This application is a National Phase of PCT Patent Application No. PCT/CN2020/082692 having International filing date of Apr. 1, 2020, which claims the benefit of priority of Chinese Patent Application No. 202010147355.9 filed on Mar. 5, 2020. The contents of the above applications are all incorporated by reference as if fully set forth herein in their entirety.
The present disclosure relates to a technical field of display, and particularly to a display panel.
Organic light-emitting diodes (OLEDs) are more widely used due to their advantages of light weight, self-illumination, wide viewing angles, low driving voltage, high luminous efficiency, low power consumption, and fast response times. Full screen is one of goals of development of OLED display technology, which can be achieved by digging a hole in a screen and installing a camera device in the hole. However, after digging the hole in the screen, array wires need to bypass the hole to work properly. Due to many wires involved, a width of a wiring area around the camera is relatively large, which greatly reduces a screen ratio of a full screen. Moreover, difference in resistance between different metal layers is large, which may cause abnormal display.
Therefore, the current technology has defects and needs to be improved urgently.
The present disclosure provides a display panel configured to improve a wiring distribution in an area around a front camera to reduce a width of a wiring area, so as to solve the problem that an area occupied by a camera is too large in the prior art.
