Abstract

The invention discloses a pixel driving circuit, a driving method thereof and a display device, and relates to the technical field of display. The pixel driving circuit comprises a driving transistorconnected in series with the organic light emitting element; a first reset module which is electrically connected with the grid electrode of the driving transistor; a data writing module which is electrically connected with the driving transistor; a light-emitting control module which is electrically connected with the first electrode of the organic light-emitting element; and a holding module, wherein a first electrode of the holding module is electrically connected with the first electrode of the organic light-emitting element, and the second electrode of the holding module is electrically connected with the first fixed potential, so the target potential is kept stable after the potential of the first electrode of the organic light-emitting element reaches the target potential. The problem that in the prior art, wiring electrically connected with an organic light-emitting element in a pixel driving circuit affects the potential of a grid electrode of a driving transistor and affectsthe display effect of a display device is solved.

Description

technical field [0001] The present invention relates to the field of display technology, and more specifically, to a pixel driving circuit, a driving method thereof, and a display device. Background technique [0002] In the process of constantly pursuing the large screen-to-body ratio of the terminal, people put forward the concept of "full screen". The current full-screen display device refers to a display device with a screen-to-body ratio of more than 90% and an ultra-narrow bezel design. Display devices in the prior art are usually equipped with devices such as cameras and photoelectric sensors in order to meet the diverse needs of users. [0003] The full screen means that there is no longer a special space on the front of the terminal for setting the front camera, earpiece and other devices. Therefore, the "under-screen camera" came into being. The so-called under-screen camera refers to setting the front camera under the screen. In order to improve the transmittan...
