Abstract

The invention is applicable to the technical field of capacitive touch screens, and provides a method for manufacturing a flexible capacitive touch screen. The method comprises the following steps: cleaning of a flexible substrate: cleaning the flexible substrate with a cleaning machine; ink printing: printing a metal conductive ink on the surface of the flexible substrate with printing equipment, and forming a conductive circuit layer on the surface of the flexible substrate, wherein the conductive circuit layer comprises an X-direction induction module and a Y-direction induction module; curing treatment: baking the flexible substrate printed with the metal conductive ink. In the method, the printing equipment is used to print the metal conductive ink on the surface of the flexible substrate, so as to form the conductive circuit layer; the baking-curing treatment is performed to form the flexible capacitive touch screen; in the whole manufacturing process, only the cleaning machine, the printing equipment and baking equipment are used, so that the method greatly reduces equipment costs, has an electromagnetic shielding function, effectively reduces the signal interference, and can be used for producing circuits with high touch accuracy requirements and high density, such as the capacitive touch screen with narrow border and high touch accuracy.

Description

technical field [0001] The invention belongs to the technical field of capacitive touch screens, and in particular relates to a flexible capacitive touch screen and a manufacturing method of the flexible capacitive touch screen. Background technique [0002] The capacitive touch screen uses the current induction change of the human body to locate the touch position when touching. Touch technology of single-layer multi-point projected capacitive panel: single-layer multi-point projected capacitive touch screen is to etch ITO conductive circuit modules in different directions on a layer of ITO (indium tin oxide) conductive glass coating. The graphics etched on the two modules can be regarded as sliders that change continuously in the X and Y directions. Since the X and Y structures are on different surfaces, their intersections form a capacitor node. One slider can be used as a drive line, and the other slider can be used as a sense line. When the current passes through one...
