Abstract

The embodiment of the invention provides a pixel driving circuit, a driving method of the pixel driving circuit and a display device, and solves the technical problem that a certain error exists in agate voltage of a driving transistor due to incomplete writing of a data signal in the prior art. According to the pixel driving circuit provided by the embodiment of the invention, when a data signalvoltage is transmitted to a data storage module, a starting point voltage of the discharge of the data storage module is increased by adopting the gate-drain short circuit of a compensation module and a second driving transistor. Therefore, the discharge time of the data storage module is shortened, the data signal writing time is shortened, the data signal writing speed is increased, the attenuation of the data signal during writing is reduced, the error voltage is reduced, the difference of a driving current is reduced, and the probability of inconsistent pixel brightness 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] When the display device requires a higher pixel resolution, in the actual working process of the pixel driving circuit in the prior art, the writing time of the data signal of each pixel is relatively short during the working process, resulting in incomplete writing of the data signal 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 for the pixel driving circuit, which solves the problem that the gate voltage of the driving transistor has...
