Touch Screen

Technology includes Surface Acoustic Wave (SAW), Resistive (4-wire,5-wire,8-wire), Capacitive etc. USB or RS232 interface for your optional. Compliance with CE, FCC, ROHS etc. From 5" to 42" available for CRT or LCD TFT monitors.




SAW Touchscreen

Surface acoustic Wave (SAW) technology provides better image clarity because it uses pure glass construction. A SAW touchscreen uses a glass display overlay and is suitable for screen sizes from 6.4" up to 42". When sound waves are transmitted across the surface of the display, each wave is spread across the screen by bouncing off reflector arrays along the edges of the overlay. Two receivers detect the waves. When the user touches the glass surface, the user¡¯s finger absorbs some of the energy of the acoustic wave and the controller circuitry measures the touch location. SAW Touchscreen technology is used in ATMs, Amusement, Gaming, Banking and Financial Applications and kiosks,POS etc. The technology is not able to be gasket sealed, and hence is not suitable to many industrial or commercial applications. Compared to resistive and capacitive technologies, it provides superior image clarity, resolution, and higher light transmission.

4 Wire Touchscreen

4 wire resistive touchscreen is an outstanding high quality product, suitable for low cost solution and superior value. It is inherently of many advantages containing exact and fast response, touch by any object, liquid resistance and contamination against. This kind of touchscreen should be used for extensive applications as POS systems, KIOSK, MEDICAL, IPC, GAMING, PDA and related equipment.

5 Wire Touchscreen

5 wire resistive touchscreen features unrivaled accuracy, reliability, superior light transmission, highest touchpoint density, touch input variety. Impervious to environmental conditions such as liquid splashes, contamination. The lifetime is up to 35 million finger touches, much better than 4 wire resistive touchscreen. This kind of touchscreen should be used for extensive applications as POS systems, KIOSK, MEDICAL, IPC, GAMING, PDA and related equipment.

Capacitive touchscreen

A capacitive touch screen consists of a glass panel with a capacitive (charge storing) material coating its surface. Circuits located at corners of the screen measure the capacitance of a person touching the overlay. Frequency changes are measured to determine the X and Y coordinates of the touch event. Capacitive type touch screens are very durable, and have a high clarity. They are used in a wide range of applications, from restaurant and POS use to industrial controls and information kiosks.
