    摘要: The present disclosure provides a voltage driving method and device for a touch display panel, and a touch display panel, which includes a common electrode extending in a first direction and a plurality of columns of touch electrodes extending parallel to each other in a second direction. The voltage driving method includes: applying a first scanning voltage to two outermost columns of touch electrodes during a first period of a first touch cycle including a plurality of periods, the first scanning voltage being equal to a reference voltage; detecting a first output voltage output by the two outermost columns of touch electrodes during the first period; and adjusting, based on the detected first output voltage, the scanning voltage applied to the two outermost columns of touch electrodes during a first period of a second touch cycle immediately after the first touch cycle, to a second scanning voltage.

    摘要: The present disclosure relates to a data transmission method and device, a display screen, and a display device, and belongs to the application field of display technology. The method is applicable to a first drive chip in a display device that includes a controller, a plurality of drive chips and a data acquisition apparatus. The first drive chip is one of the plurality of drive chips and connected to the controller and the data acquisition apparatus respectively. The method includes: receiving component-related data acquired by the data acquisition apparatus; and sending backhaul data to the controller, the backhaul data including the component-related data. The present disclosure solves the problem of function singleness of the drive chip. The present disclosure is applicable to drive and control the display device.

    摘要: The present disclosure relates to a signal detection method and component, as well as a display device. The display device includes a timing controller and a source driver. The source driver receives a test code stream from the timing controller, which is obtained through encoding of an initial code stream by the timing controller, the initial code stream representing a test signal. The source driver decodes the test code stream. When the decoded code stream is different from the initial code stream, configuration information of the source driver is acquired. The configuration information is transmitted to the timing controller, and is adjusted according to reference information of the timing controller when it does not match with the reference information. The source driver receives adjusted configuration information transmitted by the timing controller, and then receives a subsequently transmitted signal according to the adjusted configuration information.
