I. Technology Research

The technological development of China's touch screen industry is ever-changing, and the main technology types include resistive, capacitive, infrared and surface acoustic wave. Among them, capacitive touch screen has become the mainstream technology in the current market due to its high sensitivity, fast response speed and durability. With the continuous progress of technology, new touch technologies such as OLED touch technology, flexible touch technology, ultrasonic touch technology, etc. are also gradually emerging.

Capacitive touch screen: It works by utilizing the principle of human body electrostatic induction and is widely used in consumer electronic products such as smart phones and tablet PCs. With the advancement of technology, the resolution, response speed, and durability of capacitive touch screens are constantly improving.

OLED touch technology: With the wide application of OLED screens in smartphones and tablet PCs, OLED touch technology has also developed rapidly. OLED screens have the advantages of self-illumination, vivid colors, high contrast, and bendability, which make the touch experience even better.

Flexible touch technology: The research and development of flexible touch technology has made breakthrough progress, and many Chinese enterprises have successfully mass produced flexible touch screens. Flexible touch screen not only has the characteristics of bendable and foldable, but also has higher durability and flexibility, which has a broad application prospect in the future in the field of wearable devices and smart phones.

Ultrasonic touch technology: Ultrasonic touch technology is favored by the market for its high precision and good user experience. The technology recognizes the touch position through the propagation change of ultrasonic waves on the screen surface, which is not affected by environmental factors such as temperature and humidity.
