Pixel drive circuit, display panel, and display device

A display panel, comprising:

• a plurality of pixels, each pixel comprising a plurality of sub-pixel elements;
• and
• a pixel drive circuit, comprising:
• a drive circuitry, comprising:
• a drive transistor, having an input end, an output end, a first control end and a second control end, wherein the input end of the drive transistor is coupled to a drive-voltage terminal, and the output end of the drive transistor is coupled to one of the plurality of sub-pixel elements;
• and
• a storage capacitor, one end of the storage capacitor coupled to the drive-voltage terminal, and another end of the storage capacitor coupled to the output end of the drive transistor;
• a data-writing circuitry, an output end of the data-writing circuitry coupled to the first control end of the drive transistor, wherein the data-writing circuitry is configured to write a data voltage to the first control end of the drive transistor in a writing phase;
• and
• compensation circuitry comprising two compensation elements, wherein one of the two compensation elements is coupled between the output end and the first control end of the drive transistor to compensate a potential at the first control end of the drive transistor, and the other one of the two compensation elements is coupled between the output end and the second control end of the drive transistor, to compensate a potential at the second control end of the drive transistor.
