i bought a touchscreen kit for me EEE netbook but they sent me 2 by mistake a 7" and a 8.9" kit. I used the 8.9" for my EEE netbook and still have a spare 7" kit.
The kit uses a USB connection so i needed drivers, when I looked in the driver disc i noticed that it has XP and Vista drivers along with a WIN CE driver and was wondering if there was anyway to hook this up to my Fuze...
I have a 7" dvd player/radio with TV input in the dash of my car I was wondering if it would be possible to add the 7" touchscreen kit to my dvd player screen and somehow get touchscreen to control the fuze,
The next problem would be getting the resolution of TV out to change
The Fuze outputs at 640x480 4:3 aspect ratio but my TV screen is 16:9 aspect ratio.
The Touch Pro 2 uses almost identical hardware but is able to output 800x480 almost 16:9 aspect ratio so it must be possible to output at that resolution...
If I could get both of these working I can save some money and abandon my Car PC project...
it require usbHost to use usb devices on a pda
something which very few htc pdas support
raphael being one of them lacking as far as I know

This might work, but I cannot confirm: http://www.nyditot.com/NVDPage.asp
I've tried it on my old Dell Axim x5 and Mymobiler recognized the larger resolution, but applications were slower.
i have a weird question.
assuming i know perfectly how to change and replace the phone's screen and price isn't a factor, is there a way to get same ratio and resolution 4.3" regular RGB instead of the pentile for the one s, and connect it to the phone?

Long answer: Dont think such a display exists, i mean sure for other phones maybe but many things would have to match even if you disregard physical size and shape, like connectors and assorted chippery. You would want an SAMOLED+ I guess since most of the time whether the digitizer is integrated in the display or front glass differs between AMOLEDs and LCDs thus you need AMOLED to make it work and SAMOLED+ specifically to get RGB subpixel layout. Dont know of a phone with a 4.3" SAMOLED+...
Short answer: Sadly no, learn to love the AMOLED
Literal answer: Sure if price is not a factor then have one made for you by Samsung/LG/Sharp
Anecdotal evidence: The Desire was first made with a Samsung AMOLED panel, then they switched to a Sony LCD panel because of AMOLED shortages. The displays had different connectors and IIRC correctly from when replacing my AMOLED the LCD one would not have fit. Check Ebay for pictures of both... and this was before they started integrating the digitizer in AMOLEDs so one less thing to worry about even.
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).
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
So this is probably the worst display I have seen in a phone in years.
Little back story here. Right now I have 2 phones, one is up for sale on Swappa (OnePlus 9 Pro) which is a long story on why I'm selling it, and my temporary daily driver is a Motorola Power 2021. I got Moto because the 9Pro was unusable at the time and I needed something quick and cheap to hold me over until I figured out a long-term solution. Yea, 1st world issues here. lol
Well, once I fired up the Moto Power, I absolutely loved it but it just wasn't powerful enough and I knew I needed a bit more memory and a slightly faster CPU. So when the Edge was announced, I thought, well hell, I'll sell the 9Pro and grab an Edge. This would leave my Power as a backup to me and my family.
Anyway, I unboxed the Edge, powered it one and began the setup. About 30 seconds into the setup I realized the display is worse than the $200 Power. Heh. Screw this I'm returning the phone.
So what's wrong with the display? First of all the off-axis is horrid. Anything over 20 degrees, it dims out and the colors shift. On-axis, I see nothing but a halo effect that was the norm of LCD displays from 2010, like the OG droid, which gave me a headache.
I really wanted to like this phone, and I think I would have if it wasn't for the display. I didn't get a chance to mess with it before purchase, so there is that. I wouldn't have bought it if I had hands-on with it first.
So not sure where I'm going from here. I guess unlist my 9pro and deal with it's issues until they fix their crappy firmware or maybe a Pixel 5a, but I'm old and need a larger display. Maybe another Moto like the the G Stylus or the Edge 2020. I just know I will be window shopping next time.
I just wanted to share my experience. I hope everyone enjoys this device, it's just not for me.
Cheers!
Thanks for your input. That's what was worrying me, was the display. I think I'll look else where.
If anyone has any specific questions regarding the display, or anything where it doesn't require inserting a SIM, let me know. I'm still waiting to get confirmation from Motorola about returning the device, so I have time to do testing for those who are curious.
I have one question for anyone out there that can answer, as I'm not very knowledgeable on display technologies that aren't AMOLED...
The comparison chart on Motorola's website show the following for display technologies:
Motorola Edge (2021) - LCD, 8-bit, 144Hz refresh rate, Up to 576Hz touch latency
The Cheap Moto G Power (2021) - Simply says: IPS
and then the two phones I'm interested in, the Stylus and the One 5G Ace both indicate LTPS displays.
Okay so I know that the LCD display the Edge has; my eyes are not fond of.
The Moto G Power has IPS, I feel is quite nice. It's not AMOLED, and when turned sideways while wearing polarized glasses, of course turns the display black.
What's up with LTPS??! I've never heard of this technology before. Is this better or worse than LCD and or IPS?
Thanks!
Liking mine
Screen is IPS and the viewing angle is like One Ace
144Hz rate doesn't have much benefit due to LCD/IPS response time
Set to automatic is the best bet

LTPS is Low-Temperature PolySilicon. A substrate the LCD is manufactured onto. It is still an IPS LCD screen, just manufactured using a different process that also has the benefit of making it easier to create LCDs with a higher pixel density. It also improves the display's power consumption over older IPS LCDs.
The screen on my Edge 2021 is just like the screen on my previous phones that use IPS LCDs, be it LTPS or not. If the Edge screen bothers you but other IPS LCD displays do not, then I think it's your device that is the problem and not the technology itself.
I'm extremely flicker sensitive and avoid using AMOLED screens. The Edge's screen is nice for me to look at.
