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.
