The frame has an opening for exposing the display surface. The optical touch-sensing units are disposed between the frame, the display surface and the side surface and define a sensing space upon the display surface. Each of the optical touch-sensing units has a sensing window facing to the sensing space, and senses an object in the sensing space through the sensing window.
