DISPLAY APPARATUS AND DISPLAY APPARATUS DRIVE METHOD

摘要

An EPG extraction unit extracts EPG information. A program type identification unit identifies the type of the broadcast program from the extracted EPG information and outputs a ratio change signal for changing the ratio of the image display period and the black display period according to the type identified. A drive pulse generation unit generates a gate driver control signal for changing the write in timing of the twice-speed image signal and the twice-speed black display signal in one field period according to the ratio change signal. A gate driver changes the write in timing of the twice-speed image signal and the twice-speed black display signal according to the gate driver control signal so as to change the ratio of the image display period and the black display period.
