摘要： An optical touch device includes a transparent substrate and at least a light emitting and receiving unit. The transparent substrate has a touch surface, a first light incidence surface and a first light emitting surface. Each light emitting and receiving unit includes a linear light source, a light path adjusting component and a light sensing component. The linear light source is disposed beside the first light incidence surface. The light path adjusting component is disposed between the linear light source and the first light incidence surface and configured for adjusting the incidence angles of the optical signals striking at the first incidence surface so that each of the optical signals enters into the transparent substrate through the first incidence surface with a predetermined angle. The light sensing component is disposed beside the first light emitting surface. The optical touch device has a high light utility efficiency.

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.
