[background technology]
Optical touch screen is take advanced person's optical technology as relying on, adding reflectorized material, and can accomplish that the 15--250 inch does not wait, in theory, LED sends infrared ray and is parallel to glass, by parallel the returning in parallel, the former road of reflectorized material, is received by CCD SENSOR.But in the practical application, there is the device of the frangible heavinesses such as glass, structural member in this technology, has brought great inconvenience for transportation and client's installation, even causes deformation so that touch-screen normally to use.In addition, different liquid crystal display producer same size has but been developed the liquid crystal display of different size, and customization brings sizable trouble to touch-screen.
[summary of the invention]
The utility model provides a kind of optical touch screen and optical touch screen systems, can make the application of optical touch screen not be subjected to size restrictions, not interfered by space structure.
Optical touch screen of the present utility model comprises at least two camera modules, and described camera module comprises process chip and camera, adopts stretchable connecting line to connect between each described camera module; Described camera is used for gathering image data, and described process chip is used for generating touch data information.
As an embodiment, the quantity of described camera module is two, be respectively main camera module and secondary camera module, described secondary camera module is transferred to described main camera module with the touch data information serial that generates, the touch data Information generation coordinate information that described main camera module generates the touch data information that self generates and described secondary camera module.
As an embodiment, the quantity of described camera module is three, be distributed in three corners of described optical touch screen, comprise a main camera module and two secondary camera modules, the touch data information serial that described secondary camera module is used for generating is transferred to described main camera module, and described main camera module is for the touch data Information generation coordinate information of the touch data information that will self generate and described secondary camera module generation.
As an embodiment, four of the quantity of described camera module, be distributed in four corners of described optical touch screen, described camera module comprises main camera module and three secondary camera modules, described secondary camera module is transferred to described main camera module with the touch data information serial that generates, the touch data Information generation coordinate information that described main camera module generates the touch data information that self generates and described secondary camera module.
Optical touch screen systems provided by the invention comprises optical touch screen and computing machine, adopts stretchable connecting line to be connected between described optical touch screen and the described computing machine;
Described optical touch screen comprises camera module, and described camera module comprises process chip and camera, adopts stretchable connecting line to connect between described each camera module; Described camera is used for gathering image data, and described process chip is used for generating touch data information; Described camera module comprises main camera module and secondary camera module, and the process chip of described main camera module is used for described touch data Information generation coordinate information is sent to described computing machine.
Adopt stretchable connecting line to connect between each camera module of the present utility model, distance between each device can be controlled by connecting line, the user can design the length of connecting line as required, and glass and structural member part can be by user's designed, designeds, therefore overcome glass and structural member transportation hard problem, so that the structure of optical touch screen is not subjected to the restriction of screen size, structure applications is more flexible, owing to removed outside structural member part, touch-screen product design trend is thinner simultaneously.
In the prior art when touching near camera zone, because whole camera can be blocked, so that can't position, judicious touch point, when use only has the touch-screen of two cameras, must avoid sheltering from the sensitizing range of whole camera lens during design, therefore camera needs wider space, and the utility model can be selected the camera of various quantity as required, after four cameras have been arranged, when touching near the camera regional location, can rely on away from two other camera of touch location and locate.Use four camera sides not have this sensitizing range problem, can do to get the narrower space, camera sensitizing range that do not take, camera only needs narrower space.
