Abstract

The invention relates to an integrated capacitive sensing touch screen and a manufacturing method thereof, and relates to a capacitive touch screen. The integrated capacitive sensing touch screen is provided with a substrate, a transparent conductive film and a transparent conductive electrode are arranged on one surface of the substrate, a color coating layer is arranged in a non-visible range of the touch screen, and a space is reserved on the partial or complete transparent conductive electrode. A color ACP (anisotropic conductive paste) adhesive layer is arranged in the space and form the non-visible range of the touch screen together with a coverage range of the color coating layer. The transparent conductive film is deposited on the substrate. The transparent conductive layer and the transparent conductive electrode are manufactured by yellow-laser process. The color coating layer is manufactured in the non-visible range of the touch screen, and the space is reserved on the partial or complete transparent conductive electrode. The color ACP adhesive layer is manufactured in the space on the transparent conductive electrode and used for forming the non-visible range of the touch screen and a thermocured flexible circuit board to be connected with an external control circuit. Manufacturing procedures can be greatly reduced, production cost is reduced, and quality and yield of the integrated touch screen are improved.

Description

technical field [0001] The invention relates to a capacitive touch screen, in particular to a simple integrated capacitive sensing touch screen which can only use one yellow light process and a preparation method thereof. Background technique [0002] As a new type of human-computer interaction interface, the touch screen is widely used in various digital information systems, from small products such as mobile phones, digital products, to medium-sized products such as car navigators, tablet computers, game consoles, and household appliances. Touch screen products can be seen on large-scale products such as public inquiry systems, portable computers, and medical instruments, and the market prospect is very promising. The present invention specifically refers to a simple integrated capacitive sensing touch screen applied to smart phones, tablet computers, game consoles, portable computers and the like. [0003] An existing traditional integrated capacitive sensing touch scree...
