Embodiment Construction

[0026] In order to solve the problem of large frame of the existing capacitive touch screen, a capacitive touch screen with small frame and a preparation method thereof are provided. Further elaboration will be given below through specific embodiments and accompanying drawings.

[0027] see figure 1 , a capacitive touch screen 100 according to one embodiment includes a driving layer 110 , a first adhesive layer 120 , a ground layer 130 , a second adhesive layer 140 , a sensing layer 150 , a third adhesive layer 160 and a panel glass 170 stacked in sequence.

[0028] The driving layer 110 is a driving electrode of the capacitive touch screen 100 . When the capacitive touch screen 100 is working, the drive layer 110 sends out low voltage and high frequency signals.

[0029] The driving layer 110 includes a transparent base film (not shown in the figure) and a conductive layer (not shown in the figure) laminated on the transparent base film. Considering both the conductivity a...

Abstract

The invention relates to a capacitive touch screen. The capacitive touch screen comprises panel glass, and the panel glass comprises a touching area and a wiring area placed on the edge of the touching area. The capacitive touch screen further comprises an induction layer, a ground layer, a driving layer, a first circuit and a second circuit, wherein the induction layer, the ground layer and the driving layer are sequentially laminated on the touching area, the first circuit is led out from the induction layer, the second circuit is led out from the driving layer, and the first circuit and the second circuit are arranged in the wiring area of the panel glass in an overlapping mode. By the aid of the ground layer, two capacitors are formed by the driving layer and the ground, and the induction layer and the ground respectively, variations of the two capacitors are both led out in a grounding mode, hence, the capacitors formed by the induction layer and the driving layer are prevented, and when the first circuit and the second circuit are arranged in the wiring area in the overlapping mode, the work of the capacitive touch screen can not be affected; due to the fact that the first circuit and the second circuit are arranged in the overlapping mode, wiring space is greatly reduced, the size of the wiring area is decreased, a frame of the capacitive touch screen is made to be small, and the application of the capacitive touch screen can cater to light and thin large-window design. The invention further provides a manufacturing method of the capacitive touch screen.

Description

technical field [0001] The invention relates to the technical field of touch screens, in particular to a capacitive touch screen and a preparation method thereof. Background technique [0002] At present, smart phones are becoming more and more popular, and the display screens of smart phones tend to be larger in size. The display screen of the mobile phone is larger, and the size of the mobile phone is required to be larger and larger accordingly. However, when the size of the mobile phone increases to a certain extent, the size of the mobile phone has a great impact on the portability and handling of the mobile phone. In order to alleviate the contradiction between the large screen of smart phones and the portability and controllability, mobile phone manufacturers and mobile phone touch screen manufacturers have proposed a new concept - capacitive touch screen narrow frame design. However, in the wiring area of ​​the narrow side design of the existing capacitive touch sc...
