Display panel and display device

Abstract

The invention discloses a display panel and a display device, comprising: a display area and a non-display area arranged around the display area; the non-display area includes a first binding area and a second binding area; the first binding area includes at least one The output unit, the output unit includes a first pad group and a second pad group, the first pad group and the second pad group are arranged along the first direction, and each includes a plurality of first pad groups arranged along the second direction. An output pad and a plurality of second output pads; the first output pad and the second output pad are arranged in different layers; in the first pad group, at least two adjacent first output pads are arranged between two second output pads; in the second pad group, at least two first output pads are arranged between two adjacent second output pads. Compared with the prior art, it is more convenient to count the output pads during the mirror inspection operation, which is beneficial to improve the detection accuracy of abnormal pads.

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 ...

[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.
