticeable only on white backgrounds It's common "disease" for OLED/AMOLED displays.
Anyways, how can I say it's pentile or RGB ? The link provided explains the difference but doesn't say how to check does it ?
Regards.

It's easy to tell by experience at looking at screens especially on a big screen even on a 5.5 inch screen I can tell the difference/ Oneplus owners have complained about their displays being not as sharp too because they use 1080p pentile displays now imagine this on an even bigger screen like the Honor Note10, 8X and 20X.
The one method to use is to drop bits of water on a screen displaying text and use a magnifying glass then you can examine the subpixel arrangement to determine if it's pentile or rgb. Smaller drops of water magnify the pixel more and largers drops magnify less
This is example is a RG/BW LCD which is also blurry. Notice how this display has the blue in a diamond pattern similar to a Pentile layout. This makes text and edges of icons and pictures and finer detail look blurry.

A traditional RGB LCD has all the colors in a straight line

I'm fine with pentile on a 2560x1440 or higher display but not on anything lower as it's noticeable
These are pictures of my mi max 3 6.9 inch lcd display. Rgb layout, red blue green all in a straight vertical line. One of the reasons why I picked the max 3 over the note 10 was the display sharpness and accurate color reproduction.

Amoled or OLED screens are overrated, Poco-f1 screen doesn't lag behind in any circumstances.:cool
Yeah, but it drains more power even with an all black setup.

Lo. I wonder if you have ever used a Samsung device with sAMOLED display? Just place both a sAMOLED and a LCD display side by side and see the difference.

Previous phone was Galaxy S8, I don't find much of the experience difference.
IPS LCD and AMOLED displays has advantages and disadvantages
IPS LCD has that AMOLED doesn't have:
-Sharpness and Clarity is good
-Natural Colors (AMOLED is little saturated on Colors)
-Can recover to accidental burns or screen burns (AMOLED cannot recover on screen burns thus leaving white marks)
-Longer pixel life (AMOLED's pixel quality degrades over time)
AMOLED has that IPS LCD doesn't have:
-Improve battery life as turning off pixels without backlight (Good for Dark Themed apps, videos, photos)
-Brightness and Contrast is good
-Good Viewing angles
-Always-on Display (IPS LCD cannot support this due that it uses backlight rather than turning off black pixels thus increasing power consumption)
Verdict:
No clear winner. It is the preference of both users and the manufacturer on what type of display they want to use. This is why Xiaomi uses IPS LCD Displays because it is cheaper than AMOLED ones. The target is being a budget flagship-tier phone thus achieving it.

Yeah best done with a gray picture so you can see the burn in on the oled. After some burned oled I only buy IPS screens.
I can't understand the "true black" hype as there is no such thing in real life and as the brain even can interpret white as black if the contrast is right.
As long as OLED tends to burn in, it's a no-go for me.

Three reasons why Xiaomi should go the OLED route :
True black :
Here's an example of true black :
On you Poco, go to full screen settings and turn off the notch. Now to two top corners are rounded as the bottom ones. Now go to a dark room, as if you were using your phone at night. Well you still see the top corners of your phone's screen on. Of course that color is black, but it's awful. (In a dark room you see it better, but I see it in the sun as well).
Always-On-Display or AOD :
You can't have AOD on an ips panel. End of the story.
Brightness :
Outside in full daylight, I constantly have to block sunlight off the screen and put it right up to my face to see what's on it. OLED is way brighter.
Bonus :
Dark mode is here in the MIUI beta and coming to everyone later. MIUI 11 will have it out of the box. This means phones with OLED screens will have a great battery advantage over ips.
Also - OLED and AMOLED tend to use very low PWM which may give you a headache/migraine.
For instance - Xiaomi Mi 8 with AMOLED panel has backlight that flickers at 100 Hz, Samsung S9+ has AMOLED panel with backlight that flickers at 215.5 Hz while Pocophone has a backlight that flickers at 2315 Hz (source - notebookcheck reviews)

They have pros and cons, both of them. While sAMOLED has better contrast, black colour, and often better viewing angles, IPS has most of the time better colour accuracy and it's better to look at while exposed to direct sunlight. I mean, you use the one which suits you the best. Unfortunately, Xiaomi uses probably some cheat IPS panels, so they look worse compared to some higher end phone with IPS panels.
True black is just an excuse ??
And amoled panels aren't bad or anything. They are just over rated and people say. Amoled- amoled l. Look it's not that a big of a deal.
And battery consumption difference is just minor
Like 3 or 4% through dark mode in amoleds too
So what's the hype
I just said Poco-f1 LCD panel is just as good as OLED
If not it's only a difference of 19-20
Nothing more
Ill always prefer lcd. When i bought the phone i had to keep it on over night for data transfer via wifi as i had no pc , to keep the wifi transfer app alive i had to keep screen timeout to never, on morning i noticed lcd retention all over the screen ?(similar to amoled burn in but not permanent), had it been an amoled surely my screen would have to be replaced day 2 of buying a new phone. I had to use the phone screen a lot but the Lcd retention went away completely after around 8 hrs:victory:, so no amoled ever unless they fix burn in!
lol this thread is like a circlejerk. my poco f1 has crappier display than my a2. it has the lowest quality lcd possible. this comes from someone who has used over 37 android smartphones throughout this decade with many being top tier flagships.
But poco F1 has a comparatively dim display even for an LCD. Under heavy sunlight it becomes difficult to see the display. On S10 for example you can clearly see it in any condition. That is why they bumped up the brightness in the poco X2
