As far as I know:
OLED is transparent, and doesn't need a backlight (as it provides its own).
So why can't you have an eInk display behind the OLED display? Switch off the OLED when you want to use the eInk, and turn the OLED back on when eInk is done?
For touchscreen usage, instead of glossy glass for capacitive, use infrared or acoustic pulse (what the Kindle Touch uses), so it's not glossy at all (to read eInk and OLED screens better).
If OLED screen requires a dark back panel to show the colors effectively, use the eInk display to show all black >.>.
That actually sounds like a really good idea, I would buy a phone like that.

Yes, really good idea - if black BG is needed for OLED, keeping eInk black doesn't consume any power at all.
Well, you can contact some manufacturer and tell them your idea
If I was you I would really edit your post to say that this is your idea and no one else can propose this, because I really think if you were to propose this it would go through.

Its strange but noticed that my phones whit coloring looks a little more greenish than my.friends vibrant. And then i compared my captivate to my gfs and here whites r more white colored like my friend.
I don't get it, did a lot if the models come with different screens that display differently?

seems like someone needs a little more research
wait what no the whole entire galaxy s line has super amoled hmm its maybe the tint thats changed a little
A Super ALOMED screen is still AMOLED.
Anyway, just because it is the same model screen doesn't mean there are not variations in the mfg process that could cause slight differences. With the amount of screens that they are pushing out I am sure they are using equivelent components that may not be exactly the same.
Also depending on the allowed tollerances, 2 screen with slighly different temperature ratings could both still pass QA.
Personally my screen is very cold, whites tend to have a slight tint of blue to them. I prefer warmer displays but the SAMOLED is too nice to ignore even if the picture is cold.
It's possible that the screens are going through a rapid break-in process and the screens look different because they have been used different amounts.
Or it could just be differences within manufacturing tolerances.
Well this all makes sense. Mine has a greenish tiny, my gf and frie.d have a warmer orange redish tint and i have a lil blue green tint.
This follows the rgb thing in a way. I think different screen manufacturers favor one of the latter.

They may make the screen, but that doesn't mean they make all the materials used to manufacture the screen.
Different materials cause wider manufacturing tolerances. It's not different manufacturers favoring one color over another in this situation.
I really wish there could be a straight answer instead of speculating why our phones are cooler and warmer in color. I mean the screen still looks freakin great, but i wonder if there is a way to manipulate it through software.
Sent from my SAMSUNG-SGH-I897 using XDA App
I agree. I would love it if phones finally started letting you adjust color temperature like computers.
My screen is also blue. I´m waiting it to go away in time, but I´m really sceptic about it...
It´s easy to test after you download somekind of a flashlight app and use it in the dark, mine gives the same blueish light like those cheap led-flashlights, so definytely not real whites in my unit...

There is no such thing as real white when it comes to light (what your screen is putting out). I would prefer the screen to be warmer, but it is still white.
For more information look up color temperature.
The HTC Desire and Nexus one on Cyanogen Mod both allow you to adjust gamma settings via software. So this can definitely be corrected. All it requires is additional dev magic and a dab of patience.

That's interesting,i hope someone is working on color temperature too.
Somebody else mentioned it but "manufacturer tolerance" is what causes this. It would be possible to make them all exactly the same, but the costs of the device would go up significantly. Usually the difference is so minute that most people never notice.
You see the same thing with mass produced digital projectors and tvs. If you were to take 10 new projectors of the same model and line them up side by side you would find not all the pictures were exactly the same. Due to manufacturer tolerance some may be slightly brighter or dimmer and colors may be a little more vibrant on another.
Blue Tint
Yes, Super Amoleds are coming in all forms of Tint. Some are lucky to get nice warm whites. Other people get green, blue, greenish blue, or even yellow tints.
maybe even pink tint like the amoled on zune hd

Does this app really work to lower battery useage? Or is it just a placebo effect? Can I set my screen to 100% and use the filter to save batt?
Genuinely curious.
Sent from my Desire HD using XDA Premium App
depends on the screen. pretty sure the DHD has an LCD, though that is from memory as I have never used one. If so, then no you wont see any battery life changes because the type of screen will turn on all pixels at all times no matter what color. That is the nature of the screen.
On the other hand if you have an AMOLED screen (as I do) the screen can turn pixels completely off if they are black and use less power if they are darker. These screens are most commonly used in Samsung phones, I'm not sure about any other manufacturers.
You can still benefit from Screen Filter because it will make your screen not as bright to your eyes, which is good if you need to use it at night and don't want to be blinded/wake up your spouse/whatever.

Thank you. Will have to check the box when I get home for LCD or smiled.

OLED screens blow away LCDs in almost every way, except for one, longevity. The blue emmiter subpixels wear faster then the others. Static images especially ones using blue subpixels can damage your screen.
I notice that most themes use loads of blue everywhere. That is also the color which burns in the quickest on OLED screens. Also static images like the battery, wifi etc at the top are always there. This also can result in screen burn. Unless you want your screen to start to look like an old Pac-Man arcade screen care should be taken.
Since this is the Infuse section and everyone has an OLED screen has anyone made a theme using colors with as little blue as possible (white uses blue sub pixels so that don't count). Colors with mostly red green mixtures are the most OLED safe. I wouldn't mind if those static indicators on the top at least were all in yellow, red etc and at a lower brightness than the rest of the screen.

