Abstract: A touch module includes a touch sensor panel, a light guide plate, an adhesive layer and a shielding body. The touch sensor panel includes an opening. The adhesive layer includes a groove part. The light guide plate is located over the touch sensor panel. The adhesive layer is arranged between the touch sensor panel and the light guide plate. The touch sensor panel and the light guide plate are attached on each other through the adhesive layer. The groove part of the adhesive layer is in communication with the opening of the touch sensor panel to exhaust the gas. The shielding body surrounds the edge part of the light guide plate and the outer periphery part of the touch senor panel. Due to the shielding body, the light beam transferred in the light guide plate will not be leaked out.

Abstract: A light guide element includes a soft-light part and a light-transmissible part. The light-transmissible part is connected with the soft-light part. After plural light beams enters the soft-light part through a first soft-light part surface, the plural light beams are uniformly diffused by plural scattering particles of the soft-light part, and first-portion light beams of the plural light beams are exited from the soft-light part through a second soft-light part surface. The first-portion light beams enter the light-transmissible part through ae first light-transmissible part surface. A third light-transmissible part surface is a polished flat surface and arranged between the first light-transmissible part surface and the second light-transmissible part surface. After the first-portion light beams enter the light-transmissible part, a large proportion of the first-portion light beams are exited from the light-transmissible part through a second light-transmissible part surface.

Abstract: A computing device and an input device are provided. Each of the computing device and the input device includes a control unit, a light source, a projection plate and a casing. The control unit, the light source and the projection plate are accommodated within the casing. The light source emits light beams. The projection plate includes a pattern. After the light beams pass through the projection plate, the light beams are projected outside the casing and an image corresponding to the pattern of the projection plate is formed on a projection surface that is located outside the casing. Since the projection plate is cheap and small, the fabricating cost of the computing device or the input device is reduced and the purpose of developing the computing device or the input device toward light weightiness, slimness and small size is achievable.
