Outer receptor 141.Wherein the 4th infrared remote receiver 141 is arranged on the 4th frame 14 uniformly.
The touching signals method of reseptance of the present invention can be as in figure 2 it is shown, touching signals method of reseptance that Fig. 2 is the present invention excellent
Select the flow chart of embodiment.The touching signals method of reseptance of this preferred embodiment includes:
Step S201, all infrared transmitting tubes send infrared beam successively；
Step S202, determines the infrared transmitting tube that infrared beam that each infrared remote receiver receives is corresponding；
Step S203, according to the signal transmitting and receiving relation of infrared remote receiver and infrared transmitter, creates all infrared beams
Trajectory diagram；
Step S204, according to the trajectory diagram of all infrared beams, determines the position of touch control operation；
Step S205, according to the position of touch control operation, determines the touching signals of correspondence.
The idiographic flow of each step of the touching signals method of reseptance of this preferred embodiment is described in detail below by Fig. 3.
In step s 201, all infrared transmitting tubes send infrared beam successively, such as on the first frame 11 in Fig. 3
The second infrared transmitting tube 121 on one infrared transmitting tube the 111, second frame 12 and the 3rd infrared emission on the 3rd frame 13
Pipe 131 sends infrared beam successively.Then pass to step S202.
In step S202, determine the infrared transmitting tube that infrared beam that each infrared remote receiver receives is corresponding.4th
Each 4th infrared remote receiver 141 on frame 14 can receive first infrared transmitting tube the 111, second infrared transmitting tube 121 and
The infrared beam of the 3rd infrared transmitting tube 131, may thereby determine that the infrared beam that each 4th infrared remote receiver 141 receives
The first corresponding infrared transmitting tube the 111, second infrared transmitting tube 121 and the 3rd infrared transmitting tube 131.Then pass to step
S203。
In step S203, the infrared remote receiver obtained according to step S202 and the signal transmitting and receiving relation of infrared transmitter,
Create the trajectory diagram of all infrared beams that all 4th infrared remote receivers receive.The most all infrared remote receivers and all infrared
Penetrate the track of infrared beam between pipe.Then pass to step S204.
In step S204, according to the trajectory diagram of all infrared beams that step S203 obtains, determine the position of touch control operation
Put.Infrared beam that is concrete, that can first not receive according to infrared remote receiver, determines the critical infrared beam received；Subsequently
According to all of critical infrared beam, determine the position of touch control operation；As shown in Figure 3 and Figure 4.
Refer to Fig. 3 and Fig. 4, when there is user's touch point 2 in contact panel, user's touch point 2 may result in
Four infrared remote receivers 141 cannot receive the infrared beam that at least part of infrared transmitting tube is launched, and so infrared connects according to the 4th
Receive device 141 and do not receive infrared beam to determine the position of user's touch point 2, receive red further according to the 4th infrared remote receiver 141
Outer light beam determines the size of user's touch point 2.
As having 20 infrared transmitting tubes, each 4th infrared remote receiver 141 should receive 20 articles under normal circumstances
Infrared beam, and by 20 infrared beam numbered 1-20 infrared beams.When there is user's touch point in contact panel,
4th infrared remote receiver 141 cannot receive 8-10 infrared beam, so can be by the 7th of the 4th infrared remote receiver 141 the
Number infrared beam and o.11 infrared beam are defined as critical infrared beam.Critical red by all 4th infrared remote receivers 141
Outer light beam can form a region after intersecting, and this region is the position of the position of user's touch point, i.e. touch control operation.The most true
The position of a fixed touch control operation or the position of multiple touch control operation.Then pass to step S205.
In step S205, according to the position of the touch control operation that step S204 obtains, determine the touching signals of correspondence.
The touching signals of the touching signals method of reseptance the most i.e. completing this preferred embodiment receives process.
The touching signals method of reseptance of this preferred embodiment relative to existing infrared remote receiver one to one with infrared
Transmitting tube, arranges multiple infrared remote receiver corresponding with multiple infrared transmitting tubes, even arranges all infrared remote receivers with all
Infrared transmitting tube corresponding.The track of the infrared beam between infrared remote receiver and all of infrared transmitter is the most, different
The track in direction is the most, so that it is determined that more critical infrared beam, and then make the profile of user's touch point close to true shape
Shape, thus improve the degree of accuracy of the touch screen shape to user's touch point and position.
Here the quantity of preferred infrared remote receiver is less than the quantity of infrared transmitting tube, because the cost of infrared remote receiver is higher than
Infrared transmitting tube, this setup has been greatly reduced the usage quantity of infrared remote receiver, and then has decreased product cost.
The precision of user's touch point is determined in order to improve the touching signals method of reseptance of the present invention, as it is shown in figure 5, Fig. 5
