Light guide module, optical touch module, and method of increasing a signal to noise ratio of an optical touch module |
摘要 |
A light guide module is applied in an optical touch module. A focusing component of the light guide module focuses the light emitted from a light guide component of the light guide module, so that all the light emitted from the light guide component can be convergently distributed in a touch area of the optical touch module. In this way, the light provided by a lighting component of the optical touch module can be effectively utilized, and the signal to noise ratio of the received signal of a sensor of the optical touch module increases. Therefore, the optical touch module can determines the location of the finger or the contacting object more correctly.
