Self-adhesion flexible capacitive touch screen

Abstract

The invention discloses a self-adhesion flexible capacitive touch screen. The self-adhesion flexible capacitive touch screen comprises flexible tempered glass, a capacitive touch induction film and a transparent flexible film which are sequentially attached through a binding agent. Silica gel is attached to the bottom face of the transparent flexible film, a release film is attached to the bottom face of the silica gel, the capacitive touch induction film is provided with a transverse conducting circuit and a longitudinal conducting circuit, and outgoing lines of the transverse conducting circuit and the longitudinal conducting circuit are electrically connected with an IC controller. A finished product is attached to a display screen, the display screen is protected, and the display screen originally without the touch function can be touched through connection of a capacitive touch panel and a computer. The self-adhesion flexible capacitive touch screen is simple in structure, easy to assemble, convenient to fetch and replace and low in maintenance cost, any computer user can automatically install the self-adhesion flexible capacitive touch screen, and the self-adhesion flexible capacitive touch screen has wide market prospects.

Description

technical field [0001] The invention relates to the field of capacitive touch screens, in particular to a self-adhesive flexible capacitive touch screen. Background technique [0002] As a new type of human-computer interaction interface, the touch screen is widely used in various digital information systems due to its advantages of ease of use, durability, fast response, and space saving. With the development of technology, due to its thin thickness and high definition, the fully bonded integrated screen that combines the touch panel and the display screen can avoid the air layer between the display screen and the touch screen in the traditional frame sticking method. The display effect is poor, and the defect that the gap is easy to mold and fog has gradually become the mainstream of the market. However, since both the touch screen panel and the display screen have a certain degree of hardness, when the optical glue is used in the full lamination process, the screen will...

AI Technical Summary

Problems solved by technology

However, since both the touch screen panel and the display screen have a certain degree of hardness, when the optical glue is used in the full lamination process, the screen will have a dull phenomenon, and the larger the size, the longer the throwing distance, the more difficult it is to remove the air bubbles, resulting in The yield rate is low; at the same time, because the display screen is tightly bonded to the touch panel, once the touch panel on its surface is broken, the touch panel and display must be replaced at the same time during maintenance, resulting in the repair cost of the fully bonded screen Much higher than ordinary frame-mounted touch screens

[0003] In addition, at present, most office computers and home computer screens do not have touch functions. In order to meet users' needs for screen touch functions and solve the defects of existing fully-fitted integrated screens, it is urgent to develop a method that can eliminate frame-mounted touch screens. It also solves the problem that the touch display cannot be separated during maintenance, and at the same time, the user can install it independently, and it is tightly attached to the surface of the display screen to form a high-definition screen similar to a fully bonded screen. flexible capacitive touch screen
