Abstract: A display device and an overdrive method thereof are provided. The overdrive method includes that in a frame picture, when a data signal of a data line needs to be switched from a grayscale of a previous row to a target grayscale of a current row, a feedback grayscale is looked up to be obtained according to a default feedback lookup table, the target grayscale of the current row, and an input grayscale of the previous row, a gain grayscale is looked up to be obtained according to a default gain lookup table and the feedback grayscale, and the gain grayscale is stored into a row buffer.

Abstract: A spliced display panel and a method of compensating the spliced display panel for a mura phenomenon are disclosed. In the method, secondary compensation values are obtained through a secondary compensation formula and initial compensation values in order to compensate spliced regions of the spliced display panel for the second time.

Abstract: The present invention provides a display device. The display device includes a timing controller, a data register, a source driver, and a display panel. A portion of a vertical effective display column data in a vertical idle period is output through the data register, which can increase a sum of charging time of a pixel column of an entire frame of images. Moreover, an N/2th horizontal idle period to the Nth horizontal idle period are adjusted to improve display uniformity of an upper half screen and a lower half screen.

Abstract: The present application provides a display panel adjustment method and an adjustment method for a display panel. A fan-out mura region of the display panel is divided into multiple first sub-regions along a first direction; according to an initial grayscale value of a first bonding point in the first sub-region, the fan-out mura degree and a first correction value of the corresponding first sub-region are obtained; and then grayscale compensation is performed on the corresponding first sub-region. The present application improves the mura effects in the fan-out region and improves the display quality of a product.
