with super amoled, if you use a black bg those pixels are just shut off and can save you some battery life. But the SLCD isn't as easy to see in the sunlight and i was curious if there is a difference in battery juice consumption with a white bg. Even black has to be luminated by the screen, not shut off pixels like S-AMOLED. Is there a difference between black n white on SLCD's battery drain?
I'm looking for a more technical answer with reasoning rather than "just try em both and find out".
White would be easier to see in sunlight without having to turn up the brightness past 25%.
Please don't quote me on this but I believe the difference in battery usage would be very negligible. It does take less power to display a black LCD screen than a white one but not enough to provide any noticeable difference in battery life like it does on AMOLED devices.

Thanks. I did just remember about a cyanogenmod setting to filter the color of the screen and it quote "potential battery saver". Im not sayin battery life is an issue, just curious on knowing the differences in power consumption by color. But like u said, its probably very minimal tho. My 2 past devices were S-AMOLED and I didn't bother with predominantly white backgrounds because it actually made a difference. Time to be able to enjoy the entire spectrum on SLCD without worry! Haha one of the few benefits of LCD

I think it might use more power on LCD screens. Or, at least, I remember reading that. However, back on my Hero, I tried the effect and it seemed to use the CPU more to render the effect. The phone got slower while in red, blue, etc. I think it is really only for AMOLED screens. Phones using that type of screen benefit a lot more. But I am most likely wrong. It has been a long time since I read up on this tweak.

that sucks that the phone becomes sluggish, but then again it was the hero which is 1/4 the phone the 3D is...
also, i'm trying to make sense of it being for AMOLED screens, cuz the pixels are individual LEDs (or so i think) which are on/off individually. but LCD is Liquid.Crystal.Display, which to me makes more sense to render the entire display a certain color... i dunno, probably talking outta my a$$ but hopefully someone with a definite answer can chime in..
thanks for all the info & opinions from you guys, i feel we're getting closer
When (if) we finally get this baby S-Off and devs start cooking kernels, will they be able to tweak how bright the capacitive lights are? On my device, at least, the lights are so bright they look a little pink. Is that something controlled by the kernel? If the brightness on them was dialed down, I feel like it might help.
Rabble rabble rabble.
I believe that's something that will be able to be fixed via software.
Absolutely. That's can absolutely be incorporated into the kernel. If a dev makes a configurator for the terminal emulator th u can adjust it by a percentage. We had a few configurators for the EVO and the settings were for both OCing and the capacitive button. Very useful

Devs can tweak the Capacitive brightness through kernel, Evo 3D & Sensation both can change their brightness. But there's a script that lets you change the lights from bright to dim and then off. Although Faux has managed to make the Leds dynamic based on the screen brightness, which is quite useful.
Having a dynamic ability would be great! However, 9/10 you can see the buttons without them being lit at all.
I couldn't care less about the brightness, I more hate they're so inconsistent. At home with my incadescent lights, they never come on. At work with all of the flourescent lighting where it's much brighter, they do turn on. Makes no sense man!
Could just be the lighting the sensor is more sensitive to.

Sounds pretty consistent to me. Sorry, couldn't help myself.
Yeah, I had the EVO 3D for a few weeks, and when we only had temp root I did a lot of playing around with terminal scripts, for OC and whatnot. But this is good news! Like somebody said, you rarely actually need them. But when you do, they don't even need to be very bright at all to be seen. I feel like at stock levels, it is a little overboard.
I think even having it at 50% would be more than enough. Anyway, thanks for the responses. Looking forward to such development.
Rabble rabble rabble.
i usually want my led lights as bright as possible, but i know from taking it apart and lighting it up, its pretty much as bright as the led will go, its just the tint of red on the digitizer is thick enough so the light doesnt shine through pink like you said, however maybe on yours the tint is thinner who knows. I usually change phone everytime a new one comes out, or else i would (which i still might) solder on RED leds so i can push them out even brighter red.
Led Notification ?
Speaking of lights, does this phone have an led notification light for missed calls, voicemail, texts, etc?

I agree, the capacitive keys are too bright and look pink-ish. If we can adjust them to make them dimmer, make them more of a true red, that would be awesome.
My lights are on whenever the screen is on. Is there a way to change it. I have seen post talkin about them never turning on but I rather they never turn on not always be on.

Download an app called Screen Filter. Set it to 100% to keep the normal brightness, then uncheck Enable soft key lighting option. Screen on even in dark with no capacitive lights.
I've read of several owners complaining about how bright the lowest brightness is, and others (including myself) on the dark 'splotches' on the screen in very dark settings, only recently have I pieced the two together: Motorola purposely made the minimum brightness still very illuminated in order to try and hide these marks on the AMOLED screen. It's very annoying when these are visible, and it's even more annoying trying to read or accomplish any task in a very dark setting; the screen is still so bright that it hurts my eyes.
I hope Motorola fixes this hindrance in future iterations of the Razr/Droid series.

That makes sense
This makes sense. I too have noticed the dark splotches and I thought I was the only one who received a somewhat defective one. But for me, as long as I'm not looking at a super dark image in a super dark room I cannot notice them.
But thanks for the reassurance that I'm not the only one!
Does not make sense at all - how low would the brightness have to be to see those spots if they are only visible on black background in COMPLETE DARKNESS?
Yeah, you have just discovered America.
I have the same. I only see them when the phone is docked and in night clock mode, or when I'm running screen filter to cut the light when playing something in bed.
Never seen them. Not that big an issue if they're there.

