Abstract
The invention discloses a monolithic substrate capacitive touch screen and a manufacturing method of the monolithic substrate capacitive touch screen. The method includes the steps that a large substrate is cut into a small substrate with the size needed by a product; the small substrate is physically and chemically reinforced; color insulation ink is printed on one side of the reinforced small substrate; a transparent conducting layer is plated on the side on which the insulation ink is printed of the small substrate; exposure developing etching is conducted on the side on which the transparent conducting layer is plated of the small substrate, and a needed touch circuit pattern is manufactured; a colloid adheres to the transparent conducting pattern, the small substrate and a lower layer display module are attached and assembled, and the conducting layer is protected. According to the method, the large substrate is cut into the small substrate needed by the product in advance, so that the problems that after a traditional touch screen pattern is manufactured, in the cutting process, a product is prone to breakage, edge strength is damaged severely, the product yield is reduced, and strength is not high are effectively solved. In addition, the touch pattern is formed only through one transparent conducting layer, so that the touch screen is simple in manufacturing process and low in cost.
