The Gamma chip of the TCON board and the role of the opamp configured as a voltage follower

In this video is exposed the electronics constituting a Gamma chip that we find in the TCON card of a TFT LCD TV as the reference AS15 and AS19. Here is detailed the difference between a classic gamma chip and those which are known as programmable. For the clarity of the presentation are recalled some basic principles in electronics as the voltage divider and operational amplifiers (opamp) especially in voltage follower configuration.
