When we are receiving customers, we are often asked, what is the difference between an industrial display and a regular display? How does it work? Next, let's take a look at the editor.
The industrial touch screen allows users to operate the host by simply touching the icons or texts on the computer display with their fingers. This eliminates keyboard and mouse operations and makes human-computer interaction more straightforward. It is mainly used in public hall information query, leadership office, electronic games, song and fruit, multimedia teaching, air ticket/train ticket pre-sale, etc. The products are mainly divided into three categories: capacitive touch screen, resistive touch screen, and surface acoustic wave touch screen.
The industrial touch display technology in industrial displays is a new type of human-computer interaction input method. Compared with traditional keyboard and mouse input methods, touch screen input is more intuitive. With the recognition software, the touch screen can also realize handwriting input. The touch screen is composed of a detection component and a touch screen controller installed in front of the display screen. When a finger or other object touches the touch screen installed in the front of the display, the touched position is detected by the touch screen controller and sent to the host through an interface (such as an RS-232 serial port). Large touch screen function, the multi-function smart board, computer and projector together form a large touch screen, the computer screen is projected onto the smart board through the projector, and the pointer or finger replaces the mouse to touch the computer on the smart board to control Windows or Macintosh and Its application software. Surface acoustic wave touch screen, the touch screen part of the surface acoustic wave touch screen is just a piece of transparent tempered glass, so it can be made into a flat, cylindrical or spherical surface, and there is no need to add a special coating on the surface of the touch screen. Ultrasonic transducers are installed on the corners of the touch screen, which can send a high-frequency sound wave across the surface of the screen.
When a finger or other object capable of absorbing or blocking sound wave energy touches the screen, the sound wave energy passing through the finger part is partially absorbed, and the coordinate position can be determined according to the change of the receiver signal. Compared with other types of touch screens in industrial displays, the sonic touch screen is not affected by environmental factors such as temperature and humidity, and has a resolution; good light transmittance, fast response, and third-axis response, so it is increasingly widely used.
