Main features of Infrared touch screen

1, the stability of the height will not be caused by time, environment changes in drift.

2, the height of adaptability is not affected by current, voltage and electrostatic interference, suitable for some harsh environmental conditions.

3, high transmittance without intermediate medium, Infrared Touch Screen high transmittance, up to 100%.

4, long service life and durability, not afraid of scratching; The touch density can reach the 4096*4096 and the contact life is very long.

5, the use of a good touch no strength, no special requirements for the touch body, Infrared Touch Screen whether the touch is hard, or whether the touch is conductive, do not affect the normal use;
