What is the IR touch screen?
Infrared (IR) Touch screen is a screen with which one interacts with the screen surface of the screen rather than using an input object such as a mouse, and works with IR light. With the IR touch screen there are many different diodes emitting IR lights (LED); When a finger or object changes the light pattern, the screen lifts the touch. Unlike some other touch screens that need a conductor such as a finger, the IR touch screen can be activated by almost any object. The IR screen screen may not be patterned, so these touch screens tend to have better durability and clarity compared to other touch screens. These touch screens are seen in cash registers, some computers and medical devices. When the user touches the screen, the touch disrupts the LEDs and the screen and the photodetector notice this disturbance. By correlation of two factors, this touch screen knows exactly where the user touched and simulated the mouse by clicking onthis area. This allows users to open files and click on the mouse -free buttons, which is much more useful in some applications.
Most touch screen hardware require a wire such as a finger or device, but the IR screen does not need it. The advantage is that anything can be used, so users do not have to buy or maintain special equipment. However, if something touches or unexpectedly touches the screen, it will register it as a touch. This means that the IR touch screen can be used finger, plastic or metal stylus, pen cap or anything else.
Many touch screen systems require glass with specialized patterns so that the computer can recognize where the user touches. The IR touch screen does not use this system, so the glass is the same as the conventional screen. The advantage of this is the glass usually takes longer and has better optical quality. At the same time, these screens can sometimes incorrectly behindRegister the touch because the touch interface is not so sophisticated.
IR touch hardware is most often seen in cash registers, some desktop computers and some medical devices. It is also used for some video games, but this is not very common. The reasons for the wide use of this touch screen are low maintenance and easy use.
