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.

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.

Abstract: An electronic device includes at least a battery, a working circuit, and a boost circuit. When the battery supplies power to the working circuit, the boost circuit supplies power to the working circuit in response to that the electronic device meets a low-temperature or low-voltage condition. In a power supply path switching process, the boost circuit first supplies power to the working circuit through a diode, and then disconnects a path for supplying power to the working circuit by the battery. Before the path for supplying power to the working circuit by the battery is disconnected, a voltage for supplying power to the working circuit by the boost circuit through the diode is controlled not to be higher than a voltage for supplying power to the working circuit by the battery.
