Patent number: 7595780Abstract: The liquid crystal display device has a liquid crystal panel in which liquid crystal cells are disposed in intersection areas of scanning lines and data lines, respectively. A picture signal and a synchronous signal are supplied via external terminals, respectively. A timing controller generates a driving timing of the scanning lines and a driving timing of the data lines in response to the synchronous signal. Further, the timing controller varies at least one of the driving timing of the scanning lines and the driving timing of the data lines according to a cycle of the synchronous signal in order to keep a writing time of the picture signal supplied to the liquid crystal cells constant. Therefore, it is possible to keep the writing time constant even when the cycle of the synchronous signal varies, which can prevent the deterioration in display quality.Type: GrantFiled: July 28, 2004Date of Patent: September 29, 2009Assignees: Fujitsu Limited, Au Optronics CorporationInventors: Koichi Katagawa, Yasutake Furukoshi, Katsuyoshi Hiraki
