Everyone should know that the touch screen integrated machine is a human-computer interaction device widely used in office buildings and other places. It can quickly help people find the information they need by simply touching the screen. However, since the touch screen integrated machine uses three types of resistive touch screens, an infrared touch screen, and a surface acoustic wave touch screen, it is not known which type of touch screen is better.

1. Capacitive touch screen

The capacitive touch screen used in the touch screen integrated machine is mainly controlled by pressure sensing. It has high transparency, high strength, high light transmittance, small wire insulation points, good visual effects and so on. It recognizes any input signal, such as a finger (with or without gloves), a pen, a credit card, and more.

2. Infrared touch screen

The infrared touch screen used in the touch screen integrated machine is an infrared matrix in the X and Y directions in front of the screen. It can detect if there is infrared light blocked by the object and find the user's touch. This infrared touch screen is highly stable. Adaptability, light transmittance, not afraid of scratches, high durability, good use characteristics, no need to touch, no special requirements for the touch body, long service life and long touch life.

3. Surface acoustic wave touch screen

The surface acoustic wave touch screen is composed of a touch panel, a sound wave generator, a reflector, and a sound wave receiver. When the sound wave generator can transmit high frequency sound waves on the screen surface, when the finger touches the touch screen integrated machine screen, the sound waves on the contacts are blocked, thereby determining the coordinate position. The surface acoustic wave touch screen has a very high resolution. It has a long service life and is scratch resistant. It is not affected by environmental factors such as temperature and humidity and is suitable for use in public places.
