    Abstract: 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.

    Abstract: Embodiments of the present disclosure provide a method of driving display, and a display device. The method of driving display includes: scanning, progressively or rows by rows, a plurality of sub-pixels arranged in an N×M array, to turn on each row of sub-pixels scanned, so that a duration in which two adjacent rows of sub-pixels are simultaneously in an ON state is greater than or equal to two times a unit scanning time, wherein the unit scanning time is a time required for scanning a row of sub-pixels, N is an integer greater than 1, and M is an integer greater than 1; and applying data signals to at least two rows of sub-pixels simultaneously in the ON state, so that a duration of applying the data signals to each row of sub-pixels is greater than the unit scanning time.
