LCD-TV DRIVING SYSTEM AND DRIVING METHOD THEREOF

摘要

An LCD(Liquid Crystal Display) TV driving system and a driving method thereof are provided to change only a setting value of a selected display item without canceling an existing display mode. A TV system driving member(210) includes an OSD(On Screen Display) input processing member(212) for receiving and processing an OSD control signal. A micro-controller(214) performs data communication with the OSD input processing member and outputs a proper processing command related to the OSD control signal. The OSD input processing member discriminates whether the OSD control signal is a specific video display mode setting change signal or a specific display item setting change signal and outputs an inherent signal to a back light driving member(230) and an LCD driving member(220).
