    摘要： An input device comprising an optical module having a light guide plate, a light source, a scattering layer and a sensor is provided. The light guide plate has a top surface, a bottom surface, and a side. The light source emits a light to the side. The light travels within the light guide plate. The scattering layer changes a path of parts of the light on the bottom surface so that the light is projected out of the top surface to form a penetrating light. When an object approaches or touches the top surface of the light guide plate, at least a part of the penetrating light is reflected by the object to form a reflected light received by the sensor. According to the reflected light, the input device generates a position signal indicating at least one relative position of the object with respect to the top surface.
