Patent number: 10803825Abstract: There is provided a display device that can suppress occurrence of abnormal display caused by “differences in the settling time of data voltages” between the positions of source bus lines. An output circuit in a source driver is configured to selectively output data voltages and predetermined voltages (e.g., positive-polarity and negative-polarity gradation voltages corresponding to a gradation value at an intermediate level) other than the data voltages. A display control circuit is provided with a register that holds information identifying source bus lines whose charging rates are to be adjusted; and a charge sharing control unit that outputs charge sharing control signals based on the information held in the register. Based on the charge sharing control signals, the output circuit applies the predetermined voltages, for a certain period, to source bus lines whose charging rates are to be adjusted and then applies data voltages to the source bus lines.Type: GrantFiled: January 24, 2018Date of Patent: October 13, 2020Assignee: SHARP KABUSHIKI KAISHAInventors: Kazuo Nakamura, Masaaki Nishio
