Abstract: An optical touch mouse includes a cover having a portion as a detect window, a lightguide adjacent to the detect window for directing light to the detect window, and a light source adjacent to the lightguide for providing light to enter the lightguide. The detect window is transparent to light provided by the light source such that light provided by the light source can penetrate through the detect window.

Abstract: An optical touch device includes a sensing area, at least a light source assembly and a light sensing component. The light source assembly is disposed beside the sensing area and includes a plurality of first point light sources configured to sequentially emit a first beam into the sensing area. The light sensing component has a field of view of the entire sensing area and is configured to sense the first beams. A light source assembly and a display module used in the optical touch device are also disclosed.
