See also Fig. 1, known touch panel detection device is to comprise a substrate 1, this substrate 1 has a plurality of transmitters 10 and a plurality of receiver 11, this substrate 1 surrounding is provided with described transmitter 10 and receiver 11, its arrangement mode is into the infrared-type touch matrix of the corresponding receiver 11 of a transmitter 10, so can cause the huge LED module transmitter 10 of quantity and receiver 11.Seeing also Fig. 2, is the infrared ray that utilizes a receiver 11 and a plurality of transmitters 10 of reception to send, and whether a plurality of transmitters 10 are launched in proper order, then be cut off by these receiver 11 identification optical paths again.Seeing also Fig. 3, is to utilize a transmitter 10 and a plurality of receiver 11 to form a plurality of infrared ray lines; Due to aforesaid arbitrary substrate 1, all because setting a touch point on each optical path, more a plurality of touch points are set in the space that can't take full advantage of on optical path, and and fail the efficient space that utilizes on substrate 1, in addition, also can cause the generation that has dead angle on substrate 1.

The above, known technology has following shortcoming:

1. have the generation at dead angle;

2. touch-control is fuzzy indefinite;

3. the efficiency of substrate space utilization is lower.

Therefore, how to solve above-mentioned public problem and disappearance, the inventor who is this case desires most ardently to the relevant manufacturer that is engaged in the industry the direction place that research improves.

Summary of the invention

For this reason, for effectively solving the above problems, fundamental purpose of the present invention is to provide a kind of touch panel detection device that improves the Dead Core Problems of known substrate generation.

Secondary objective of the present invention, be to provide a kind of touch panel detection device that can efficiently utilize the space on substrate.

for reaching above-mentioned purpose, this creation provides a kind of touch panel detection device, comprise a substrate, at least one the first transmitter, at least one the second transmitter, at least one the first receiver and at least one the second receiver, the all sides of described substrate are extended respectively a first side and a second side and one the 3rd side and a four side, described first, dual side-edge is mutually corresponding, the described the 3rd, four side is mutually corresponding, described first, dual side-edge is respectively equipped with at least one the first fixed part and at least one the second fixed part, the described the 3rd, four side is respectively equipped with at least one the 3rd fixed part and at least one the 4th fixed part, described first, two fixed parts are parallel and the dislocation correspondence, the described the 3rd, four fixed parts are parallel and the dislocation correspondence, described the first transmitter is arranged at aforementioned the first fixed part, described the second transmitter is arranged at aforementioned the 3rd fixed part, described the first receiver is arranged at aforementioned the second fixed part, described the second receiver is arranged at aforementioned the 4th fixed part.

by aforesaid touch panel detection device, due to aforesaid first, two transmitters and first, two receivers are configuration mode parallel and that dislocation is corresponding, thus, when described first, the infrared ray optical path that two transmitters send can contain corresponding first, two receiver range of receiving, improved known transmission device and the receiver mode because of parallel and corresponding setting, make infrared ray optical path that the known transmission device sends only vertical correspondence be projected to corresponding receiver and can't receive the dead angle puzzlement that detecting produces on a large scale, and then substrate space more can efficiently be utilized, and improve the indefinite problem of dead angle and touch-control.
