Embodiment Construction
[0046] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0047] At present, the edge area of some flexible display panels (such as organic light-emitting diode (English: Organic Light-Emitting Diode; abbreviation: OLED) display panel) can usually be used for bending, such as some curved screen mobile phones. A screen whose edges are usually curved. Therefore, in the related art, a detection line (the detection line may be referred to as a Panel Crack Detect (English: Panel Crack Detect; PCD for short) line) is usually provided in the edge region. Exemplary, such as figure 1 As shown, the edge area b of the display panel may be an area where the edge of the display panel extends to the center for a specified distance, and other areas except the edge area b may be the middle area z. A dete...

The invention discloses a display panel and a display panel detecting method, and belongs to the technical field of the display. The display panel comprises a substrate base plate, an edge detecting line, and a middle detecting line, wherein the edge detecting line comprises at least one sub-edge line located at an edge region of the substrate base plate; and the middle detecting line comprises atleast one sub-middle line located at other areas of the substrate base plate except the edge area. In at least one of the sub-middle lines, two ends of any sub-middle line are not connected. According to the display panel and the display panel detecting method, the middle detecting lines are provided in other areas except the edge area in the substrate base plate to detect whether there is a crack in the display panel other than the edge area, then the edge detecting lines in the edge area are cooperated to detect whether there is a crack in the edge area, and the display panel is relativelycomprehensively detected. The problem of the display panel in which the crack may be missed in the related art is solved. The effect of avoiding the detection of a cracked display panel is achieved.
Description
technical field [0001] The invention relates to the field of display technology, in particular to a display substrate and a crack detection method for the display substrate. Background technique [0002] During the manufacturing process of the display panel, tiny cracks may occur due to various reasons. In order to prevent such cracked display panels from entering the market, the display panel is usually tested for cracks. [0003] In a display panel in the related art, a circle of detection lines with an opening is arranged on its edge, and an external detection signal is used to input a signal from one end of the opening, and the detection is determined according to whether the other end of the opening receives an output signal. Whether the line is cut off by a crack in the display panel. [0004] In the process of realizing the present invention, the inventors found that the related technology has at least the following problems: the detection of cracks in the above-men...
