Description
Technical field
The utility model relates to a kind of touch-screen, relates in particular to a kind of infrared touch screen.
Background technology
Large-screen display equipment is used more and more widely, and forward multifunctional direction development, particularly interaction function; And install touch-screen additional is modal mode, and infrared touch panel does not receive electric current, voltage and electrostatic interference, have cheap, easy for installation, need not block or the advantage of other any controller; Simultaneous adaptation property is strong; Good stability, response speed is fast, therefore uses the most extensive.Traditional method that installs additional is that infrared facility is installed on the shell of display device, but this mounting means poor reliability is not attractive in appearance.
The utility model content
The utility model provides a kind of infrared touch screen reliable, attractive in appearance for solving the prior art problem.
The technical scheme of the utility model is: a kind of infrared touch screen; Comprise screen and shell, it is characterized in that: the place ahead of screen is provided with protection screen, and shell is arranged at the edge of screen and protection screen; Be provided with circuit box between screen and the shell; Be provided with the infrared touch circuit in the said circuit box, the infrared touch circuit comprises circuit board, and the infrared touch pipe is installed on the circuit board.
The infrared touch screen device is installed in the shell of display device, shell protection infrared touch screen device, and infrared facility is installed more firmly under the prerequisite that does not change existing imaging device outward appearance, receives ectocine little, and dependability is high; Screen arranged outside protection screen makes screen when touching, be protected, and can not be scratched longer service life.
As preferably, said circuit box xsect is L-shaped, and the external port of circuit box has window, and the window place is equipped with light-passing board.
As preferably, the control device of infrared touch pipe is installed also on the said circuit board.
As preferably, said infrared touch pipe comprises infrared transmitting tube and infrared receiving tube; The window that is positioned at the circuit box of the relative both sides of screen is oppositely arranged, and said infrared transmitting tube and infrared receiving tube are in the same plane.
In sum, the utlity model has following advantage:
1, the infrared facility installation is more stable, and reliability is high, receives ectocine little;
2, pattern is attractive in appearance.
