Example Embodiment

[0040] Example one

[0041] The structure of a display panel provided by the first embodiment of the present invention, such as figure 2 As shown, it includes a display area 201 and a non-display area 202 surrounding the display area. A metal wire 203 is arranged in the non-display area 202 to form two layers of crack detection wires surrounding the display area 201.

[0042] Preferably, the start and end of the metal wire 203 are located on the same side of the display panel; for example, figure 2 As shown, the start and end of the metal wire 203 are both located on the side of the lower end of the display panel.

[0043] An intersection between the inner and outer layers of crack detection wires formed by the metal wire 203 is located on the other side opposite to the side. For example, such as figure 2 As shown, an intersection between the inner and outer layers of crack detection wires formed by the metal wire 203 is located in the middle of the side of the upper end of the di...

Example Embodiment

[0051] Example two

[0052] The structure of a display panel provided by the second embodiment of the present invention, such as image 3 As shown, it includes a display area 301 and a non-display area 302 surrounding the display area. Two metal wires are arranged in the non-display area 302. The first metal wire 311 is formed in the non-display area on the left. The inner and outer layers of crack detection wires surround the left display area; the second metal wire 312 forms the inner and outer layers of crack detection wires surrounding the right display area in the non-display area on the right.

[0053] Preferably, as image 3 As shown, the start and end of the first metal line 311 are located on the same side of the display panel, and the start of the first metal line 311 is located in the outer layer, that is, the start of the first metal line 311 is an outer layer crack Detection wire; the bend between the inner and outer crack detection wires formed by the first metal wire...

Example Embodiment

[0063] Example three

[0064] The structure of a display panel provided by the third embodiment of the present invention, such as Figure 4 As shown, it includes a display area 401 and a non-display area 402 surrounding the display area. Two metal wires are arranged in the non-display area 402. The first metal wire 411 is formed in the non-display area on the left. The inner and outer layers of crack detection wires surround the left display area; the second metal wire 412 forms the inner and outer layers of crack detection wires surrounding the right display area in the non-display area on the right.

[0065] Preferably, as Figure 4 As shown, the start and end of the first metal line 411 are located on the same side of the display panel, and the start of the first metal line 411 is located in the outer layer, that is, the start of the first metal line 411 is an outer layer crack Detection wire; the bend between the inner and outer crack detection wires formed by the first metal...

Abstract

The invention discloses a display panel and a display apparatus. The display panel comprises a display region and a non-display region around the display region; at least one metal wire is distributedin the non-display region to form inner and outer layer crack detection wires around the display region, wherein the inner and outer layer crack detection wires in parallel and positioned on the sameside of the display panel are formed by the same metal wire; and the inner and outer layer crack detection wires formed by the same metal wire have a bending position or a crossed position therebetween. By applying the display panel, the crack detection rate of the display panel can be improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] In recent years, mobile display technology has developed rapidly, and the new generation of display technology represented by flexible display is being more and more widely used. However, in the back-end process of cutting the flexible display panel, the edge of the panel is very prone to tiny cracks. Since flexible displays generally use organic light-emitting diode technology, organic light-emitting diodes have high requirements for packaging technology. Once tiny cracks appear on the edge of the panel, water vapor can easily penetrate into the panel, resulting in the failure of the organic light-emitting material and shortening the life. Therefore, How to monitor the tiny cracks around the panel has become a very important issue. [0003] figure 1 It is an existing display panel crack detection met...
