Dear all,
could you please someone explain me how gamma correction in lcd TVs works? I know that there are some reference voltages and RGB signals which are going to DAC. But I do not principle how it works.
Thanks

I don't know much, And actually gamma may not be something simple to define,But It’s definitely a good thing that when you buy a new LCD TV, you are not required to calibrate the gamma. This would be quite frustrating and impossible for most. The TV manufacturer does the initial tough work by setting the transfer function of the source driver DACs such that the panel has their desired non-linear gamma response.

You can find more informations here about the Gamma correction :

And about the RGB color model :
