Abstract

The present invention provides a display device, including a display panel, a touch layer, a detection circuit and connecting wires. The display panel includes a display area and an electronic component installation area corresponding to the electronic component installation position. The electronic component installation area includes a first through hole and A buffer zone, the buffer zone surrounds the first through hole and is in contact with the display area; the touch layer is formed with a touch electrode, and the touch layer is formed with a second through hole in the area corresponding to the first through hole; the detection circuit is arranged in the buffer area The area is used to detect the quality of the first through hole in the display panel; the connection line is formed in the touch layer and used to connect the detection circuit and the peripheral circuit. By designing a detection circuit that introduces the peripheral circuit into the interior from the touch layer, the quality of the hole-digging part of the display panel is inspected, and the damage and cracks at the hole-digging part can be detected in time to avoid the failure of the display device from entering the display panel. Subsequent process flow improves product yield.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display device. Background technique [0002] With the development of full-screen technology, it is a development trend to place electronic components such as cameras under the screen under the display screen, and the corresponding display screen needs to be designed with holes. However, destructive defects such as breakage and cracks may occur in the hole-digging area, resulting in screen failure. If it directly enters the subsequent process, it will affect the product yield. [0003] Therefore, the existing display panel has the technical problem that the quality of the hole-digging area needs to be detected, which needs to be improved. Contents of the invention [0004] The invention provides a display device to alleviate the existing technical problem that the quality of the hole-digging area needs to be detected. [0005] In order to solve the above problems, ...
