    摘要: A driver, a display device, and an optical compensation method thereof are provided. The display panel includes sub-pixels arranged in an array. The method includes: receiving an initial gray level of each sub-pixel of a picture to be displayed; determining whether each sub-pixel satisfies a preset determination condition based on the initial gray level of each sub-pixel; if an absolute value of a difference between the initial gray levels of two sub-pixels electrically connected to a same data line and located in two adjacent rows is greater than a preset threshold, it is determined that a sub-pixel in a next row satisfies the preset determination condition; and, in response to determining that a sub-pixel satisfies the preset determination condition, acquiring a first compensation parameter of the sub-pixel, and compensating the initial gray level of the sub-pixel based on the acquired first compensation parameter.

    摘要: The present disclosure provides a display apparatus, a display panel, and a method of driving a display panel. The display panel includes: a base substrate; a pixel array disposed on the base substrate, and including one or more pixel groups each of which includes a plurality of pixels; and a plurality of pixel driving chips disposed on the base substrate and configured to drive the pixel array to display, each of the pixel driving chips including a data signal terminal for receiving data signals and a control signal terminal, where for each of the pixel groups, the plurality of pixels in the pixel group are connected to a common pixel driving chip. A display frame of the display panel includes an address assignment stage and a data signal transmission stage. The method includes: inputting the control signal to the control signal terminal and inputting a first data signal to the data signal terminal in the address assignment stage; and inputting a second data signal to the data signal terminal in the data signal transmission stage. The present disclosure can reduce the number of signal lines and reduce power consumption.
