I think most of us with Nexus One's have discovered or read about the display's PenTile pixel setup. I am frustrated, because I look at a Droid, and the resolution seems so much better. But maybe, hopefully something can be done about this.
My main question is: How would one go about tweaking/changing the Pentile display driver hardware?
Supposedly, you can eliminate color fringing by tweaking certain register values in the display drivers and reducing the amplitude of modulation. It sounds like you basically need to stop the locally adaptive filter detector.
This article describes the whole issue:
ww.metalev.org/2010/03/more-on-resolution-of-nexus-one-display.html
Have any of the developers out there discovered tweaks and/or fixes for this dilemma? Is anyone like cyanogen working on improving the nexus' resolution?
there's nothing wrong with PenTile or it's register settings
Visit the Nouvoyance website and look for technology white papers on the PenTile OLED displays
The above link will explain that the resolution is fully supported. Hutinson simply found a "hack" to make the SPR engine give slight colors when excersized in a very unusual pattern.
hmmmm
Despite the claimed resolution, the screen does not look a good as the 3 subpixel screens. Nouvoyance claims it should look the same, but I just don't see it and I want a solution. I will start reading those white papers at nouvoyance. Thanks man
I just want to clarify the question in my mind. Is the Super AMOLED have a expired date? Someone say that the SAMOLED have a 5years Life, and he said that he work at Samsung PH but I wondering why he is not in uniform that day.
It is true or not?
Sorry for annoying question.
i think it's absolutly not true
I know that early OLEDs had a life span, and that developers where working to fix that. No idea if they ever did.
Every display (LED,AMOLED,LCD,PLASMA) has a "life span", which is the time after which they are only half as bright as in the beginning.
It is true that earlier AMOLED display had a shorter lifespan than common LCD displays, i don't know the lifespan of our current AMOLED display generation though.
I think you can only estimate this, even the different subpixel (green,red,blue) fade at different speed.
This is nothing that should worry you as its perfectly normal for all display types.
I have two screen on my desk, one is older than the other and though they are the exact same model, the colours are different .
If you want you can read up a bit @ http://en.wikipedia.org/wiki/Organic_LED
I’m going to be buying a new phone soon. I’ve been eyeing up the Galaxy S II but I thought I might as well wait and see what is announced this month. One thing that all top end rumoured phones have in common is a 720p display. I have to admit this alone has tempted me to wait. But then I got to thinking, aside from the ‘cool’ factor. What benefit in the real world will a 720p display bring us?
The two main advantages that I can see are improved PPI and the obvious advantage when playing 720p videos. But a higher PPI means more processing power, which in turn means lower battery life. Also from an admittedly purely lazy point of view it means having to zoom in further to be able to read text.
A 720p display will now mean that 480p videos on youtube and the like will be upscaled and won’t look as good. ‘Just choose the 720p option’ you say. Fine, so long as you’re on wifi. Until 4G hits and is widespread (which in the UK is going to take a while) it will mean longer waits and buffer issues.
Yes I’m nit picking but I’d genuinely like to hear your thoughts on the pros and cons of a 720p display. I know there will be many more I’ve missed.
i see it from 2 sides....
720p = really nice picture quality
720p bad for some apps/games, which might no longer run properly, unless fixed, or some how the hardware can auto adjust the resolution to stretch it to fit.
720p can be a bit of a pain, if some Apps/Games developer decide to use too small of a touch area, due the larger dot-pix available in the 720p area
that also means DVD quality or lower quality videos played on the 720p will look like blurry or smeared, that can be fixed with software/hardware correction, like games.
^^ All that.
Plus, I don't really see the need for a 720 screen that's around the 4" size. Do you really need pixels that small? They'll be smaller than photons if we carry on like this and then it'll be reality that'll have to catch up with our tech
Personally, I wouldn't hold back for purely that one feature, but who knows what else is round the corner. Get a phone and let it be the best for a few months and then slowly drop down the list. As everyone always says, there's always something better coming, and if you waited then you'd never get anything.
Incidentally, I do have the SGS2, and it is REALLY nice
well definitely 1080p will be around the corner as we already stepped into the 720p kingdom
so 1080p on a 4" display would not be a long wait, but it will really make you think, what's the point of cramming so much in such a little screen
i can see 1080p to be a normal thin on a 10" tablet, but on a phone... that's a bit much
i do hope they don't go beyond 720p on any screen smaller than 5"
imagine running Windows Vista/7 on 15" wide LCD at 1080 (there are many laptops that are actually like that) it's soooooo eye strain-ful, it literally kills the eyes
i always down set the resolution back to something more readable to not strain my eyes

