Preferably, described circuit board is arranged on the outside of described touch panel.
Preferably, described electronic devices and components and described infrared receiving/transmission element are all between described circuit board and described touch panel.
Preferably, described electronic devices and components are between described circuit board and described shell.
Preferably, described frame also comprises the printing opacity frame, and described printing opacity frame is between described circuit board and described touch panel.
Preferably, described printing opacity frame has an a plurality of hole or the bit-avoiding slots kept away that are complementary with described infrared receiving/transmission element.
Preferably, described infrared receiving/transmission element comprises infrared receiver component and infrared emission component, and described frame also comprises convex lens, and described convex lens are positioned at the inboard on the limit that is provided with described infrared receiver component of described frame.
The infrared touch panel that utilizes the utility model to provide, because infrared emission component is sealed between circuit board and the touch panel, on the one hand because seal cavity has been avoided the loss of the Infrared that infrared emission component sends, on the other hand, touch panel is made by clear glass usually, infrared emission component is arranged between circuit board and the touch panel, can be returned infrared emission component by reflection of glass surface so that shine the light of glass surface in the Infrared that infrared emission component sends, thus so that the Infrared of sending reinforcement.
Description of drawings
Fig. 1 is the three-dimensional block diagram according to the structure of touch-screen of the present utility model.
Embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is a part of embodiment of the present utility model, rather than whole embodiment.Based on the embodiment in the utility model, the every other embodiment that those of ordinary skills obtain under the prerequisite of not making creative work belongs to the scope that the utility model is protected.
With reference to figure 1, the utility model provides a kind of infrared touch panel, this infrared touch panel comprises frame and touch panel 13, described frame comprises shell 11 and circuit board 12, described shell 11, circuit board 12 and touch panel 13 superpose successively, be provided with electronic devices and components 14 and infrared receiving/transmission element 15 on the described circuit board 12, wherein, described infrared receiving/transmission element 15 is between described circuit board 12 and described touch panel 13.
According to touch-screen of the present utility model, infrared receiving/transmission element 15 is arranged between circuit board 12 and the described touch panel 13, namely be arranged on circuit board 12 below, rather than on circuit board 12, on the one hand because the infrared emission component in the infrared receiving/transmission element is sealed in the circuit board below, for example be sealed between circuit board and the touch panel 13, avoided the loss of the Infrared that infrared emission component sends, on the other hand, touch panel 13 is made by clear glass usually, infrared emission component be arranged on circuit board 12 below, can be returned infrared emission component by reflection of glass surface so that shine the light of glass surface in the Infrared that infrared emission component sends, thus so that the Infrared of sending reinforcement.
According to a kind of embodiment, described circuit board 12 can be arranged on the inboard at the edge of described touch panel 13.Like this, the successively circuit board 12 of stacking side frame and shell 11 above touch panel 13, rather than as prior art, frame is set to touch panel 13 outer and and touch panel 13 overlap.Wherein, described touch panel 13 is such as being made by materials such as clear glass or scale boards.Utilize this technical scheme, by being arranged on the frame of circuit board 12 inboard at the edge of touch panel 13, namely be arranged on the top of touch panel 13, rather than be arranged on the outside of touch panel 13, thereby no longer need to reserve the zone that overlaps with touch panel 13 at frame, reduce the width of frame, realized the touch-screen of super narrow frame.
According to another kind of embodiment, described circuit board 12 also can be arranged on the outside of described touch panel 13, for example can be connected with touch panel 13 by overlap joint.Like this owing to being arranged on the outside of touch panel 13 with the frame of circuit board 12, rather than be arranged on the top of touch panel 13, can reduce the height of frame, so that the thickness attenuation of touch-screen.
