Abstract

The invention discloses a pixel driving circuit, a driving method of the pixel driving circuit and a display panel. The pixel driving circuit includes a driving module, a first voltage input module, a compensation module, a data writing module, a storage module, a light-emitting control module and a light-emitting module; the first voltage input module is used for writing a first voltage to the driving module; the compensation module used to perform threshold compensation on the first voltage; the data writing module is used to write the data voltage to the storage module; the storage module is used to maintain the data voltage; the driving module is used to output the driving signal according to the data voltage; the lighting control module is used to control the storage The module couples the data voltage to the driving module, and controls the driving signal to be output to the light-emitting module, and controls the light-emitting module to emit light. The influence of the threshold voltage compensation time on the resolution and refresh frequency of the display panel can be reduced, the compensation effect of the threshold voltage is ensured, and the brightness uniformity of the display panel is improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular, to a pixel driving circuit, a driving method for the pixel driving circuit, and a display panel. Background technique [0002] The pixel driving circuit in the display panel includes driving transistors. Due to differences in the characteristics of the driving transistors corresponding to different sub-pixels on the display panel, it is easy to cause uneven display of the display panel. In the prior art, a threshold compensation transistor is added to the pixel driving circuit for compensating the threshold voltage of the driving transistor, thereby improving the display uniformity of the display panel. During the compensation process, the time period for compensating the threshold voltage of the driving transistor is easily affected by the refresh frequency and resolution of the display panel, resulting in a contradiction between the threshold voltage co...
