    摘要: A method and a device for compensating for image crosstalk and a display apparatus are provided. The method includes: obtaining (S101) a data-voltage variation value between a data voltage applied to a pixel unit at a current scanning time instant and a data voltage applied to the pixel unit at a previous scanning time instant; determining a power-voltage variation value based on the data-voltage variation value (S102); setting a sum of the power-voltage variation value and an original data voltage to be applied to the pixel unit at a next time instant as a compensated data voltage of the pixel unit (S103); and setting the compensated data voltage of the pixel unit as an actual data voltage to be applied to the pixel unit at the next time instant (S104).

    摘要: A gray-level compensation method and apparatus, a display device and a computer storage medium are provided, which belong to the field of display technology. The method includes: acquiring an initial gray-level value of a target pixel; determining an actual luminance offset of the target pixel based on the initial gray-level value, where different initial gray-level values within a specified threshold range correspond to different actual luminance offsets; and performing a gray-level compensation on the target pixel based on the actual luminance offset. The actual luminance offset is determined based on the initial gray-level value of the target pixel, and since the different initial gray-level values within the specified threshold range correspond to the different actual luminance offsets, flexibility of gray-level compensation performed on the pixel is improved.

    摘要: Embodiments of the present disclosure provide gamma correction method and device for a display module. The gamma correction method includes: determining, for each sub-pixel of a display module to be corrected, the highest data voltage and the lowest data voltage after gamma correction of the highest gray scale and the lowest gray scale of the display module; determining at least one set of alternative gamma register values that are capable of performing gamma correction of the display module; determining at least one set of gamma register values to be corrected for respective gray scales before the gamma correction of the display module; and performing gamma correction of the display module by adjusting the gamma register value corresponding to the gray scale to be corrected which needs to perform gamma correction.

    摘要: Embodiments of the present disclosure provide a display panel and a drive method thereof, and a display device. The display panel includes a plurality of sets of pixel columns and a plurality of drive circuits. Each of the sets of pixel columns includes a plurality of subpixel columns. The plurality of drive circuits correspond to the plurality of sets of pixel columns respectively. Each of the drive circuits is further configured to send, to an adjacent drive circuit, a source data signal for the subpixel column in the set of pixel columns of the drive circuit, and/or receive, from the adjacent drive circuit, a source data signal for the subpixel column in the set of pixel columns of the adjacent drive circuit and generate a data signal for driving the subpixel column in the set of pixel columns of the drive circuit, based on the received source data signal.