If my brightness is set to minimum and it's nighttime, when watching movies, looking at pictures, or even just navigating around the OS, I can see them, they look like water-marks on the screen.
"you have just discovered America." Is that suppose to be an insult?
My prime has always had this issue since I got it and has seemed to stick thru resets and new firmware. It looks to be a gamma issue washing out light colors. Any idea what I could do or need replacing?
AOKP has some gamma options, don't know if work though.

up your device to performance mode, and max brightness. see if it looks better. ive noticed the auto settings from asus dont just change brightness and processor voltage. it seems to change the OLED power. on power saver its obvious on mine.
all icons looks muted, hard to read. turn to performance and its sharp.
dunno
You know what? Changing to performance actually changed the gamma a bit and its much better looking now. That's crazy, I had it on balanced. I'll test it out some more and see if its good to go and see if I can get some shots of the difference.

Glad that helped. Wasn't quite sure myself if it was just my eyes or a real change on screen. But it seems to work
Do you have such stains? I hear this is normal among AMOLEDs.
welcome to mass produced (aka economically viable) OLEDs...
Some patterning or colour patching is inevitable even from new. Blue or Grey backgrounds tend to show patches up more. Very low brightness shows a greenish cast on the left of the screen too.
It took more than a decade before LCDs could be produced in volume with a very low dead pixel yield.
We have a dozen GS2s at work and they all have minor screen issues. From new. They do get worse or even change position over time (many months) as the pixel level elements shift in luminosity.
Also note that if the phone is warm, the effect lessens.

Thank God I don't have dead pixels. At least this patch I got is visible only on dark-gray / medium-light (so-to-say, idk) brown. I'd rather have that than dead pixels .
Actually, if I start Screen Test, the patch is visible on ALL colors. On blue/red/green, it is less visible. On white, it is most visible. Also, when displaying full whites, the color is not homogeneous. Vertical and horizontal lines seem to be present ALL ACROSS the screen. These lines are visible on white, yellow and such colors.
At least I don't have ghosting effect and the whites are actually white, not yellow - as it was on Gingerbread (yeah, software problem, eh?).
So... the patch appeared to have vanished after running the fix (which rapidly ****s four colors) for half an hour, because the screen was a bit warmer... and as it cooled down, the patch has shown its face again. Oh well...
the galaxy note and s2 super amoled screens are prone to burn ins, very common, you need to eliminate risks involved.
Turn off auto brightness, lower the brightness level, shorten the time youre screen stays awake for, and if youre using themes, avid the blue themed ics ones, although they look nice, the blue themes are one of the biggest culprits of the burn in issue and before ya know it youve got a battery image burnt in.
i notice it looks like you have a blue theme or something, my mate had same issue, what can ya do, its a pain and well probably all suffer it, whereas htcs dont have the issue, they just suffer dead pixels a lot, but hey, id soone have slight burn in than dead pixels i guess

F*** !
MIUI uses white & orange. Are those colors dangerous, too?
I mean... what colors should I avoid the most? Besides blue - I get it, it's bad (again, F***).
Anything that turns the RGB elements hard on (!). So high brightness only and white is worst as this is RGB full on, then pure red, pure blue, pure green. Cyan, yellow and magenta are less risky. In theory.
In practice and the real world, just keep the brightness down a little and you'll get years out of it. And save battery - the screen is THE major power consumer...

+1 absolutely right, follow these simple rules and all should be good.
White requires all three elements (RGB), right? Blue = B. Which one should I stick to...? My logics tell me blue, but I hear AMOLED's blue color is so pure because of a compound from algae (rofl) and it wears off more quickly (if any of that makes sense).
Cyan, magenta, yellow... Yeah, I don't have that on AOKP, lol. And neither would I want a yellow theme. Magenta would be nice, though.
RGB... hell, those are the primary colors. How about we use black, with polarised glasses? That'd be a good deal, since I wear glasses, lol.
Seriously, guys, what do YOU do to make sure the screen doesn't get damaged over time? Don't tell me you're using a yellow-black theme. And setting the screen brightness to 50% or more is required outdoors, so...

I just went to a showroom today. Seen the Galaxy Nexus there. It's on, with the brightness set to maximum, 12 hours a day, and it's been like that ever since they put it there - more than 3 months. Seeing anything strange here?
well, as a rule i dont have wallpapers that have bright vibrant colours, i find it annoying and painful on the eyes, and if you have shortcuts on the homescreen it gets to looking messy, so i stick with dark colours, to be honest most of my wallpapers are black or almost black and my brightness is set at around 20%, and i dont struggle to see it outside in sunlight or anything, but this is just my prefernce, im sure everyone has different tastes, i think you should just enjoy your phone and use it how you wish, but try to avoid having it too bright, it should be ok.

I'll stick to the stock AOKP theme (blue, that is); but I will be careful not to raise the brightness above the point of 50%. And even if I do, I guess setting it to the maximum point for a few minutes (when the sunlight is very strong) wouldn't hurt...
Oh and mind archiving your black and dark wallpapers and sending them over to me? Please (I'm always happy to pile up such wallpapers)
