Multifunctional projection capacitor touch panel and manufacturing method thereof

Abstract

The invention relates to a manufacturing method of a multifunctional projection capacitor touch panel. The multifunctional projection capacitor touch panel comprises an outer cover touch substrate, a driving substrate and a sensing feedback substrate. The outer cover touch substrate on the uppermost layer is made of tempered glass, transparent materials are sprayed or etched on the upper surface of the outer cover touch substrate, roughness and touch are improved, and outdoor intense light is resistant. The driving substrate is a PET (polyethylene terephthalate) or PMMA (polymethyl methacrylate) flexible substrate or glass substrate. The sensing feedback substrate is a glass substrate. Both the driving substrate and the sensing feedback substrate are provided with transparent conductive circuits. After the transparent conductive circuits are led to the lateral side by a circuit made from conductive materials on lateral side of the integral transparent conductive circuits, the driving substrate and the controller are connected, and the circuits are protected by transparent insulation materials coated thereon. The three substrates are glued by optical adhesives. The manufacturing method of the touch panel have the advantages of manufacturability, especially for products larger than 15 inches, yield rate is high, material waste is reduced, the sensing layer feels smoother when touched with fingers, and external force impact resistance of the three substrates is improved remarkably.

Description

technical field [0001] The invention relates to the field of capacitive touch, in particular to a multifunctional projected capacitive touch panel and a manufacturing method thereof. Background technique [0002] Since the iPhone revolutionized the touch interface, humanized touch panel technology is gradually spreading from mobile phones to IT and consumer electronics fields such as handheld game consoles, all-in-one computers, and multimedia TVs. Touch panels will be one of the most important control interface development trends in the future. The touch screen proposed by the existing capacitive products adopts the DITO structure, and is made into a capacitive touch sensor board on the basis of forming column and row traces on both sides of the base layer. [0003] The existing technology is to form induction circuit layers on both sides of the same substrate, and the yield rate cannot be improved due to natural process problems in the production process, especially for l...

AI Technical Summary

Problems solved by technology

[0003] The existing technology is to form induction circuit layers on both sides of the same substrate, and the yield rate cannot be improved due to natural process problems in the production process, especially for large-sized products, more than 15 inches

High production cost and large material waste

[0004] Most of the existing touch panels, the human body contact sensing surface is glass, PET or PMMA, the touch feel will be obviously not smooth, especially for large-sized products

[0005] If the touch panel produced by the existing technology is applied to an all-in-one machine or a multimedia TV, the ability to resist external impact is relatively weak and it is easy to be damaged
