  • Patent number: 11036272
    Abstract: The present disclosure relates to a method applied to an electronic device with a screen. The screen displays a display interface. In one example method, a current value of a current sampling point is obtained. Based on the current value, whether power consumption of the electronic device meets a criterion is determined. The display interface is adjusted when the power consumption of the electronic device does not meet the criterion.

  • Patent number: 10965798
    Abstract: A touchscreen includes a touch drive electrode, a touch sensing electrode, a touch drive circuit, a gate drive circuit, a touch drive electrode lead, and a liquid crystal panel. The touch drive electrode extends along a first direction. The touch drive circuit is disposed in a non-display area of the touchscreen, and an extension direction of the touch drive circuit is parallel to an extension direction of the touch drive electrode. The extension direction of the touch drive circuit is the same as the extension direction of the touch drive electrode. Each touch drive electrode is connected to the touch drive circuit using a touch drive electrode lead. The touch drive electrode lead is disposed in an area in which a gate drive circuit is located. The touch drive electrode lead and the gate drive circuit are disposed in an overlapping manner and are isolated from each other.

  • Patent number: 10955979
    Abstract: An array substrate including a display area and a non-display area, where the non-display area includes a first gate driving circuit, a second gate driving circuit, a first touch driving circuit and a second touch driving circuit. An extension direction of the first gate driving circuit and an extension direction of the second gate driving circuit are perpendicular to an extension direction of gate lines. An extension direction of the first touch driving circuit and an extension direction of the second touch driving circuit are perpendicular to an extension direction of touch driving electrodes. The first touch driving circuit and the first gate driving circuit are disposed in series along a same direction, and the second touch driving circuit and the second gate driving circuit are disposed in series along a same direction.

  • Patent number: 10460701
    Abstract: A display mura correction method includes: obtaining initial image data of an initial image displayed on a display of a terminal, where the initial image data includes image data of a mura region corresponding to the initial image, when at least one pixel whose brightness value is not in a reference threshold set exists in the initial image data, the mura region is a region that is covered by the at least one pixel on the display, and a target feature data set of the mura region includes a set of target feature data of the at least one pixel; obtaining, according to a correspondence between feature data and a correction value and the target feature data of the at least one pixel, a target correction value set corresponding to the target feature data set; and writing the target correction value set into the terminal.
