Publication number: 20170061912Abstract: In one embodiment of the present invention, each pixel includes first and second subpixels. CS bus lines connected to the respective storage capacitors of the first and second subpixels are electrically independent of each other. A CS voltage has a waveform that inverts its polarity at least once a frame, which includes a first subframe for sequentially scanning a series of odd rows and a second SF for sequentially scanning even rows that have been skipped during the first SF.

Patent number: 8698724Abstract: In one embodiment, a liquid crystal display device is disclosed in which a gate driver applies a gate-on pulse so that a second period is longer than a first period. Among gate-on pulses applied before the moment of polarity inversion of a data signal, the last end of the gate-on pulse nearest to the moment of the polarity inversion is earlier than the end time of the horizontal period during which the gate-on pulse is applied. The first period starts at the last end of the gate-on pulse and ends at the end time of the horizontal period during which the gate-on pulse is applied. The second period starts at the moment of the polarity inversion and ends at the moment of the application start of the gate-on pulse nearest to the moment of the polarity inversion among the gate-on pulses applied after the polarity inversion.Type: GrantFiled: March 25, 2013Date of Patent: April 15, 2014Assignee: Sharp Kabushiki KaishaInventors: Masae Kitayama, Kentaro Irie, Fumikazu Shimoshikiryoh, Toshihide Tsubata, Naoshi Yamada

Patent number: 8471793Abstract: In a liquid crystal display device according to one embodiment of the present invention, when the polarities of the source signal voltages do not change over a plurality of horizontal scanning periods, the image write pulse of the gate signal supplied to a gate bus line that corresponds to pixels along the jth row rises before the source signal voltages change to values that correspond to pixels along the jth row. Next, the image write pulse of the gate signal supplied to a gate bus line that corresponds to pixels along the jth row falls, and then the image write pulse of the gate signal supplied to a gate bus line that corresponds to pixels along the kth row (j?k) rises. The polarities of the storage capacitor signal voltages applied to storage capacitor bus lines that correspond to sub-pixels of pixels along the jth row are inverted after the image write pulse of the gate signal supplied to a gate bus line that corresponds to pixels along the kth row rises.Type: GrantFiled: April 22, 2008Date of Patent: June 25, 2013Assignee: Sharp Kabushiki KaishaInventors: Kentaro Irie, Masae Kitayama, Fumikazu Shimoshikiryoh, Toshihide Tsubata, Naoshi Yamada
