Abstract
The invention relates to the technical field of display devices, in particular to an optical touch screen module. The optical touch screen module comprises a display region and a control board, wherein at least three cameras are arranged on the periphery of the display region, and the periphery of the display region is further provided with an emitting edge or a reflecting edge; the cameras are in electric connection with the control board, the three or more than three cameras can capture touch operation of multiple objects simultaneously, and therefore a multi-person and multi-point touch effect can be really achieved. When people use two or more than two light impermeable objects to write at the same time, lines are smooth, the problems that 'the lines break and the lines jump out' are fundamentally solved, a 'true optical multi-point touch' effect is achieved in a true sense, fingers, gloves, pens and other touch objects can be supported, a single person writing method and a multi-person simultaneous writing method can be supported, and therefore the optical touch screen module is convenient to use, simple in structure and suitable for being used in the display devices, teaching devices, meeting systems and the like.
Description
technical field:
Patent of the present invention relates to display device technical field, relates in particular to a kind of optical touch screen module.
background technology:
Traditional optical touch screen is comprised of two cameras, control panel, light-emitting section/reflecting strips etc.Traditional optical touch screen only can be realized multiple point touching by modeling algorithm, can inevitably produce the phenomenon of multiple spot " erroneous judgement " simultaneously, consequently, when people write with two or more lighttight object simultaneously, lines performance is not smooth, easily occurs the problem of " broken string, wire jumper ".
patent of invention content:
The object of patent of the present invention is exactly to provide for the deficiency of prior art existence the optical touch screen module that at least three cameras of a kind of employing catch, lines performance is smooth, can really realize multiple point touching operation.
To achieve these goals, the technical scheme that patent of the present invention adopts is:
Optical touch screen module, it includes viewing area, control panel, and the periphery of viewing area is provided with at least three cameras, and the periphery of viewing area is also provided with transmitting side or reflection limit, and camera is electrically connected to control panel.
Described reflection limit is infrared reflecting bar.
Described transmitting side is the inner infraluminescence bar that is provided with infraluminescence LED lamp.
Other three limits that described camera is all arranged on the Shang， viewing area, a limit of viewing area arrange respectively a reflection limit.
Described viewing area, along being laterally divided into a plurality of viewing areas, is provided with control panel and at least two cameras that are electrically connected to control panel in each viewing area, the control panel between viewing area is electrically connected to mutually.
Described viewing area can be also that four angles are respectively provided with a camera.
Described control panel is connected with for coordinate signal being transferred to USB interface or the wireless transport module on computing machine.
Patent beneficial effect of the present invention is: patent of the present invention includes viewing area, control panel, the periphery of viewing area is provided with at least three cameras, the periphery of viewing area is also provided with transmitting side or reflection limit, camera is electrically connected to control panel, more than three or three cameras can catch the touch operation of a plurality of objects simultaneously, can realize real many people, the touch effect of multiple spot, when people write with two or more lighttight object simultaneously, lines performance is smooth, fundamentally solved " broken string, wire jumper " problem, realized " touch of optics true multi-point " of real meaning, support finger, gloves and pen etc. touch object, support single gesture and many people to write simultaneously, easy to use, simple in structure, be applicable to display device, teaching equipment and conference system etc.
accompanying drawing explanation:
Fig. 1 is the structural representation of patent of the present invention.
Fig. 2 is the distribution schematic diagram of patent the second embodiment camera of the present invention.
Fig. 3 is the distribution schematic diagram of patent of the present invention the 3rd embodiment camera.
embodiment:
Below in conjunction with accompanying drawing, patent of the present invention is further described, as shown in Figure 1, optical touch screen module, it includes viewing area 1, control panel 2, and viewing area 1 is rectangular configuration, and its periphery has four edges, the periphery of viewing area 1 is provided with four cameras 4, the periphery of viewing area is also provided with transmitting side or reflection limit 3, and camera 4 is electrically connected to control panel 2, and viewing area 1 can be electronic whiteboard.Other three limits that four cameras 4 are evenly arranged on the Shang， viewing area, a limit 1 of viewing area 1 arrange respectively a transmitting side or reflection limit 3.
Reflection limit can be infrared reflecting bar, and transmitting side is the inner infraluminescence bar that is provided with infraluminescence LED lamp, when the Infrared of needs is more intense, just by transmitting side, when infrared light without too strong just with reflection limit.When the length dimension of viewing area 1 is less than 2 meters, can adopt reflection limit or transmitting side, when three reflection limits are infrared reflecting bar, can reduce costs widely; When the size of viewing area 1 is more than or equal to 2 meters, adopt transmitting side, three transmitting side are the inner infraluminescence bar that is provided with infraluminescence LED lamp, have strengthened the intensity of infrared signal, make to touch better effects if.
When the length dimension of viewing area 1 is less than 2 meters, full frame support two people write simultaneously; When the size of viewing area 1 is more than or equal to 2 meters, viewing area 1 is along being laterally divided into two viewing areas, in each viewing area, be provided with control panel 2 and at least two cameras 4 that are electrically connected to control panel 2, control panel 2 between viewing area is electrically connected to mutually, and each viewing area supports that two people write simultaneously.
Patent of the present invention adopts three or three above cameras 4, can catch the touch operation of two above objects simultaneously, can realize the touch effect of real many people, multiple spot, when people write with two or more lighttight object simultaneously, lines performance is smooth, fundamentally solved the problem of " broken string, wire jumper ", realized " touch of optics true multi-point " of real meaning, support finger, gloves and pen etc. to touch object, support single gesture and many people to write simultaneously, easy to use, simple in structure.
As shown in Figure 2, as the second embodiment of patent of the present invention, different from a upper embodiment, camera 4 is three, and three cameras 4 are evenly arranged on a limit of viewing area 1.
As shown in Figure 3, as the 3rd embodiment of patent of the present invention, different from a upper embodiment, camera 4 is four, and four angles of viewing area 1 are respectively provided with a camera 4.
Certainly, the above is only the preferred embodiment of patent of the present invention, and the equivalence of doing according to structure, feature and principle described in patent patent claim of the present invention therefore all changes or modifies, and is included in patent patent claim of the present invention.
