Infrared touch overlay is a kind of advance touch sensing device.It is installed on the surface of display equipment.It mainly consists of closely packed infrared transmitter and receiver tubes forming a matrix frame.When it working,the infrared transmitter tube continuously emits infrared light, and the receiver tube is responsible for receiving this light.When object touch screen,it will block part of the infrared light,so that the receiver tube cannot receive the light at the corresponding position.System can accurately determine the position of touch points to realize touch operation by detecting the position of the blocked light.
IR touch frame has many remarkable advantages.Fist of all,it has high sensitivity.It can quickly accurately respond to touch actions to bring fluency touch experience for users.Secondly,it has good stability.It doesn’t affect too much by environmental factors such as temperature and humidity, and can work reliably in a variety of complex environments.In addition,infrared touch panel is also high durability.It can withstand long time use and frequent touch operation without damage.Because of these advantages,infrared touch frame is widely used in all kinds of fields.On educational area,electronic whiteboards are often equipped with infrared touch frames to facilitate interactive teaching between teachers and students.On the business world, automatic service terminal adapt infrared touch frame to provide portable self-service for user.On the industrial control area,the display with infrared touch frame makes the operation more intuitive and efficient. In a world,infrared touch frame play an important role in modern technology.
