Abstract

The invention discloses a pixel driving circuit, a driving method thereof and a display device, and relates to the technical field of display, in the same time frame, the pixel driving circuit comprises a non-light-emitting stage and a light-emitting stage; the pixel driving circuit comprises a first frequency driving mode and a second frequency driving mode, and the first frequency is greater than the second frequency; signals received by the pixel driving circuit comprise a first control signal, and in a first frequency driving mode, the pulse variation of the first control signal is delta V1 from a non-light-emitting stage to a light-emitting stage; in the second frequency driving mode, the pulse variation of the first control signal is delta V2 from the non-light-emitting stage to thelight-emitting stage, and delta V2 is larger than delta V1. Thus, the possibility that the brightness of the display device suddenly changes when the first frequency driving mode and the second frequency driving mode are switched can be reduced, and therefore the brightness transition effect of the display device during switching of the two driving modes can be improved.

Description

technical field [0001] The present application relates to the field of display technology, and more specifically, to a pixel driving circuit, a detection method thereof, and a display device. Background technique [0002] Organic light-emitting display devices have the advantages of self-luminescence, low driving voltage, high luminous efficiency, fast response speed, thinness, and high contrast, and are considered to be the most promising display devices for the next generation. Organic light-emitting display devices are more and more widely used in other display devices with display functions such as mobile phones, computers, televisions, vehicle-mounted display devices, or wearable devices. [0003] A pixel in an organic light-emitting display device includes a pixel driving circuit, the driving transistor in the pixel driving circuit can generate a driving current, and the light-emitting element emits light in response to the driving current, wherein the driving current ...
