DISPLAY APPARATUS AND DISPLAY APPARATUS DRIVE METHOD

摘要

An EPG extraction portion extracts EPG information; a program type decision portion decides the type of broadcast program using the extracted EPG information, and outputs a ratio modification signal to change the ratio of the image display interval to the black display interval according to the program type; a driving pulse generation portion generates a gate driver control signal which changes the write timing of a frequency-doubled image signal and frequency-doubled black display signal in one field interval, according to the ratio modification signal; and, a gate driver changes the write timing of the frequency-doubled image signal and frequency-doubled black display signal according to the gate driver control signal, to change the ratio of the image display interval to the black display interval.
