Description

The present invention relates to a touch control unit, and more particularly, to a touch control unit having an effect of greatly reducing the thickness and reducing the production cost.

Among them, the capacitive touch control panel structure is widely adopted because it has characteristics such as dustproof, fireproof and high analytical degree. The principle of the touch-sensitive touch panel is mainly to detect the position of the contact point based on the change in capacitance and use the electrical change in capacitance generated between the electrodes due to the proximity of the touching object (conductor such as fingers) Then, the coordinates of the first extending end and the second extending end contact point are determined.

Detect the change of finger position and click selection situation to achieve the purpose of operation control.

A general capacitive multi-point touch control panel is applied to a two-layer touch control panel, and the two-layer touch control panel performs a multi-channel screen printing process or a photo-etching process on each transparent conductive substrate. The transparent conductive substrate is made of glass, the transparent conductive substrate is expensive, and a relatively large amount of production material is consumed at the time of manufacture. If a defective product is generated in the touch control panel process, the entire touch control panel needs to be disposed of and cannot be recycled, resulting in a waste of cost. Must have a tin (ITO) layer, perform its multi-channel screen printing process or photo-etching process, and The manufacturing process is complicated and the manufacturing cost is significantly increased, and the two-layer touch control panel increases the overall thickness of the electronic device, satisfying the light and thin requirements of portable electronic devices Thus, disadvantages such as a relatively large overall thickness need improvement. Therefore, the prior art has the following disadvantages:
1.
Thicker;
2.
The manufacturing process is complex;
3.
Manufacturing cost is relatively high.

  Therefore, how to solve the above-mentioned conventional problems and defects is where the inventor of the present application and related companies engaged in the industry want a direction of research improvement.
