Flexible substrate, state detecting method thereof and display device

Abstract

The embodiment of the invention provides a flexible substrate, a state detecting method thereof and a display device and relates to the field of display technology. The state detecting method of the flexible substrate can timely and effectively detect the state of the flexible substrate. The flexible substrate comprises a base substrate, a driving chip arranged on the base substrate, at least onedetecting terminal group arranged on the base substrate, and metal wires connecting the target signal receiving ends and the detecting signal output ends of the detecting terminal groups, wherein theedge of the driving chip is composed of first edges and second edges which are perpendicular to each other, and the length of the first edges is smaller than that of the second edges; every detectingterminal group is composed of one target signal receiving end and one detecting signal output end; the metal wires in partial areas extend along the third edges of the base substrate within a preset distance range, and the third edges are adjacent to one of the first edges, and in the extending direction of the second edges, one of the third edges, one of the first edge, the other first edge and the other third edge are sequentially arranged.

Description

【Technical field】 [0001] The invention relates to the field of display technology, in particular to a flexible substrate, a state detection method thereof, and a display device. 【Background technique】 [0002] In order to reduce the frame width of the display panel, the driver chip on the display panel is usually arranged on a flexible substrate, and then the flexible substrate provided with the driver chip is bound to the display panel and bent towards the back side of the display panel to The narrow frame design of the display device is realized. [0003] In the production process of flexible substrates, such as figure 1 As shown, the flexible substrate 10 is shipped in the form of a coil, which is cut into individual flexible substrates through a cutting process, and then bound into the display panel. However, during the cutting process, the edge of the flexible substrate may be slightly torn, or the edge may be cut off due to low cutting precision. For example, when c...

AI Technical Summary

Problems solved by technology

[0004] When the edge of the flexible substrate is slightly torn, after it is bound to the display panel, the tearing degree of the edge will become larger and larger, which will affect the installation stability of the flexible substrate, and then affect the normal display of the display panel

When the edge of the flexible substrate is cut off, it will cause the pins in the binding area to be cut, and after it is bound to the display panel, it will also affect the normal display of the display panel

Moreover, when the edge of the flexible substrate is abnormal due to the cutting process, if it is not detected in time, it will lead to subsequent cutting of many problematic flexible substrates, resulting in waste of materials
