[Samsung Galaxy Nexus] patrickl:
Indeed, this pentile display is at a much higher resolution, but also the green subpixels are split up instead of using an extra white subpixel. Resolution wise there is hardly a loss with this new screen.

The only problem that remains is that the matrix is diagonally oriented and that amoled suffers in color depth when you give it less brightness to play with. Which shows as a faint cross hatched grain if you really push it.

I took a macro picture of the screen of the Galaxy Nexus compared with that of the HTC Sensation's 960x540 screen. According to the haterz the Sensation would have a higher resolution than that of the Galaxy Nexus (since the GN would have only two thirds of the reported resolution)

The picture quite clearly shows that this is not the case. The letters "dro" (from Android) look much defined on the Galaxy Nexus screen.

I'd be surprised if a full RGB matrix would actually be able to show visibly more information (render smaller fonts). I can see fonts that are so small on this screen that I'm unable to read them because my eyes can't read text that small rather than that the screen would unable to render them.

Does this extra resolution show pixelation with poor quality bitmaps? Of course it will. That's not a fault of the screen. Will it show imperfections in poorly rendered text. Again, sure it will, but that's not a fault of the screen. That would be like blaming a microscope for showing bugs in what looks like clean water to the naked eye.

I also checked the color temperature of the screen. Mine comes out at 5500K. That's the same as you get in bright daylight.

For people unfamiliar with the principle of color temperature (or white balance), there is no such thing as "white" light. Even "white" sunlight has a different color at different times during the day. Lightbulbs and fluorescent lights have different "white" color temperatures too. Also our computer monitors have different color temperatures.

A typical computer monitor will be calibrated for around 6000K to 6500K. That's the sRGB standard for monitors. Compared to sunlight this "white" will look blue. When you only look at your screen it will look white though. Your brain compensates for color temperatures, rendering each color temperature as white (after some adjustment time).

Alternatively, when your eyes and brain are adjusted to this color temperature, the sun's white light will actually look yellow. The same thing happens with the Galaxy Nexus screen. Read something on your computer monitor and then look at the Galaxy Nexus. It will look yellow.

I have a monitor calibrated for photo editing so this is set at 5500K (a monitor for print work needs to be at the same color temperature as sunlight). The Galaxy Nexus looks perfectly white when I hold it next to that.

If you sit in a room lit with lightbulbs (around 2700K), then this light is much warmer (more "yellow") than sunlight. When you are adjusted to that and then look at the Galaxy Nexus, the screen will look blue.

So it will depend on what your eyes/brain are adjusted too which they will consider to be white. Just look at the Galaxy Nexus and it will appear white.

The color temperature of the HTC Sensation is a bit higher at 5700K, so that would look less yellow to someone coming from a computer monitor. Or put them side by side and the sensation looks blue and/or the Galaxy nexus yellow.
