Abstract
An electronic device with an optical touch module is presented. A touch pad is disposed on the electronic device and at least one light transmission element is disposed on at least one side of the touch pad. The touch pad has a sensing area and senses a moving track direction of an object on the sensing area. Therefore, the touch pad, according to the moving track direction of the object, activates a light source to irradiate to the light transmission element corresponding to the moving track direction, such that the light transmission element illuminates on at least one side of the touch pad, thus achieving the effect of direction indication with light sources.
