Matrix type liquid crystal display device |
摘要 |
Burning and flickering effects of a display screen in a matrix-type liquid crystal display device using an anti-ferroelectric liquid crystal medium are avoided by controlling the duration of the holding period to a certain length. A control circuit measures the cycle of the input of the picture signals to one picture frame, and the duration of the blanking period is controlled according to the result of the measurement in order to keep the duration of the holding period constant.
