Abstract

The invention discloses a display panel, a preparation method thereof and a display device, which are used for avoiding failure of a crack detection function. The display panel provided by one embodiment of the invention is provided with an open hole area, a display area surrounding the open hole area and a blocking area located between the display area and the open hole area. The display panel comprises a first retaining wall which is located in the blocking area and surrounds the opening area, a second retaining wall which is located on the side, close to the opening area, of the first retaining wall and surrounds the opening area, a heightening layer which is located between the first retaining wall and the second retaining wall, a crack detection line which is positioned on one side, close to the opening area, of the second retaining wall, and at least two connecting leads which are used for leading the crack detection line to the display area through the blocking area; in the direction perpendicular to the plane where the display panel is located, the orthographic projection of the area between the connecting leads and the orthographic projection of the heightening layer are overlapped.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display panel, a manufacturing method thereof, and a display device. Background technique [0002] At present, almost all mobile phone cameras on the market are placed above the screen. Because the camera has a certain size, it often occupies a large frame on the whole phone, which seriously affects the screen-to-body ratio. As the mobile phone market favors full-screen mobile phones, products with AA holes in the display area and cameras placed in the hole area have been born, and have been highly sought after in recent years. [0003] However, the technical development of punching holes in the display area faces various problems. For example, when cutting the display area, it is easy to generate crack cracks, and the cracks are easy to extend to the effective display area in the subsequent process, causing package failure and reducing the reliability of display pr...
