Hi,
I am currently looking at the AUO M190EG01V0. Would this be the
luminance uniformity which is 75 to 80%? The board would also be
designed for smaller modules.
For a FPGA point of view, I guess the functional blocks are as follow;
Analog RGB-> YUV->gamma correction->Hue, saturation, contrast->Digital
RGB (8 bits per color for a 24 bit screen)->LVDS output
For the smaller module would I have to scale it down to 6 bits per
color by rounding the RGB values from 8 bits to 6 bits?? Would tha
affect the gamma correction??

Hi folks,
How do I calculate the gamma values for LCD module? I am trying to
design a LCD driver board.

What LCD module? A started point is from the LCD spec. Look for
things relate to the LCD illumination charactistic then figure out the
equation... If it's linear then you don't need the gamma correction,
unless your board is designed for optical clinic
