What model tablet do you have that supports 16-bit color depth? –  Lèse majesté Jan 30 '12 at 6:44
    
Samsung tablet MZ604 –  Bushi Jan 30 '12 at 11:00

The MZ604, like 99.99% of all devices with LCD displays, is 32-bit Truecolor. That's 8-bits per channel. –  Lèse majesté Jan 30 '12 at 14:56

I suspect you're confusing bits per channel per pixel and bits per pixel.

So your "16 bit depth" tablet uses 16 bits per pixel, not 16 bits per each of the RGB channels, which would be 48 bits per pixel.

But 16 bits can't be split equally between three channels. I'd guess that two channels get 5 bits and one gets 6 bits. Think you need to confirm this.
