Abstract

The invention relates to the technical field of display, and provides a pixel driving circuit, a pixel structure and a display panel. The pixel driving circuit comprises a plurality of driving transistors, the first end of each driving transistor is connected with a first power supply end, the second end of each driving transistor is connected with a first node, the control end of each driving transistor is connected with a second node, and the driving transistors are used for inputting a current to the first nodes under the voltage effect of the second nodes. The pixel driving circuit can beapplied to the low-pixel-density area of the display panel, so that the brightness difference between the low-pixel-density area and the high-pixel-density area can be avoided.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a pixel driving circuit, a pixel structure and a display panel. Background technique [0002] In the related art, in order to realize a full-screen design of a display device such as a mobile phone, a camera of a display device such as a mobile phone is usually hidden in a display area of ​​a display panel. The pixel density of the display area where the camera is hidden needs to be set to be smaller than that of the normal display area to increase its light transmittance, which is beneficial for the camera to collect the light of the object to be photographed. [0003] However, since the low pixel density area where the camera is hidden and the normally displayed high pixel density area have different pixel densities, the high pixel density area and the low pixel density area will have different display brightness when the display panel displays images. [0004] It sho...
