Abstract
A display data processing method of a display device, a display device, an electronic device, and a storage medium are disclosed. The display data processing method includes: in response to a frequency of the dimming screen being consistent with a frequency of the display screen: determining a first gray-scale value of the first dimming pixel according to a plurality of input gray-scale values in an input image; determining a second gray-scale value of the first dimming pixel according to the first gray-scale value and a noise reduction function, where the noise reduction function is a monotonically increasing function in an interval (0, 1); obtaining a dimming gray-scale value of the first dimming pixel based on the second gray-scale value; and determining a plurality of target gray-scale values corresponding to the plurality of first display pixels according to the plurality of input gray-scale values and the dimming gray-scale value.
