Flexible touch screen, manufacturing method thereof and flexible display device

Abstract

The invention provides a flexible touch screen, a manufacturing method thereof and a flexible display device. The flexible touch screen comprises a substrate, first electrodes, second electrodes, an insulating layer and a bridging conducting layer, wherein the first electrodes and the second electrodes are arranged on the substrate, the first electrodes are arranged continuously, the second electrodes are divided into a first part and a second part at the intervals of the first electrodes, and the first part and the second part do not make contact with each other; the insulating layer is arranged on the second electrodes, the first part and the second part; and the bridging conducting layer is arranged on the insulating layer and electrically connected with the first part and the second part, wherein the included angle between the projection of the bridging conducting layer on the insulating layer and the edge, making contact with the bridging conducting layer, of the insulating layeris not 90 degrees. Through the flexible touch screen and the manufacturing method thereof, by the adoption of arc design of the bridging conducting layer, the joint between the bridging conducting layer and the insulating layer is not prone to fracture, and bending resistance of a product is improved.

Description

technical field [0001] The invention relates to the technical field of touch screens, in particular to a flexible touch screen, a manufacturing method thereof, and a flexible display device. Background technique [0002] Flexible touch screens have been widely used at present. The contact condition of the electrodes in a flexible touch screen plays an important role in the touch performance. A bridging structure of a touch screen is disclosed in the prior art, which includes a substrate on which a coated conductive layer and a plurality of bridge point areas are arranged. The bridge point area is covered with a bridge point insulation protection layer, and at least two linear metal bridges arranged in parallel are arranged above the bridge point area. [0003] Another technology also discloses a flexible touch screen, including a transparent flexible substrate, a transparent conductive film layer arranged on the transparent flexible substrate, and the transparent conductiv...

[0003] Another technology also discloses a flexible touch screen, including a transparent flexible substrate, a transparent conductive film layer arranged on the transparent flexible substrate, and the transparent conductive film is a plurality of first electrodes 102 and a plurality of second electrodes etched by laser 101 (the first electrode and the second electrode refer to the driving electrode and the sensing electrode); wherein the first electrode and the second electrode cross each other to form a touch sensing pattern, the first electrode 102 is continuously arranged, and the second electrode 101 is arranged in the first The electrodes are touch units separated by intervals so as not to communicate with each other; a transparent insulating polymer film layer 103 formed by printing is provided on the second electrode at the division, and a bridging conductive part is provided on the transparent insulating polymer film layer 104, conduct the second electrode 101 to form a bridge structure such as figure 1 , but the bridging structure is very easy to break at position 106, which is not suitable for mass production in flexible products, and the risk of mass production is extremely high

[0004] At present, there is an urgent need to solve the problem that the intersection of the metal bridge and the insulating edge is easy to break during the bending process of the touch screen
