Abstract

The invention provides a flexible touch screen and a manufacturing method thereof. A touch induction electrode layer (2) and wires thereof and a touch drive electrode layer (4) and wires thereof are manufactured on the upper surface and the lower surface of a same flexible substrate (1) respectively, therefore, the technology complexity of the flexible touch screen can be reduced, the thickness of the flexible touch screen can be decreased, and the flexibility of the flexible touch screen is improved; the flexible substrate (1) is provided with via holes (7), the wires on the surface of one side are led to the other side, and then a flexible printed circuit (6) is welded to the surface of the same side; by improving patterns of the touch induction electrode layer (2) and additionally arranging shielding electrodes (22), vision disparity caused by the patterns of the touch induction electrode layer (2) is reduced, and the visual effect and the technology stability in the etching process are improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a flexible touch screen and a manufacturing method thereof. Background technique [0002] Existing liquid crystal displays, plasma displays, and organic electroluminescent displays mainly use glass substrates. Due to the shortcomings of glass substrates such as brittleness and easy damage, they are required to be portable, thinner, and lighter in the field of mobile display devices and large-size displays. Applications in the field of equipment are limited. Therefore, recently, flexible display devices prepared by using flexible substrates such as plastic substrates, metal foils, etc. instead of glass substrates have received widespread attention, and there will be broader development space in future display technologies. [0003] Touch screen (Touch Panel, TP), also known as touch screen, touch panel, as a human-computer interaction input device, is widely used in various elec...
