Does anyone do time based dithering to increase color depth? If a monitor can only control color to 8-bits, but has 10 or more bits of color data coming in, it could shift the pixel rapidly between the desired colors. I'm not sure if our eyes would be able to see a rapid 1 color step change in any single pixel, and it should break up the color banding that we can see.
Is this technique used anywhere?
- brigade 13y agoYes, all non-IPS laptop displays for instance. They're actually 6 bits and use temporal dithering to display 8-bit color. And indeed, most "10-bit" panels are 8-bit with FRC.
- lstamour 13y agoAh don't get me started on how I hate being lied to by monitor manufacturers. I have to start looking for 14-bit LUTs before I begin to trust that the panel might actually be 10-bit. Then again, I've a 8-bit with FRC and can't tell the difference. They both oversaturate as much as I'd like them to. :)
