Problems solved by technology

[0004] However, when microscopically inspecting the bonding pads for short circuits and foreign matter defects, it is often necessary to increase the magnification of the microscope, and when counting the bonding pads to determine the location of the abnormality, the magnification of the microscope has to be lowered , otherwise the number of bonded pads in the same field of view is small, which is not conducive to counting. Switching the magnification back and forth in this way makes the mirror inspection process time-consuming and laborious, and it is difficult to improve the production efficiency of the display device.

Abstract

The invention discloses a display panel and a display device. The display panel comprises a display area and a non-display area arranged around the display area, wherein the non-display area includesa first binding area and a second binding area; the first binding area includes at least one output unit, the output unit includes a first bonding pad group and a second bonding pad group, the first bonding pad group and the second bonding pad group are arranged in a first direction, and both the first bonding pad group and the second bonding pad group include a plurality of first output bonding pads and a plurality of second output bonding pads which are arranged in a second direction; the first output bonding pads and the second output bonding pads are arranged in different layers; in the first bonding pad group, two adjacent first output bonding pads are provided with at least two second output bonding pads therebetween, and in the second bonding pad group, two adjacent second output bonding pads are provided with at least two first output bonding pads therebetween. Compared with the prior art, the output bonding pads can be counted more conveniently when microscopic examination iscarried out, thereby being conducive to improving the abnormal bonding pad detection accuracy.

Description

technical field [0001] The present invention relates to the field of display technology, and more particularly, to a display panel and a display device. Background technique [0002] With the continuous development of display technology, the display screen has gradually developed from the original cathode ray tube (Cathode Ray Tube, CRT) display to the popular liquid crystal display (Liquid Crystal Display, LCD) and organic light emitting display (Organic Light Display) in recent years. Emitting Diode, OLED) and so on. At the same time, with people's continuous pursuit of visual effects, continuously narrowing the frame of the display screen and increasing its screen-to-body ratio has become an important research direction of the current display technology. [0003] Due to the narrowing of the frame of the display screen, the size of the driving module used to drive the screen display of the display screen needs to be continuously reduced, and even integrated into the same ...
