Embodiment Construction

[0027] The invention discloses an OGS capacitive touch screen. see figure 1 , which includes: PET protective film 1 (also called high-temperature-resistant polyester film) stacked up and down, optical adhesive 2 (also called OCA), ITO functional sheet 3 (also called indium tin oxide), and pasted on ITO A flexible circuit board 4 (also known as FPC) on the upper or lower surface of the functional sheet. The ITO functional sheet displays images and receives external touch commands, and the flexible circuit board 4 connected to it transmits image data and touch commands, and the PET protective film attached to it plays a protective role in preventing scratches and bruises.

[0028] In a preferred embodiment, a circle of colored layers is screen-printed around the lower surface of the PET protective film. This layer can be a solid color block, such as a black frame, a red frame, a metallic color frame, etc., or it can be a variety of colorful patterns. In the past, the OGS colo...

Abstract

The invention discloses a one glass solution (OGS) capacitive touch screen which comprises a PET protective film, optical cement, an ITO functional piece and a soft circuit board, wherein the PET protective film, the optical cement and the ITO functional piece are arranged in an up-down overlapping mode, and the soft circuit board is attached to the upper surface or the lower surface of the ITO functional piece. The invention further discloses a manufacturing method of the OGS capacitive touch screen. The manufacturing method of the OGS capacitive touch screen includes the following steps: 1, preparing the PET protective film, and preparing the soft circuit board; 2, converting a functional pattern into a laser path; 3, leading the laser path into a laser device; 4, etching a large-piece ITO plate by using the laser device; 5, dividing the large-piece ITO plate and forming the single ITO functional piece in a splicing and combined mode; 6, connecting the soft circuit board to the ITO functional piece, and carrying out electrical logging on functions; 7, splicing the ITO functional piece and the PET protective film; 8, carrying out the electrical logging on finished products. The OGS capacitive touch screen and the manufacturing method of the OGS capacitive touch screen are rich in color, capable of preparing soft touch screens, simplified in production procedure, less in investment of production lines and environment-friendly in production, and products have higher competitiveness.

Description

technical field [0001] The invention relates to a touch screen, in particular to an OGS capacitive touch screen and a manufacturing method thereof. Background technique [0002] The mainstream production methods of SENSOR in the touch module industry are yellow light process and silk screen process. These two processes are heavily polluting production lines, which will discharge a large amount of waste liquid, and the maintenance cost of the production line is high, and the process flow is complicated. With the development of technology, the idea of ​​laser-made SENSOR appeared. The new process adopts a dry process, does not discharge waste liquid, occupies a small space, and adapts to flexible and diversified products. [0003] OGS (One Glass Solution), also known as TOL (Touch On LENS), is a new structure for the development of projected capacitive touch screens. Its biggest advantage is that it has the same function as the traditional Glass plus Glass structure, and is t...
