  • Patent number: 11256361
    Abstract: A display device that achieves both high detection sensitivity of the touch sensor unit and smooth input on the touch sensor unit is provided. A method for driving a display device includes a first period and a second period. The display device includes pixels, a gate driver, and a touch sensor unit. The touch sensor unit detects a touch in the first period and stops detecting a touch in the second period. The gate driver supplies signals to some of the pixels and does not supply signals to the other pixels in the second period.

  • Patent number: 11127357
    Abstract: Techniques for implementing and/or operating an electronic device, which includes a display pixel that emits light to facilitate displaying an image during an emission period and a data driver coupled to the display pixel via a data line. The data driver generates a data line voltage signal based on image data that indicates target luminance of the display pixel in the image and supplies the data line voltage signal to the data line during a non-emission period preceding the emission period to facilitate writing the image to the display pixel. Additionally, the data driver supplies an intermediate voltage greater than a ground voltage to the data line during the emission period in which the image is displayed to facilitate reducing luminance variation in the image resulting from a leakage current flowing between an internal node of the display pixel and the data line during the emission period.

  • Patent number: 11126349
    Abstract: Disclosed are a display device and a control method. The display device includes: a transparent substrate; a transflective film disposed on a first side of the transparent substrate; a display screen disposed on a second side of the transparent substrate, the first side being opposite to the second side; and an infrared gesture recognition circuit disposed on the second side of the transparent substrate, where an orthographic projection of the infrared gesture recognition circuit on the transparent substrate and an orthographic projection of the display screen on the transparent substrate do not overlap each other; and the infrared gesture recognition circuit is configured to recognize a gesture at a side of the transflective film and control interface display of the display screen according to the determined operation gesture.
