  • Patent number: 10586888
    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.

  • Publication number: 20200004130
    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.

  • Patent number: 10410804
    Abstract: The present invention provides a multi-stage input device. The multi-stage input device includes a keycap, a multi-stage cushion component, and a circuit board assembly. The multi-stage cushion component is located between the keycap and the circuit board assembly to support the keycap. When the keycap is depressed to a light pressing level position, the keycap triggers a multi-stage switch of the circuit board assembly, so that the multi-stage switch generates a light-pressing signal to perform a first function. When the keycap is depressed to a heavy pressing level position, the keycap triggers the multi-stage switch of the circuit board assembly, so that the multi-stage switch generates a heavy-pressing signal to perform a second function.

  • Patent number: 10410807
    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.

  • Patent number: 10403788
    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.
