Embodiment Construction

[0041] Refer to attached picture. The method for preparing a resistive touch screen provided by the present invention includes a preparation step of a conductive optical film and a preparation step of a conductive glass;

[0042] The preparation steps of the conductive optical film include:

[0043] 1. see figure 2 Part (1) of the raw material conductive optical film 301 is partially etched to obtain the required conductive touch operation area 302; the etching methods include laser etching and acid etching. From figure 2 It can be seen in part (1) that the raw conductive optical film 301 accommodates four electro-optical film units adapted to the touch screen (according to the actual situation, other numbers can be selected for the typesetting capacity). The following steps are described in terms of The electro-optic film with a touch screen unit and the preparation process of the conductive glass are described.

[0044] 2. see figure 2 In parts (2) and (3), the first...

Abstract

The invention provides a method for manufacturing a resistance-type touch screen. The method comprises the following steps of: preparing a conductive optical film; and preparing conductive glass. The invention also provides the resistance-type touch screen which is manufactured by using the method. The resistance-type touch screen consists of the conductive optical film and the conductive glass, wherein the conductive optical film and the conductive glass are bonded by using a double-sided adhesive tape. By adoption of the method provided by the invention, production flow is simplified, yield is improved, and labor time is saved, so that the aim of reducing production cost is fulfilled. The resistance-type touch screen has a two-layer structure and a decoration effect, the conductive optical film serves as an upper electrode, and the conductive glass serves as a lower electrode and a supporting plate. By adoption of the method provided by the invention, the conductive optical film has a conductivity function and the appearance of a decoration part, and can be colorful according to an appearance requirement, so that the conventional decoration parts which are required to be individually arranged are eliminated.

Description

technical field [0001] The invention relates to a method for manufacturing a resistive touch screen and the resistive touch screen. Background technique [0002] With the popularization of computer technology, in the early 1990s, a new type of human-computer interaction technology --- touch screen appeared. The touch screen technology applied on the mobile communication platform is mainly resistive and capacitive. Resistive touch positioning is achieved by using the principle of resistive voltage division, with precise positioning, sensitive response, light weight, low power consumption, and low price. It is currently widely used in low-end and middle-end markets. At present, the widely used resistive touch screen has the following structures: [0003] 1. The ITO film is used as the upper electrode, and the ITO glass is used as the lower electrode and the support plate at the same time. The upper and lower electrodes are bonded with double-sided tape, and the signal is dra...
