The development of touch screens shows the trend of professionalization, multimedia, three-dimensional and large-screen. With the development of the information society, people need to obtain a variety of public information. The public information transmission system with touch screen technology as the interactive window adopts advanced computer technology and uses text, image, music, commentary, animation, video and other forms to intuitively and vividly introduce various information to people and bring them to life. It's a great convenience.
Touch screen technology has brought tremendous changes to the consumer electronics field. The interface of the device has become more user-friendly and easy to use. Only the light touch of a finger can transform a physical touch into a digital code. The new man-machine interface introduces new product concepts and innovates the structural design of 3C products. Under the concept of modular design, system integration creativity allows system designers to activate product system design creativity. The introduction of new technologies has driven the reorganization and transposition of the entire upstream and downstream industrial chain.
It is foreseeable that with the rapid development of touch screen technology, touch screens will play an important role in the popularization and utilization of computer technology. The application fields of touch screens will become wider and wider, and their performance will become better and better. Understanding the development trend of touch screen technology is very necessary for the correct development of touch screen products. The development trend of touch screen technology is:
1) Resistive touch screen is still the mainstream in the market. Although the service life of resistive touch screens is not very long and the transmittance is not good, it is the most commonly used touch screen technology on the market. Its low price and good response to fingers and touch pens make it the most sold touch screen product in the past 5 years.
In terms of current market development, resistive touch screens have price advantages. Among them, Samsung and LG’s new full-screen touch phones almost all use resistive touch screens. However, this situation may change in the next few years. Projected capacitive and infrared touch screens have also begun to penetrate the wireless handheld device market in 2007.
2) The price gap between capacitive and resistive touch screens is narrowing. Although capacitive touch screen technology has been promoted due to the launch of the iPhone, its application is not limited to touch screens for small-sized handheld devices, but also in PC-related fields such as mice and keyboards, and even home appliances , Kiosk, and various applications related to life make capacitive touch more in line with the needs of future electronic products. Due to the wider application range, capacitive touch screen technology is widely favored. It is believed that capacitive touch will replace resistive touch and become the mainstream of small-size panel applications.
