Abstract

The present application provides a pixel driving circuit and a display device, wherein the pixel driving circuit is used to provide signals to elements to be driven, and the pixel driving circuit includes a current control module, a duration control module and an output module; the current control module is configured to transmit current signals; The duration control module is configured to transmit a time signal; the output module is electrically connected to the duration control module and the current control module; the duration control module is also configured to control the on and off of the output module according to the time signal; the output module is configured to , to control the current of the driving element according to the current signal; the duration of two adjacent conductions of the output module is the same, and the duration of the interval between two adjacent conductions is the same. Through the above setting, it is ensured that the elements to be driven are periodically turned on in each frame, and the phenomenon of flickering of the elements to be driven when turned on is reduced or avoided.

Description

technical field [0001] The present application relates to the display field, in particular to a pixel driving circuit and a display device. Background technique [0002] Micro-inorganic light-emitting diodes are usually used in display devices because of their advantages such as high brightness, long life, and small size, and have broad development prospects in the display field. However, in some scenarios, the miniature inorganic light emitting diodes in such a display device, for example, when the miniature inorganic light emitting diodes are performing low grayscale (ie low brightness) display, the total time of the light emitting diodes emitting light in one frame is longer Short, and uneven distribution of luminous time, there will be flickering phenomenon. Contents of the invention [0003] The present application provides a pixel driving circuit and a display device, which can reduce or avoid flickering of elements to be driven. [0004] According to the first asp...
