specific Embodiment approach

[0053] Further, see figure 1 As a specific implementation of the manufacturing process of the touch screen provided by the present invention, the step of disposing the entire insulating layer 2 on the ITO film 1 includes:

[0054] Print the entire surface insulating glue on the ITO film 1;

[0055] Bake the entire surface of insulating glue.

[0056] After printing the entire surface of the insulating glue on the ITO film 1, bake the entire surface of the insulating glue to obtain the entire surface of the insulating layer 2, which reduces the insulation pre-drying and exposure and development processes, and improves the production efficiency; the entire surface of the insulating layer 2 is printed and baked Set on the ITO film 1, it is easy to control the coverage area of ​​the entire insulating layer 2, and the pressure during printing is small, which is beneficial to protect the ITO film 1. The entire insulating layer 2 formed by the printing process has strong adhesion to the ITO...

Abstract

The invention discloses a manufacturing process for touch screens. The manufacturing process comprises following steps: a plurality of X electrodes and a plurality of Y electrodes are etched on an ITOfilm, a whole surface insulating layer is disposed on the ITO film, and a silver paste layer is disposed on the ITO film; the X electrodes and the Y electrodes are insulated from each other, the X electrodes are kept continuous in the X-axis direction, and the Y electrodes are disconnected in the region crossed with the X electrodes; openings for exposing the Y electrodes are provided on both sides of the entire insulating layer corresponding to the disconnection region of each Y electrode; the silver paste layer comprises multiple bridging wires and multiple edge lines, wherein the bridgingwires are corresponding to the disconnection regions of Y electrodes one for one; the bridging wires are located on the entire insulating layer and extend into the opening and turn on the Y electrodeson both sides of the corresponding disconnected regions. Bridging wires for connecting the Y electrodes on both sides of the disconnected regions and edge lines for connecting the X electrodes or theY electrodes to the IC controller are synchronously fabricated, which simplifies process; there is no need to separately make bridging insulation and bridging silver paste, which greatly increases production efficiency.

Description

Technical field [0001] The invention belongs to the field of touch screens, and specifically relates to a manufacturing process of a touch screen. Background technique [0002] The capacitive touch screen works by using the induced current of the human body. When a finger touches a certain point on the screen, the touch IC controller of the touch screen needs to obtain the current information of the point in the X-axis direction and the Y-direction respectively for accurate calculation The location of the touch point. Commonly used capacitive touch screens generally use two-layer structure of ITO electrodes, which are used as X-axis electrodes and Y-axis electrodes respectively. The two layers of ITO electrodes are deposited on two substrates, and then the two substrates The materials are bonded with optical glue, and the upper substrate is bonded with the glass cover plate with optical glue, so that the ITO electrodes in the X-axis direction and the Y-axis direction work on the...