Do you need your reading glasses as well, so you can find your pipe and slippers?
i don't wear glasses, and i intent to keep it that way, reason why i prefer an easy reading, on 480 vs 720
on 720 i'll have to probably the the font size twice as big, to make it easily legible when you are in the car, bus/subway, or walking
no i don't get dizzy reading while doing any of the above
many people can't read if they are in a moving vehicle
probably due the same relevant issue about having to scan the text in a small device and straining your vision, while trying to keep an eye on the road and not crashing

I agree with you, therebisbreally no reason to go above 720p resolution on small smartphone devices. I myself notice my eyes begin to hurt after more than thirty minutes or so of heavy reading on my Sensation. Now I know my Sensation does not have 720p but I am just saying the size of the screen and the text on that screen is no doubt a strain on the human eye after extended reading done on the device. 1080p is definitely so,ethimg that should just make it to the larger tablets and not smartphones.
Oh and yes actually paying attention to the road while you are driving is a highly recommended activity lol.

This is just plain wrong, low resolution video will look just as good on 720p displays.

Maybe i miss-understood your question, but i am using the Galaxy SII
I never had any screen / resolution issues
Well,first off,let's not forget that Android supports changing the DPI in build.prop(I think-haven't bothered in a while).I don't think manufacturers will leave 220-240 dpi of the current devices on 720p devices,but they would rather pump it up,so that everything stays the same size,but is just crisper.That's just my thought though.
On another note,lower resolution videos won't look worse at all.Resolution in that aspect is irrelevant.The same way that you can play a 720p video on a 480p screen without problems,you can do the opposite just as well.Unless some manufacturer decides to f*ck it up with upscaling tricks and stuff that will defo make the image blurry and ugly.
The only really valid argument on the topic,in my opinion,is the possible lack of processing power,especially when it comes to GPUs.We even saw the Mali MP-400,the most powerful GPU on a PHONE (DON'T SAY ABOUT THE A5 IN THE iPAD!!!!) to date,struggle to keep up in the case of the Galaxy Note's resolution.If the next gen of SoCs doesn't improve quite a lot in that aspect,we'll see some performance drops for sure.Not to mention the worst thing,the losses of battery life in case that extra power is met.Not that I mind about battery life as long as it makes it through the day,but many many people do.
Do any of you guys know the p in 720p stands for?
It has nothing to do with resolution, which is what you are all trying to talk about.

progressive, opposed to the i of interlaced.
Technically 720i use half the vertical pixels for each frame.

They compare the LCD technology and the AMOLED technology from the HTC One and the Samsung Galaxy S4 respectively. They determined that color accuracy, image detail, contrast and blacks to be superior in the Galaxy flagship, while giving brightness and outdoor legibility in direct light to its competitor. The iPhone 5 is considered best in class for handheld mobile LCD technology when it comes to color reproduction, due to better screen calibration on a smaller panel.
This comparison finding is further supported by the reputable business "DisplayMate" conducting comparison tests on the iPhone 5 and Galaxy S4 only to determine that they're on par.

"When you deselect the Adapt Display check box you can select from Dynamic, Standard, Professional Photo, or Movie. We measured them all, and Movie delivered the most accurate color. Its saturation error in particular is much lower than that of the other modes. Movie mode's advantage over the others isn't as strong as it was on the Note 2, however."
Movie is the best mode? Movie mode looks washed out, poor and boring close to Dynamic or Adapt Display.
I don't give a damn about synthetic color accuracy. That only makes sense if you are a professional that works with imaging and you NEED color accuracy. I don't care about that, since I don't work with that. I'm just a regular user that wants to enjoy my cell phone and I want rich, vivid images with images exploding with exaggerated color, because that's what makes me feel like having a great screen, and that´s what people tell me when they see my screen and say "wow, look at those colors".
I always thought that Galaxy S screens look much better then iPhone screens, and one of the reasons for that is the natural color boosting AMOLED screens do. Sure, they are not "accurate", but they look great. Accurate = boring. Vivid colors = awesome.
Yea. I switched to Movie Mode on my N2 and it looked horrible and faded.

I much prefer saturated/richer colors, but I did wonder about color accuracy since reading other blogs/reviews/posts people have said the S4 is much less accurate than the HTC One/iPhone with regards to accuracy. I guess this sort of counterpoints those claims.
I am glad that we can chose what we want so... that's really good.
There is mode for everyone and it's great to be able to chose and have more options.
The point is. We all know OLED is not as color accurate as LCD. OLED boosts rich vivid colors that, although unaccurate, look awesome. Not to mention the perfect dark pitch and virtually infinite contrast ratio (unlike color accuracy, elevated contrast ratio is equally impressive both in theory and in practice).
Buying a OLED phone and trying to make it look like an LCD phone makes no sense to me. If I want a LCD-looking screen with LCD color accuracy, I´ll just buy an LCD phone.
^ Are you buying a phone based on the screen?
Point is that Amoled can be great on it's own but also can be good where LCDs are better and improve from generation to generation.

