iPod touch How many colors can the iPod touch display?

[cLin]

I can't seem to find that specification anywhere on apple's site. They mentioned that the 5G iPod display is "2.5-inch (diagonal) QVGA transflective, over 65,000-color liquid crystal display with white LED backlight."

I want to know how many colors it can display on the LCD screen (it's 65,000 for the 5G).

i learned about this in compter science
the number of colors it can have must be a power of 2
2^16 = 65,536

Where did the 16 come from? Just curious.

theoretically, it should be able to support all combinations of RGB @ 256 (assuming you include the 0 values) so 256^3 = 16777216. Now some of those colors are going to be the same shade, but they are all technically different.

I believe that the 16 in 2^16 comes from the fact that it uses a 16-bit graphics processor.

I heard rumors that it has 18-bit color depth, can anyone confirm that? How come Apple doesn't list this damn thing on its spec page, you'd figure some people would like to know.

Well, I'm colorblind, so significantly fewer shades for me. Particularly between red and green. I see one color for those two....I call it greed. Which is fitting since red's the color of blood and green's the color of money. Blood money greed.

No it comes from the fact that each pixel is displayed using 16 bits, with each sub-pixel (RGB) using 5.33 bits.

No it comes from the fact that each pixel is displayed using 16 bits, with each sub-pixel (RGB) using 5.33 bits.

Actually, the green (being the color the human eye is most sensitive to) usually steals the 16th bit. That makes it:

Red: 5 bits
Green: 6 bits
Blue: 5 bits

(There are other ways that devices will allocate bits between colors, but this one is by far dominant)

16-bit color is common in mobile devices, so I'd put my money on the touch having a 16-bit color depth. If it isn't 16-bit, it's definitely 18-bit (6 bits per color).

According to anythingbutipod.com it can display only 65,536 colors (16-bit).

Here's a question: has anyone ever looked at their touch and seen a color it couldn't display? Ideally it would display millions of colors, but it looks pretty spectacular to me.

Try to compare Ipod Touch screen with amoled screen (iriver clix 2) or even the same LCD screen from Samsung P2:

It's kind of hard to compare anything in those pictures.
