Embodiment Construction

[0020] Embodiments of the present invention will be described in detail below.

[0021] like Figure 1 to Figure 4 As shown, a capacitive touch screen includes an upper conductive film 1, a lower conductive film 2 and an optical adhesive layer 3, and the optical adhesive layer 3 is arranged between the upper conductive film 1 and the lower conductive film 2; the optical adhesive layer 3 includes an edge Part 4, forming a central void area 5 between the edge portions 4, the upper conductive film 1 and the lower conductive film 2 form a cavity 6 at the position of the central void area 5, and a plurality of insulating support platforms 7 are arranged in the cavity 6 .

[0022] Wherein, the edge portion 4 of the optical adhesive layer 3 is in the shape of a "mouth", the cavity 6 is a sealed structure, and the insulating support platform 7 is fixed to the lower conductive film 2 . The insulating support platforms 7 are uniformly distributed in the hollow area 5 in the middle.

Abstract

The invention discloses a capacitive touch screen which comprises an upper conductive film, a lower conductive film and an optical adhesive layer between the upper conductive film and the lower conductive film. The optical adhesive layer comprises edge portions, a middle hollowed-out area is formed among the edge portions, the upper conductive film and the lower conductive film form a cavity at the position of the middle hollowed-out area, and a plurality of insulating supports are arranged in the cavity. Quality and attractiveness of the touch screen can be effectively improved.

Description

technical field [0001] The invention belongs to the touch field, and in particular relates to a capacitive touch screen. Background technique [0002] The upper conductive film and the lower conductive film of the existing capacitive touch screen are bonded by an optical adhesive layer. Since the optical adhesive layer is solid, the two sides of the optical adhesive layer need to be connected to the upper conductive film, the lower conductive film, and the upper conductive film respectively during the bonding process. The lower conductive film is tightly bonded together, and a little carelessness will cause air bubbles in the touch screen, which are difficult to eliminate, affect the appearance of the touch screen, and cause poor function. Contents of the invention [0003] The object of the present invention is to overcome the defects of the prior art and provide a capacitive touch screen, which can effectively improve the quality and aesthetic effect of the touch screen....
