touch screen usb display.The infrared touch screen is composed of infrared emitting and receiving sensing elements mounted on the outer frame of the touch screen. On the screen surface, an infrared detection network is formed. Any touching object can change the infrared on the contact point to achieve touch screen operation. The infrared touch screen is not affected by current, voltage and static electricity, which is suitable for some harsh environmental conditions. Its main advantage is that it is easy to install and does not require a card or any other controller. Any touch object can change the infrared on the contact to achieve touch screen operation. It can be used on computers of all grades. In addition, because there is no capacitor charging and discharging process, the response speed is faster than the capacitive type, but the resolution is lower , the maintenance is more troublesome, and the price is higher. It is suitable for various public places, offices and industrial control sites that do not require very precise interference without infrared and strong light interference. In addition, the infrared touch screen has a long service life, is highly durable, and is not afraid of scratching.
