Touch screen working principle

Product characteristics

High precision of touch, you can draw the curve is very smooth and delicate;

Fast response speed, touching handwritten without delay; without a special surface coating, screen high-definition, scratches, dust;

To support more precise touch, point to any corner and touch screen;

Light weight, easy installation, the use of modular design, can be split;

A wide range of applications, suitable for various sizes of display device;

Provide built-in and external way, to meet different customer needs.

Using optical imaging touch technology, combined with Windows 7 perfect, implement the multi-touch and gesture recognition, can be naturally scaling, rotation and annotation, instinctively, so that more light, smooth touch, will touch the experience to a new height, fully demonstrated the unique charm of human-computer interaction the.
