Embodiment Construction

[0036] Such as Figure 1 to Figure 6 Shown, in the present invention, select the glass substrate 1 that has plated ITO for selection, process the ITO electrode 2 earlier by etching process in the first process, as figure 1 shown. Then print the frame layer 4 again. Set up a visible area in the middle of the frame layer 4, and evenly arrange through holes 3 around the visible area, because the metal traces of the ITO electrode 2 and the circuit layer 5 are respectively located on both sides of the frame layer 4, which cannot be solved by general design. There is a conduction problem between these two layers, so through holes 3 are set on the frame layer 4, such as figure 2 shown. The wiring material of the capacitive screen on the circuit layer 5 is generally made of silver paste, which is off-white in color and cannot be directly printed on the through hole 3 of the frame layer 4 . In order to solve this problem, a conductive layer 6 is printed on the through hole 3. In t...

Abstract

The invention provides an OGS capacitive touch screen and a production method thereof. An ITO electrode is arranged on the substrate, a border layer is arranged on the ITO electrode, a circuit layer is arranged on the border layer, and a cover plate layer is arranged on the circuit layer; a metallic circuit is distributed on the circuit layer; the border layer comprises a conducting layer, a border and at least two through holes, the through holes are formed in superposed positions of the ITO electrode and the metallic circuit of the circuit layer, and the conducting layer is arranged in the through holes; the cover plate layer comprises a shading cover bottom and a cover plate through hole, and the cover plate through hole penetrates through the shading cover bottom and is arranged in a hot-press area. According to the OGS capacitive touch screen and the production method thereof, the requirements on equipment investment can be effectively lowered, so that the OGS capacitive touch screen can be extensively used.

Description

technical field [0001] The invention belongs to the field of touch screens, and in particular relates to an OGS capacitive touch screen and a manufacturing method thereof. Background technique [0002] Capacitive touch screen is a simple and convenient way of human-computer interaction. It has been widely used in various fields of our daily life, such as smartphones, smart watches, navigation systems, digital cameras, game equipment, monitors, electrical control, medical equipment and so on. Common touchscreen technologies include resistive and capacitive touchscreens for mobile devices and consumer electronics, and surface acoustic wave and infrared touchscreens for other applications. [0003] Because of its multi-touch and high-sensitivity performance, capacitive touch screens not only shine brightly in consumer electronics applications, but also become more and more popular in other fields. [0004] The external capacitive touch screen mainly has two structures, one is...
