Manufacturing process of multi-point touch single-layer film touch sensor

Abstract

The invention relates to a manufacturing process of a multi-point touch single-layer film touch sensor. The process is based on a three-dimensional (3D) printing process to perform layering printing on functional images of the sensor by starting from the bottom layer and overlaying the images layer by layer; after the functional images are formed, the functional images are glued to optical adhesive to be subjected to de-foaming, cutting and forming, and the manufacturing process of the multi-point touch single-layer film touch sensor can be achieved. The manufacturing process of the multi-point touch single-layer film touch sensor has the advantages that the process is single, configuration space of a factory is small, a single 3D printer device is merely required, personnel allocation is small, and producing costs are sharply reduced; the utilization ratio of raw materials is high, and consumables are used for solid printing of functional zone patterns by nearly 100%; proofing can be rapidly achieved, and the production cycle is shortened; the production line is quite short, deficient manufacturing procedure factors are few, and the product yield of the manufacturing process is higher than that of traditional processes; chemical solution treatment is absent, and producing costs are further lowered compared with those of the traditional processes; different dots per inch (dpi), each layer film thickness and the number of layers are set on a 3D printer to manufacture electrode patterns with different impedances.

Description

technical field [0001] The invention relates to a production process of a touch screen, more specifically, to a production process of a multi-touch single-layer thin-film touch sensor. Background technique [0002] Traditional touch screens are all produced by silk screen, acid etching or yellow light process. The process is complicated, the factory configuration space is large, the equipment requirements are large, the staffing is large, and the production and operation costs of the workshop are high. The traditional touch screen production process has low raw material utilization and high material cost; moreover, the production process has a long assembly line and a long production cycle, making rapid proofing impossible. [0003] The long production process line will easily lead to many bad factors in the process and relatively low product yield; the production process requires special chemical solution treatment, which is likely to cause pollution to the workshop and fur...

Problems solved by technology

[0002] Traditional touch screens are made by silk screen, acid etching or yellow light process. The process is complicated, the factory configuration space is large, the equipment requirements are large, the staffing is large, and the production and operation costs of the workshop are high.

The traditional touch screen production process has low raw material utilization and high material cost; moreover, the production process line is long and the production cycle is long, so it is impossible to achieve rapid proofing

[0003] The production process line is long, it is easy to cause many bad factors in the process, and the product yield is relatively low; the production process requires special chemical solution treatment, which is likely to cause pollution to the workshop and further increase production costs

[0004] The impedance of the electrode pattern produced by the traditional touch screen production process can only be single, and the function of the finished product can only be optimized by software, and the yield rate of the complex electrode pattern cannot be guaranteed. Furthermore, it is difficult to achieve a single-layer thin structure with Multi-touch capacitive screen
