Description:
USB Touch Screen for 28" LCD 1.Supports Windows XP/Windows7/Windows 8/Linux/Android 2.Fast response 3.Install easilyProductDescription:
Greatouch Infrared(IR) touch screen operate on the mechanism ofinfrared LEDs arranged in arrays on two adjacent bezel edges of thePCB with photo sensors placed on the two opposite edges functioningas transmitters and receivers. The LEDs emit infrared rayssimultaneously to form a grid of rays across the display. When theuser wishes to send a signal through touch, he/she can do so byinterrupting the light beams with a physical object. Since everyinfrared LED is independent, the touch screen is able to achievepositioning by analyzing the decrease in light at the correspondingphoto sensors. The signal is then processed by the controlcircuitry and sent to the PC for the coordinates of the touch eventto be displayed on screen or to be utilized by other software forrelevant signal operation.
IR Dual TouchScreen Main Feature:
1. Single-touch and Dual-touch
2. High stability without drift, free from the affects to timeand environment change
3. High suitability free from the interfere of currency,voltage, and static due to the complicated environment
4. High light transmittance reach as high as 100%, No filmoverlay, preserves optical clarity
5. Long service life, vandal- and abrasion-resistant, ScratchResistant, Water/Dust Resistant screens, ideal forrugged applications
6. Easy activation, no touch pressure is required; nospecial material is required for touch activation; any material,whether soft or hard, whether conductor or nonconductor can be usedas an activating stylus.
7. IP65 Waterproof, Full sealed design
Application:
1. Point-of-information kiosks
2. Electronic catalogs
3. Gaming, POS, ATM, lottery, and amusement
4. Industrial control rooms
5. Computer-based training