Blogs, pundits of tech sites and such aren't usually knowledgeable when it comes to all factors of determining a good display. I find that they more often than not base their knowledge off of general propaganda. Or they don't have the right type of technology to conduct an invasive and accurate test for gauging the quality of a display in comparison to another.
All the information supplemented in the OP comes from sources that work in the business as screen calibrate technicians; DisplayMate (http://displaymate.com/Galaxy_S4_ShootOut_1.htm) is among the most reputable you'll ever find when it comes to screen assessment, as they do calibration for a living and have the technology to properly asses. I'd rather take their word than some editorial pundit from PocketNow or Gizmodo.
I think they all have their pro's and con's, I suggest you choose what looks good with your eye's and not base on test results or peoples opinions.

OLEDs are perfectly capable to display absolute accurate colours and go beyond any other display technology in terms of output.
The problem is Samsung's presets accuracy and lack of education.
Sadly because the US variant of the S2 and S3 lacked the hardware for the display modes, that AMOLED got this asinine reputation.
http://www.phonearena.com/news/UL-certifies-the-4.99-FHD-display-on-the-Samsung-Galaxy-S4_id43874
According to UL, the screen on the Samsung Galaxy S4 offers one of the best color reproductions in the mobile industry with the broadest color gamut of up to 97% for the Adobe RGB color space. The screen is said to have one of the best contrast ratios and can be better seen under bright sunlight than the display on many of the phone's rivals.

I was thinking about linking that, too. AMOLED truly does seem like it's going to be the future for top-end displays. They really just have to improve energy efficiency with the panel, so it can push higher degrees of brightness, that should dethrone any practical advantageous aspect to an LCD. The panel from S III to S4 was a major leap forward in enhancement. Makes me eagerly curious to see what the Note III and moreover, the S5 will shape this technology into next.
I use Movie mode and find it the best for me beacause im not a big fan of saturated colors.
They just need to sort motion blur and burn in before they can get back to the top.
That article is all well and good, but doesn't take into account that side by side with a HTC One, the S4 screen is underwhelming in real world.
I have gone with Samsung since S2 as I loved that device to bits, but the screen on the S4 blew me away for all the wrong reasons, hence why I bought the HTC One.
Had to chime in as I love samsung phones, but feel they dropped the ball with this one. The S4 screen for me is not even as nice as the S3. I don't know why, maybe by trying to mimic LCD, they lost what was good about AMOLED in the first place. The "pop".
Hey, we do not have option to set always on display on Poco X3 Pro,but is there any way to do that? Or any aplication? I try some from Googleplay, but they are for amoled screens. Thanks for any answers .
An always on display makes no sense with an IPS panel.

Cut&Paste from Quora (I'm lazy!):
Here’s the main difference between OLED screens and LCD screens: when an OLED screen displays black, the pixels are powered off, so the battery is not being drained by the screen but when an LCD screen displays black, it does so by tinting the backlight dark, which means the screen is still generating light and is hence draining the battery.
An always on display requires the screen to show the time (and some extra details) constantly. In an OLED screen, this means only the pixels that are displaying the time are turned on, which results in less battery drain. But when it comes to LCD displays, there’s no difference in battery drain during always on display versus normal usage (taking into consideration only battery drain due to display).

There are no apps for always on display on LCD screen's , only if you move to an custom AOSP rom, you will find that feature (but you will experience battery draining!!!).
Also the led of your ips-panel will degrade super damn fast

Better read my post again, preferably two or three times, and then you may understand why an AoD on an LCD / IPS panel makes relatively little sense. Does it basically work? Yes it does and I have never said anything to the contrary.

yea i know, but i talk about more user's choice, not company or MIUI choice. i hope AoD still work in IPS panel.
in ur post u explain how AoD and screen work and hardware work, but here i more talk about choice AoD software. There is ton explanation about different LCD and AMOLED in youtube and i already watched it, so i no need explanation about panel.
Thankyou

yea i know, but give user's choice without rooting or change OS. that what i want or people want (maybe). there is phone out there, has option to turn on AoD. user's already (or must ) know what effect if turn on AoD. if user use IPS panel, maybe u cant longer turn on AoD than AMOLED panel. just need complex setting, simple as that
