Abstract

The invention provides a pixel driving circuit, a display device and a driving method of the pixel driving circuit, which solve the technical problem that the luminance of each pixel is inconsistent due to incomplete data writing in the prior art. The pixel driving circuit provided by the embodiment of the invention adopts an additional capacitor and two drive transistors. In the data writing phase when the pixel driving circuit operates, the two drive transistors are connected in parallel, data signal voltage is written into a data storage module through the two drive transistors, which greatly increases the writing speed of the data signal voltage and greatly reduces voltage attenuation of the data signal during the write-in process. Thereby, voltage error at the output end of a light-emitting drive module is small, and then the influence of the error voltage on brightness of the pixel is reduced.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a pixel driving circuit, a display device and a driving method for the pixel driving circuit. Background technique [0002] In the prior art, when the display device requires a higher pixel resolution, the writing time of the data signal of each pixel during the actual working process of the pixel driving circuit is relatively short, resulting in incomplete writing of the data signal and As a result, there is a certain error in the gate voltage of the driving transistor, which in turn causes a certain error in the driving current, so that the luminance of each pixel is inconsistent. Contents of the invention [0003] In view of this, the embodiment of the present invention provides a pixel driving circuit, a display device, and a driving method of the pixel driving circuit, which solves the technical problem of inconsistent luminance of each pixel caused by incomplete ...
