Abstract

The invention discloses a pixel driving circuit, a driving method thereof, and a display panel. The first end of the first initialization module of the pixel driving circuit is electrically connected to the initialization signal end, the second end is electrically connected to the first end of the storage module, and the control end is electrically connected to the first scanning signal end; the second initialization module The first end is electrically connected to the second end of the first initialization module, and the control end is electrically connected to the second scan signal end; the first end of the data writing module is electrically connected to the data signal end, and the second end is electrically connected to the drive module. The control terminal is electrically connected to the second terminal of the second initialization module, and the control terminal is electrically connected to the second scanning signal terminal; the lighting control module is connected between the second terminal of the storage module and the first power supply terminal, and the control terminal is connected to the user The energy signal terminal is electrically connected; the control terminal of the threshold compensation module is electrically connected to the third scanning signal terminal, and the second terminal of the light emitting module is electrically connected to the second power supply terminal. In the embodiment of the present invention, the driving current has nothing to do with the threshold voltage.

Description

technical field [0001] Embodiments of the present invention relate to display technologies, and in particular to a pixel driving circuit, a driving method thereof, and a display panel. Background technique [0002] With the development of the display technology, the application of the display panel is more and more extensive, and correspondingly, the requirement for the display panel is also higher and higher. [0003] Existing display panels generally drive light-emitting units to emit light through a pixel driving circuit. However, the existing pixel driving circuit may have a problem of threshold voltage drift, which affects the display effect. Contents of the invention [0004] The invention provides a pixel driving circuit, a driving method thereof, and a display panel. The driving current of a driving module in the pixel driving circuit has nothing to do with the threshold voltage of the driving module. [0005] In the first aspect, an embodiment of the present inve...
