The present invention relates to the field of display technology, and proposes a pixel driving circuit, a driving method thereof, and a display panel. The pixel driving circuit includes a data writing circuit, a driving circuit, a lighting control circuit, a compensation circuit, and a storage circuit; the data writing circuit is coupled to The drive circuit is used to write data signals to the drive circuit; the drive circuit is coupled to the first power supply terminal and the light-emitting unit through the light-emitting control circuit, and is used to input drive current to the light-emitting unit according to the data signal under the control of the light-emitting control circuit; the compensation circuit Coupled to the driving circuit; the storage circuit is coupled between the first power supply terminal and the driving circuit; the data writing circuit and the compensation circuit include at least two transistors, wherein, in the data writing circuit and the compensation circuit, at least one transistor is low temperature Polysilicon transistors, at least one transistor is an oxide transistor. The pixel driving circuit is beneficial to realize a display panel with high pixel density and has a small leakage current.
Description
technical field [0001] The present invention relates to the field of display technology, in particular to a pixel driving circuit, a driving method thereof, and a display panel. Background technique [0002] The pixel driving circuit is used to drive the light-emitting unit in the pixel unit to emit light. In the related art, the pixel driving circuit needs to be connected with a plurality of signal lines, so as to provide signals to each signal terminal of the pixel driving circuit through the signal lines. However, due to the large number of signal lines in the pixel driving circuit, it is not conducive to the manufacture of high pixel density display panels. [0003] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present invention, and therefore may include information that does not constitute prior art known to those of ordinary skill in the art.
