| Zusammenfassung: | The utility model discloses a touch sensing system. The optical module comprises a transparent substrate, at least one light emitting assembly and at least one light receiving assembly, the light emitting assembly is arranged at the first side edge and the second side edge; the light emitting assembly is further provided with at least one first parallel light module and at least one first refracted light module, the light receiving assembly is arranged at the positions of the third side edge and the fourth side edge, and the light receiving assembly is further provided with at least one secondparallel light module and at least one second refracted light module. According to the touch transparent substrate, the total reflection light can be effectively shielded, the light intensity in thetransparent substrate is attenuated, the touch position of the touch transparent substrate is judged through the light receiving piece and transmitted through the transparent substrate in a total reflection light mode, the tot |
