1. A processing method for pixel data, comprising:
determining a target pixel point in pixel points of a display frame image to be revised to prolong the lifetime of white sub-pixels, wherein a pixel data of each of the pixel points comprises S initial pixel data of different primary colors and a white initial pixel data, the S initial pixel data of different primary colors corresponds to S primary colors respectively, the white initial pixel data corresponds to white, and S is a positive integer;
converting only a white initial pixel data in a pixel data of the target pixel point into S equivalent pixel data of the different primary colors, wherein a brightness of the white initial pixel data in the pixel data of the target pixel point during display is the same as a brightness of the S equivalent pixel data of the different primary colors during display, a display effect of the white initial pixel data in the pixel data of the target pixel point during display is the same as a display effect of the S equivalent pixel data of the different primary colors during display, and the white initial pixel data in the pixel data of the target pixel point is not related to S initial pixel data of the different primary colors in the pixel data of the target pixel point; and
obtaining S target pixel data of the different primary colors and a white target pixel data of the target pixel point according to the S equivalent pixel data of the different primary colors and according to the S initial pixel data of the different primary colors in the pixel data of the target pixel point, wherein the white target pixel data corresponds to a 0 gray scale when the white initial pixel data corresponds to a non-zero gray scale,
wherein the obtaining the S target pixel data of the different primary colors and the white target pixel data of the target pixel point according to the S equivalent pixel data of the different primary colors and according to the S initial pixel data of the different primary colors in the pixel data of the target pixel point comprises:
superimposing the S equivalent pixel data of the different primary colors and the S initial pixel data of the different primary colors in the pixel data of the target pixel point respectively to obtain the S target pixel data of the different primary colors; and
determining the white target pixel data to be 0 gray scale.
