Problems solved by technology

[0004] like figure 1 As shown, it is a schematic diagram of the anti-crack line structure of the existing panel. Since the anti-crack line 91 is a large piece of metal, it is connected to each other in the form of a fence and surrounds the panel. When performing electrostatic tests on products, the anti-crack line 91 is more likely to be damaged and transmits the charge to the working line 93 inside the panel, causing the panel to fail to work normally

Embodiment 1

[0034] see Figure 2-Figure 4 As shown, the first embodiment of the present invention provides a display panel 100, including a functional area 10 and a peripheral area 20 surrounding the functional area 10; wherein, a peripheral working circuit 30 is provided in the functional area 10, and the peripheral The working circuit 30 is adjacent to the peripheral area 20; the peripheral area 20 includes an anti-crack line 40 surrounding the functional area 10, and the anti-crack line 40 includes a plurality of parallel lines extending along the side of the functional area 10. Barrier strips 1 are arranged, and each of the barrier strips 1 has protruding structures 2 arranged at intervals.

[0035] During the electrostatic test of the display panel 100, due to the principle of tip discharge, the raised structure 2 is used to accumulate charges, and the charges will be gathered near the raised structure 2, which is easy to be injured; due to the anti-crack circuit 40 has no function ...

Embodiment 2

[0047] see Figure 5 As shown, in the second embodiment of the present invention, the protruding structure 2 is semicircular. It differs from the first embodiment in that only the protruding structure 2 is changed from a triangle shape to a semicircle shape.

[0048] see Figure 6 shown, for Figure 5 The schematic diagram of force analysis of the anti-crack circuit 40 in , since the raised structure 2 is semicircular and its outer surface is a curved surface, which is not perpendicular to the external force F applied to the side, the external force F can be decomposed, The external force F can be decomposed, and the external force F can be decomposed into two component forces F3 and F4 facing other directions and smaller than the external force, and the protruding structure 2 is curved, and a plurality of protruding structures 2 are located at the On the anti-crack line 40 , the actual length of the anti-crack line 40 is relatively long, which can effectively prevent the p...

Embodiment 3

[0051] see Figure 7 As shown, in the third embodiment of the present invention, the protruding structure 2 is triangular in shape, and the protruding structure 2 is disposed on the side of the barrier strip 1 away from the functional area 10 . Its force decomposition principle and Figure 4 The same, and will not be repeated here.

Abstract

The invention provides a display panel and a display device. The display panel comprises a functional area and a peripheral area surrounding the functional area. The functional area is provided with aperipheral working circuit, and the peripheral working circuit is adjacent to the peripheral area; the peripheral area comprises an anti-crack circuit surrounding the functional area; the anti-crackcircuit comprises a plurality of blocking strips arranged in parallel in the extending direction of the side edge of the functional area, and each blocking strip is provided with protruding structuresarranged at intervals. The display device comprises the display panel. According to the invention, the protruding structures are arranged on the anti-crack circuit and are used for gathering charges,and only the anti-crack circuit is damaged by explosion during an electrostatic test due to excessive charge accumulation, so that the resistance can be further improved, and the electrostatic protection capability of the anti-crack circuit is improved. Even if charges are accumulated, a working circuit in the panel is not influenced.

Description

technical field [0001] The present invention relates to the display field, in particular to a display panel and a display device. Background technique [0002] When designing a flexible display panel, in order to prevent external stress from entering the functional area and destroying the functional circuit, an anti-crack circuit (Ant i-Crack line) is usually added to the outermost periphery of the circuit; especially the glass cutting process in the current production process Next, when the display panel is cut, an external force will be generated around the panel. When the external force enters the panel, the anti-crack line will bear the stress first. When the external stress is too large, the anti-crack line will break, blocking the external force from entering the panel; avoiding internal functions Sexual lines are broken by external force. [0003] In order to avoid the risk of fracture caused by the above-mentioned external force, an anti-crack circuit structure is a...
