  • Publication number: 20210366368
    Abstract: A novel display device where a light-emitting element is turned on by a triangle wave is provided. One embodiment of the present invention is a method for driving a display device including a first pixel, a second pixel, a first wiring, a second wiring, and a third wiring. The first wiring is electrically connected to the first pixel and the second pixel. The second wiring and the third wiring are electrically connected to the first pixel and the second pixel, respectively. At a first time, the first pixel reaches the maximum luminance corresponding to first display data and the second pixel reaches the maximum luminance corresponding to second display data. The first pixel and the second pixel are initialized at a second time different from the first time by input of a reset signal to the first wiring to stop light emission.

  • Patent number: 11132969
    Abstract: A display device which achieves both a high-accuracy sensing operation and smooth input in a touch sensor unit is provided. The display device includes a display unit and the touch sensor unit. The touch sensor unit performs a touch sensing operation when the display unit does not perform a display image rewriting operation; thus, a highly accurate sensing operation is possible. A gate driver of the display unit includes a first circuit and a second circuit. The second circuit includes a plurality of shift registers. Only a display image of a region that needs to be rewritten can be rewritten. The first circuit is a shift register and designates a shift register from the plurality of shift registers included in the second circuit to operate. In the case where an image in the entire display region does not need to be rewritten, the time assigned for the sensing operation of the touch sensor unit increases, leading to the smooth input.
