Problems solved by technology
[0003] There are certain drawbacks in the existing production methods of touch displays. Firstly, the structure of the touch screen is single-point operation, the performance of handwriting is poor, and the accuracy of virtual two-point gestures is also slightly poor, which is not easy to use. Secondly, the manufacturing process of Sensor is The screen printing process has low process yield and manufacturing efficiency. It is suitable for medium or large substrates, not suitable for small substrates, and has low stability. Finally, in the later lamination process, it is more convenient to bond without vacuum. The production effect of liquid glue lamination is not good, which reduces production efficiency. Therefore, we propose a production method for billboards

The invention relates to the field of displays, and discloses a production method of a touch display, and the production method comprises the following steps: S1, screen raw material blanking; s2, panel processing; s3, coating a film on the raw material; s4, a Sensor processing technology is carried out; s5, yellow light etching is carried out; s6, carrying out silk-screen printing and cutting; s7, fitting the rear end; and S8, assembling the display. The step S1 comprises the following specific steps: (1) placing corresponding raw materials in corresponding machines for processing; (2) the touch screen adopts a G + F + F structure: COVER LENSO (0.7) + 0CA (0.125) + film (0.125) + OCA (0.05) + film (0.125) = 1.125 mm; and (3) two layers of Film Sensors are used in the structure, and ITO is generally of a rhombus structure and supports real multi-point operation. The structure adopted by the touch screen is multi-point operation, the handwriting effect is good, a virtual third point or more can be achieved, maneuverability is good, the appearance of the Cover can be changed, the yellow light Sensor manufacturing process yield and manufacturing efficiency are high, the touch screen is suitable for being used basically with any size, stability is high, vacuum attachment is convenient, and production efficiency is improved.
Description
technical field [0001] The invention relates to the field of displays, in particular to a production method of a touch display. Background technique [0002] Touch screen display technology is a new type of human-computer interaction input method. Compared with traditional keyboard and mouse input methods, touch screen input is more intuitive. In order to meet the needs of market customers, a multi-point touch screen display has been developed. Handwriting input can also be realized. The touch screen is composed of a detection component installed in front of the display screen and a touch screen controller. When a finger or other object touches the touch screen installed in the front of the display, the touched position is detected by the touch screen controller, and is transmitted through an interface (such as RS-232 serial port) to the host. [0003] There are certain drawbacks in the existing production methods of touch displays. Firstly, the structure of the touch scre...
