With the development of science and technology, more and more fields are applied to capacitive touch screen, which is also deeply loved by many users.
What is a capacitive touch screen
The technology of capacitive touch screen works by using the current sense of human body, and it is made of multi-layer glass screen. When your finger touches the metal layer, due to the electric field of the human body, the user forms a coupling capacitance with the touch screen. For high-frequency current, the capacitance is a direct conductor, so the finger absorbs a small current. This current flows from the electrodes on the four corners of the touch screen, and the current of these four electrodes is proportional to the distance between your finger and the four corners. The location of the touch point.
What are the benefits of applying China capacitive touch screen
The touch screen has the advantages of fast response, easy communication, sturdiness, and space saving. It is currently the most convenient, simplest and most natural way of human-computer interaction. Users only need to gently touch the icons on the screen with their fingers. Or text can be operated, which brings great convenience to your life. No longer have to worry about whether the keyboard is good or not, and no need to search for a mouse everywhere.
Development of capacitive touch screen
The touch screen has experienced a development process from low-end to high-end, from infrared touch screen, four-wire resistive touch screen to capacitive touch screen, and now it has developed to five-wire resistive touch screen and surface acoustic wave touch screen. The performance is more and more reliable, and the technology is more and more mature. With the different application characteristics of various industries, LCD is used in the fields of industry, medical treatment, tablet computer, bank terminal and other fields with the development of flat panel display technology.
After years of development, the function of the touch screen has developed from a simple inquiry and navigation to an all-in-one machine integrating business inquiry and Internet touch inquiry. The development of the IT industry is inseparable from the two basic elements of market capacity and price. Price cuts will generate some growth, but without a real market foundation, you can’t talk about product popularity, technology, and industry development.
Compared with other mature IT, the domestic touch screen market is still in its infancy, the huge business opportunities in the market have not yet fully emerged, and the technological development is not very perfect.
