Description
technical field [0001] The present invention relates to the technical field of pixel driving, in particular to a pixel driving circuit, a driving method, a pixel unit and a display device. Background technique [0002] Due to process deviation, the threshold voltage of the driving TFT (Thin Film Transistor, thin film transistor) in the pixel driving circuit included in the display device will shift, resulting in non-uniform driving current of different pixels. Existing pixel drive circuits cannot save space for circuit design while eliminating threshold voltage deviations caused by process deviations. Therefore, they cannot increase the pixel aperture ratio, reduce the number of circuit signal lines, reduce circuit costs, and facilitate circuit design. Contents of the invention [0003] The main purpose of the present invention is to provide a pixel driving circuit, a driving method, a pixel unit and a display device, so as to solve the problem that the existing pixel driv...
