The monochromatic light-emitting module 1A and the monochromatic light-receiving module 1 are fastened to the edge position of the glass 13. The circuit board 12 includes a microcontroller 14 electrically connected to the monochromatic light emitting module 10 and the monochromatic light receiving module 11 for controlling the monochromatic light emitting module. 10 emits a monochromatic optical signal to the monochromatic light receiving module 11 to form a plurality of optical connections; and receives a signal from the monochromatic light receiving module 11 to discard the blocked optical connection. The microcontroller 14 transmits the blocked optical connection information to the main processing unit 2. The main processing unit 2 determines the position of the touched point based on the two mutually separated optical connection information. 3 is a schematic diagram of a touch electronic device according to a preferred embodiment of the present invention. In the example of 099107901, Form No. A0101, No. 5/17, 0992014174-0, 201133308, the monochromatic light emitting module 1 is exemplified.

The receiving tube 1 can be a photosensitive element receiving (e.g., a high-sensitivity photodiode) that changes the optical signal into an electrical signal that changes correspondingly with the change. When a light connection line corresponding to a transmitting tube 1〇 and a receiving tube is touched a little, the total reflection of the optical connection is destroyed, and the received light signal is abruptly weakened by the receiving tube. The microcontroller 14 can detect The electrical signal of the receiving tube 11 changes abruptly to determine that the optical connecting line corresponding to the transmitting tube 1 and the receiving tube 11 is cut.
