STRUCTURE OF COLOR THIN FILM TRANSISTOR LIQUID CRYSTAL SCREEN DISPLAY DEVICE ON THE GRAPHIC CONTROLLER

摘要

Conventional desktop videoconferencing system using a large CRT (Cathod Ray Tube) color screen has caused a lot of inconvenience to users of the videoconferencing system depending on the limited location and the installation space of the videoconferencing system.;Therefore, the present invention uses an additional matching circuit to the conventional CRT (Cathod Ray Tube) output type graphic controller that does not support TFT (Thin Film Transister) color liquid crystal display, TFT, Disclosed is a structure of a TFT type color liquid crystal display which can be used by attaching a type of liquid crystal display to a graphic controller of an existing CRT output type.
