1. contact or non-contact type infrared laser single-point or multi-point touch screen comprise that infrared laser radiated element on the circuit board and infrared ray receive the infrared laser receiving element on the sweep circuit plate, is characterized in that:

  • 1) at least one detection side on the contact panel to or a plurality of corner on the light that the infrared laser radiated element on infrared laser radiated element or the circuit board sends is installed, can on the position, outside the reception of infrared laser reception sweep circuit, can also be departed from the infrared laser that vertically promptly tilts relative by at least one and receive the sweep circuit reception vertical with it by at least one over against the position;

    2) the infrared laser radiated element is an iraser, launches a word light, and the infrared laser receiving element is infrared inductor or infrared camera;

    3) infrared laser radiated element and infrared laser receiving element are at same horizontal level, and all be placed on around the touch panel, the infrared ray of infrared ray one word laser instrument emission can be finished finger contact or non-contact type and touch apart from touch panel front or top less than 18mm;

    4) display device is a LCDs;

    5) the contact panel element is high contact panel transparent, that leaded light performance material high, insulation is made, attaches a kind of diaphragm that stops infrared ray, electrostatic prevention, anti-scratch that stops the infrared ray light the Infrared wave band that the infrared laser radiated element except that infrared laser radiated element or circuit board on launches on panel;

    6) controller component has input controller and o controller, and the input controller;

    the infrared laser receiving element is connected to hardware accelerator, is connected to processor device by accelerator again;

    O controller;

    infrared laser radiated element, LCDs are connected to processor device with interface;

    7) processor device is made of a high-performance computer, mainly carries out the contact and analyzes and calculate, and result of calculation is presented on the display device;

    8) software will receive contact information execution corresponding action and the order that sweep circuit transmits according to infrared laser.
