on video VDD and AVVD voltage production mode by the TCON board

 This episode deals with the way in which the Tcon board produces the various voltages for the power supply of the screen. In this video, the mode of operation of the boost and buck converter is detailed. These 2 circuits are located in the DC-DC converter of the TCON board. The Boost Converter produces the AVDD voltage. The Buck Converter produces the VDD voltage also known as V Logic.

  presents an electronic board called T Con which is an abbreviation of timing control. This board is used in LCD TVs. Its location and its role are explained in a succinct manner without going into too much technical detail.

  The electronics constituting a Gamma chip that we find in the TCON card of a TFT LCD TV is exposed as the reference AS15 and AS19. Here is detailed the difference between a classic gamma chip and those 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.