OLED, Super AMOLED, AMOLED plus, super duper AMOLED 12,000 +, all the same tech.
The characteristics of the emmiters in Organic Light Emmiting Diodes are exactly the same, blue wears faster. The only differences are how it is driven (AM= Active Matrix) and the plus is just the pattern of the subpixels (RGB or pentile). If it has OLED anywhere in it, your screen WILL get images burned in if you have static images on the screen for too long and blue will wear sooner, much sooner, than the rest of the colors.
So BE CAREFULL! if you have your brightness cranked avoid static images, unless you like them so much that you want them permanently part of the screen!
Is there a way I can hack a ROM to just change the graphics? I am no coder but I can tweak the art.

Sent from my SAMSUNG-SGH-I997 using xda premium
actually i do have a solution if you dont mind things looking funny. other than looking for themes that have less blue and white and purple you could download chainfire 3d and use one of the night mode settings. the red or amber or green settings should help. chainfire 3d is some kind of intermediary driver that can allowq the gpu to process apis for other gpu's (assuming you have the appropriate files that are surprisingly hard to find but i have copies if anyone needs them for a specific game or anything) but one of the features is for either night viewing or for power saving and (assuming you have oled of some kind) and it will selectively remove or reduce the levels of the different colors. this could also be good for using your phone as a hud (heads up display) or just making navigation a little less distracting at night.
edit; now ther eis a plugin for the pay version that will automagically change color settigns based on light conditions and time of day so you can have full color when it's important and reduce blue in the evening so it's not so blinding and to save your screen from excessive blue burn in. it can also set the colors according to color temperature or custom rgb mixing.

As often as new phones come out on the market, I'll probably upgrade my phone before it has a chance to overdose on blue.
Besides, isn't that what your auto screen shutoff feature is for?
When you are actively using you're phone which means the screen is constantly changing, I don't see much chance of images getting burned onto the screen. If you like to leave your screen on and look at the pretty pictures, that might be different, ie. you will risk burning images onto your screen!

Except that some things don't really change much while using like the battery, clock, wifi etc at the top of the screen. Mine came flashed with a custom ROM (bought used) and with the theme that is on there the guy who made it went mental with blue. Everything is blue, even the wifi and battery charge indicator.
Hey everyone, I bought my HTC One S used, and at a discounted price because of screen burn-in. The burn-in isn't noticeable at higher brightness settings, but when there is a dark background applied, or when the backlight is dim, you can clearly see burned in areas.
Has anyone had any success using any burn-in removal techniques with apps like Display Tester?

What exactly is screen burn-in? Is it the same as the screen has different color depending on what angle you are looking at it? My experience is when i look directly on my screen, it show some yellowish in white background, but when i tilt it forward or backward, the white becomes white with no yellowish color. And when i turn it sideways it become pinkish.. do you think my screen is busted? Or is it what you call the screen burn-in?

Notice the faint icons? As to fixing it, I don't believe there is a way other than replacing the screen. It happens when an image is displayed without movement. It sort of "burns" into the screen, and when viewing something else, its slightly visible, thus "ghosting"
As for the yellow tint you see in the whole screen, I believe some displays are just like that.

tbh i wonder what would happen if you attempted to burn in the color inverted (dont do it, lol)
But most likely a new screen, which isn't too expensive.
If you had a big enough discount, it'd be no problem.
Im using comfort view round the clock because the yellow stainig seems to round out the natural blue tint of the display. Not sure what is more color accurate but my eyes adjust easier to the yellow tint. Lol! Funny i didnt think the cold hue screen would bother me.
Do you like the screen? :laugh:
I use the comfort screen all day too
Me too! Its pleasing to the eyes.
Same here, switching now back to normal seems to have a blueish tint to it maybe the colours aren't calibrated right from the box...but comfort view just seems so normal now.

LOL cuz your eyes adjust!
try sitting at a color-accurate monitor for a few hours or close to your tv then switch or compare side by side to another screen! if i go v20 i see it blue and feel my eyes need to adjust to the white. if the comfort view is on i feel my eyes adjust more quickly. if i view either without comparison they look normal but switch one to the other and comfort view looks more normal to me even though i know they intentionally mess it up for yellow!! haahhaa...
srsly tho, i dont think their panels have so much variance that you got accurate one and i didnt... but maybe that would sux. once again, only visible in comparison!
glad you like it! it's nice phone. not sure i understand the fetisch with locked bootloader but hey... whatevz. i\ll be happy if we oreo in april.
100% comfort view all day! Lol! Yes, the natural color calibration on the v20 feels cooler than usual but it's quite accurate in fact. The reason we feel this way is due to the immense number of AMOLED display panels on the market these days, which by nature, are MUCH warmer than any other panels. Not to mention over-saturated in their colors.
That also begs the question, is the color-accurate monitor, or TV you're using, an AMOLED, plasma or IPS LCD panel? haha (;
Either way, I enjoy comfort view too!
