Structure of a color liquid crystal display of a TFT-type in a graphic controller

摘要

A desktop type video conference system using a color screen of a conventional large CRT (Cathode Ray Tube) method is causing a lot of inconvenience to the users of the video conference system depending on the limited space and the installation space of the video conference system.;Therefore, the present invention uses an additional matching circuit in a conventional CRT (Cathode Ray Tube) output type graphic controller which does not support a TFT (Thin Film Transistor) color liquid crystal screen display, Type liquid crystal screen display device can be attached to a conventional CRT output type graphic controller and used.
