A new five-wire resistive touch-screen controller from eGalax provides advanced software designs, which are compliant with USB and RS232 interfaces and various hardware operating systems.

Five-wire touch screens are more complex and provide a certain redundancy factor not found in simpler four-wire systems.

According to eGalax, a five-wire touch screen is much more durable and will last much longer than a four-wire touch screen, and so is ideal heavy-usage applications including point-of-sale terminals, public information booths (kiosks), lottery drawing system, medical applications and industrial control equipments.

The eGalax five-wire touch-screen controller dramatically improves the screen performance in many ways.

The new product gives high resolution up to 2048 x 2048, provides support for serial RS232 and USB connection interfaces, enhances screen responses by four- or 25-point calibration, emulates right mouse button and double clicking functions, offers drawing test function support and device drivers which are fully compliant with operation systems like Windows 98, 2000, NT4, Me, XP, RedHat Linux, DOS and iMac, as well as the multi-language Windows utility.

"The goal of eGalax is to provide our customers by delivering innovative, world-class touch-screen controller products", said Mei Tsai, President of eGalax.

Besides the five-wire touch-screen controller, eGalax offers a full range of products that are ideal for a wide range of the most advanced touch screens, like the four-wire resistive touch-screen controller and capacitive touch-screen controller series.
