Embodiment Construction

[0045] As mentioned in the background art, the display panel in the related art has the problem of low crack detection accuracy. The inventors found that the reason for this problem is that the crack detection line arranged in the display panel surrounds the opening area to form a The crack detection ring, the crack detection ring has a gap, which makes the crack detection ring have a detection blind area. The specific analysis is as follows:

[0046] refer to figure 1 , when the crack detection ring includes a ring, the two ends of the ring are formed as figure 1 The notch 300 is shown. When the crack 500 appears in the gap 300, the crack detection ring will not be affected by the crack 500, that is, it is difficult to detect the crack 500 in this area, resulting in low accuracy of crack detection.

[0047] refer to figure 2 , when the crack detection ring includes two rings, the two rings are the inner ring and the outer ring respectively, and the connecting line between...

Abstract

The invention provides a display panel and a display device, relates to the technical field of display. The display panel is used for solving the technical problem that the crack detection accuracy of the display panel is relatively low. The display panel is provided with an opening area and a crack detection ring arranged along the circumferential edge of the opening area, the crack detection ring is provided with a notch enabling the crack detection ring to be disconnected, the first end of the notch is provided with an accommodating area, the second end of the notch is provided with a protruding part, at least part of the protruding part is located in the accommodating area, and the accommodating area is meshed with the protruding part. And a preset gap exists between the two gaps, so that cracks extending in one direction are difficult to pass through the gaps, missing detection is avoided, and the accuracy of crack detection is improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] With the development of display technology, hardware such as a camera module is usually integrated on the display panel, so as to obtain images by using the camera module. In the related art, an opening area is usually provided on the display panel, and a camera module is placed in the opening area. However, cracks are likely to appear on the edge of the opening area, and the cracks tend to extend to the non-opening area of ​​the display panel, which affects the normal display of the display panel. In order to ensure the normal use of the display panel, a crack detection (Panel Crack Detection, PCD for short) line surrounding the opening area is arranged in the display panel to detect whether there is a crack in the display panel. However, the crack detection line in the related art has detection bli...
