Patent number: 5691739Abstract: A driving device, which drives a display section that consists of a plurality of liquid crystal display elements that are connected to signal lines and scanning lines and that are disposed in the form of matrix, includes a scanning-line driver, a signal-line driver, and a compensating device. The scanning-line driver is for releasing to the scanning lines a scanning signal for selecting the scanning lines successively. The signal-line drive is for releasing to the signal lines a display signal for displaying images in synchronism with the scanning signal. Finally, the compensating device which, during a compensating period that follows a display period during which display signals corresponding to one picture are transmitted to the signal lines, applies to each liquid crystal display element a compensating voltage or compensating pulses that is capable of cancelling a lowering in an effective value of a driving voltage for the liquid crystal display elements during the display period.Type: GrantFiled: December 23, 1994Date of Patent: November 25, 1997Assignee: Sharp Kabushiki KaishaInventors: Hidetsugu Kawamori, Nobuaki Takahashi

Patent number: 5598178Abstract: A liquid crystal display is provided with a dummy-capacity driver for applying dummy capacities to scanning lines, in accordance with the number of on-state display elements and the number of off-state display elements in each scanning line. This arrangement makes it possible to suppress distortions that tend to appear in a waveform of the driving voltage upon inversion of the polarity. Thus, it becomes possible to obtain liquid crystal images of high picture quality with virtually no crosstalk when displaying any pattern.Type: GrantFiled: December 22, 1994Date of Patent: January 28, 1997Assignee: Sharp Kabushiki KaishaInventor: Hidetsugu Kawamori
