Abstract

The present disclosure provides a display device and a display panel thereof, and a pixel drive circuit of a display panel. By changing a width-to-length ratio of a drive transistor in the pixel drive circuit of each sub-pixel, or changing a capacitance of a storage capacitor at the same time, such that: under the same gray scale, the width-to-length ratio of a drive transistor of each sub-pixel in same color is in direct proportion to a drive current; or at the same time a charging saturation of a storage capacitor of each sub-pixel in same color is the same, and the capacitance of the storage capacitor of each sub-pixel in same color is in direct proportion to the drive current, and the charging saturation is a difference value between an actual charging voltage and a theoretical charging voltage of the storage capacitor when a charging phase ends.
