I know that the samoled screens conserve power when displaying blacks, as the light under each pixel is actually off. Does the same hold true for the pentile screen on our photons?

Just a quick question...
Will using an alarm clock/nightstand app where the screen stays on all night damage an AmOLED screen?
Thanks in advance

Most "good" alarm clock apps have night mode that dims your screen to almost no brightness, and that constantly moves the digits on the screen to avoid burn in. The dimmer you set the screen, the longer it will serve you. Remember, OLED pixels, just like Plasma pixels, just like LCD backlight, lose brightness with time.
If I meet you 6 months from now, with my SGS2, and you buy me a brand new SGS2, and we compare all 3 screens on full brightness, we will see that the present I am getting is the brightest, my old SGS2 is the second-brightest, and your alarm-abused SGS2 is the least bright.
Thank you for your advice. Ive used the apps before with iPhones and the Xperia Arc but wasnt too sure on it effects on AmOLED.

Yes you can burn in an amoled screen. So make sure your app moves the image and doesn't keep a constant static image in any one location.
Coming from the gnex with an amoled screen, blues and black colors saved more battery. What colors, if any, make the LCD3 work less thus saving battery?

On an LCD screen, all the light is supplied by the backlight, and the color is affected by what the actual LCD panel allows to pass through it. This means that the backlight (which by far consumes the most energy of the screen) will use the same amount of power regardless of what is displayed on the screen. The color may slightly affect the amount of energy used, but not significantly like with an AMOLED screen.
This will give you an idea of the amount of how much the power consumption varies based on color.

I was thinking that but I wasn't for sure. Thank you for the link and the informative answer. Over 100 views and I didn't think I was going to get a reply hahah.

Anyone know if the true HD IPS+ screen is similar to the AMOLED in that black pixels dont use as much power? For example, would we have the same power saving benefits of black wallpaper and inverted apps as a phone with an AMOLED screen?
Nope because the LCD tries and replicate black's SDI the screen is still on and using power

I don't know, are you sure? I would be willing to bet that even though power is used to emit something, it's only a fraction of the power used for bright colors.

As far as I'm aware, LCD is still continually and constantly backlit, unless you have one of those dynamic backlighting schemes like on some TVs where there are zones that dime to provide blacker blacks. The backlight is a separate source as LCD cannot emit its own light.
OLED provide the source of the light as well as colour, so when the pixel is black, it is actually off.
So, REDFOCZ's response is correct.
AMOLED screens don’t require a backlight. The benefit of losing a backlight is apparent: these screens are able to produce blacks so deep that the screen pixels can shut right off. This can save battery life if you use a background that is dark in color or black. LCD screens still require the back light on those using power.

Either way I have to say I get awesome battery life on this phone

Thanks for all of the thoughtful responses everyone! I don't even know why i'm trying to milk more battery life out of this phone (old habits from the captivate days i guess)! My experience with the battery life is great!
Can't find the article I thought I bookmarked because the question came up on the Infuse forums months ago but-- REDFOCZ- +1

Will using inverted apps save battery on the nexus 10? Or does it only work for amoled screens?
That trick only works on AMOLED devices. Sorry.
Yeah that would be nice

The LCD back light is always on using battery, no matter what color your displaying. With AMOLED, only the sections of the screen displaying color are on, and the black sections are portions of the screen that you could say are "turned off". AMOLED works by exciting a membrane with electrons, without using a back light.
To quote myself from the Nexus 4 forum:
"Simple answer: There is no affect on battery life. It will drain just as fast on white as it will on black.
Basic screen technology lesson incoming...
The image displayed on a regular LCD screen (aka most phones) will not affect your battery life. Only AMOLED screens (aka most Samsung phones) are affected by this phenomenon because the image is also the lightsource.
Battery life with LCD screens is affected by the backlight brightness. The backlight covers the whole back, is always white, and only shines through the LCD to allow you to see the image. Turn up the brightness, consume more power. Turn down the brightness, consume less power. Has nothing to do with the image on the screen.
Amoled screens do not shine through anything, the image they produce is also producing the light. That's why blacks use no power (off), and whites use max power (all on).
The end."

Anyone notice that when the screen is at its brightest in the sun and you are on a light or white screen there is a vertical bar running down the left side of the screen? The screen will also exhibit blotchy spots throughout the screen. Is this a characteristic of AMOLED screens in general?
