Optical touchscreen

Optical touchscreen technology uses multiple optical sensors to detect the touch point, which registers the touch just before physical contact with the screen. This means that users can apply zero or light touch to the screen to initiate a response, and any input device, such as a finger, gloved finger, pen, or stylus will work.

Just like Elo Touch Solutions' surface acoustic wave touchscreen technology, surface coating overlays are not used on the touch screen surface, which creates a crystal clear image. In addition, scratches on the touch surface will not affect the touch screen operation. This is important for high-use public environments such as lobbies, way-finding or kiosks.

• Greater than 90% transparency and true colour fidelity
• Stable, no-drift performance - no calibration required
• Recognises touch from virtually any object and scratches do not affect the touchscreen operation
