Abstract: A touch display device includes a display panel and a touch-sensitive board. The touch-sensitive board includes an anti-glare structure and a touch-sensitive membrane. The anti-glare structure is used for inhibiting glare. The touch-sensitive membrane is disposed on a surface of the anti-glare structure for sensing the positions of the user's fingers or other indicants. Since the touch-sensitive membrane is disposed on the anti-glare structure, it is not necessary to provide an additional plastic substrate to install the touch-sensitive membrane thereon. Consequently, the thickness of the touch display device can be reduced.

Abstract: A manufacturing method of a light source module includes the following steps. Firstly, a light emitting diode die is installed on a supporting base. Then, an electric connection between the light emitting diode die and the supporting base is established. Then, a protective glue is formed on the light emitting diode die and the supporting base. Afterwards, the supporting base is cut to produce the light source module. Since the supporting plate is not employed, the supporting plate removing process and the boning process of the conventional technology are omitted. Consequently, the manufacturing method of the present invention is effective to enhance the production quality of the light source module.

Abstract: A cooling fan includes a fan base, an impeller part, a driving part, an illumination circuit board and plural light-emitting elements. The driving part includes a shaft seat, a driving circuit board and plural coils. The driving circuit board is disposed on the fan base. The plural coils are arranged between the driving circuit board and the illumination circuit board and arranged around the shaft seat. The rotating shaft of the impeller part is inserted into the shaft seat. When an electric current flows through the plural coils, the rotating shaft is rotated. The plural light-emitting elements are disposed on the illumination circuit board. When the electric current flows through the plural light-emitting elements, the plural light-emitting elements emit light beams.

Abstract: A luminous keyboard includes a key structure, a supporting plate, a switch circuit board, a light guide plate and a top-view light-emitting element. The supporting plate includes an opening. The top-view light-emitting element emits a light beam. The supporting plate is located under the key structure. The switch circuit board is located over the supporting plate. The light guide plate is located under the supporting plate and includes a light guide plate opening. The top-view light-emitting element is inserted into the opening. After the light beam is transmitted through the opening, a first-portion beam of the light beam is transmitted through the switch circuit board and projected to a first region of the key structure. A second-portion beam of the light beam is sequentially blocked by the switch circuit board, introduced into the light guide plate, and guided to a second region of the key structure.

Abstract: A light source module includes a substrate, a first covering layer, a second covering layer, a luminous layer and a supporting base. The luminous layer is arranged between the first covering layer and the second covering layer. The luminous layer emits a light beam in response to a first current flowing through the first covering layer and a second current flowing through the second covering layer. The light beam is projected to surroundings through the substrate. The supporting base is electrically connected with the first covering layer and the second covering layer. The supporting base includes a circuit board and a passivation layer. When a portion of the light beam projected to the supporting base is reflected by the passivation layer, the portion of the light beam is projected to the surroundings through the substrate.

Abstract: An input device with an adjustable force level is provided. The input device includes a circuit board and a key structure. The key structure includes a key body, a casing and a pressure-adjustable elastic receptacle. The pressure-adjustable elastic receptacle is partially or completely accommodated within the casing and sustaining the key body. When the key body is moved downwardly, a resisting force to resist the key body is provided by the pressure-adjustable elastic receptacle and the force level of the resisting force is adjusted by the user. When a force with the force level is applied to the key body by the user, a switch of the circuit board is triggered.
