    Abstract: A display driving method includes: controlling a source driver to output a data signal, wherein the data signal comprises a plurality of first active pulse signals, the first active pulse signal in the Nth row is for driving a sub-pixel unit in the Nth row, and a timing difference between a starting point of the first active pulse signal in the Nth row and a starting point of a corresponding gate drive signal is smaller than a timing difference between a starting point of the first active pulse signal in the (N+M)th row and a starting point of a corresponding gate drive signal; and wherein the sub-pixel unit in the Nth row is closer to the source driver than the sub-pixel unit in the (N+M)th row, and N and M are positive integers greater than or equal to 1.

    Abstract: A data signal delay circuit and delay method and a display device are disclosed. The data signal delay circuit includes a feedback signal generation sub-circuit, a compensation signal generation sub-circuit, and a control sub-circuit. The feedback signal generation sub-circuit is configured to generate a feedback signal based on a first level signal from the first level signal terminal and a second level signal from the second level signal terminal under the control of a gate drive signal from a scan signal line currently being scanned. The compensation signal generation sub-circuit is configured to generate a compensation signal based on the feedback signal and a data enable signal from the data enable signal line. The control sub-circuit is configured to delay a data enable signal of the data enable signal line in a next cycle based on the compensation signal.

    Abstract: A driving chip for a display panel is provided. The display panel includes a plurality of subpixels arranged at a display region, the display region is provided with a boundary extended by a non-straight line, and the plurality of subpixels includes first subpixels separated from the boundary by a distance substantially smaller than a predetermined threshold and second subpixels other than the first subpixels. The driving chip includes: an adjustment circuit configured to, when the display panel is in a predetermined display mode, adjust a first grayscale value of at least a part of the first subpixels in original image data into a second grayscale value substantially smaller than the first grayscale value; a driving circuit configured to drive the at least a part of first subpixels in accordance with the second grayscale value to display an image.
