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.

Abstract: A fingerprint identification module test system includes a light source, a projection surface, a low-end image pickup device and a judgment module. The light source emits and projects a light beam onto an under-test fingerprint identification module. After the light beam is reflected by the under-test fingerprint identification module and projected onto the projection surface, a projected image is formed on the projection surface. Then, the low-end image pickup device photographs the projected image to acquire an under-test corresponding to the under-test fingerprint identification module. According to the result of comparing the under-test image with the predetermined image, the judgment module judges whether the under-test fingerprint identification module complies with the production specifications. Since the fingerprint identification module test system uses parity devices to test the under-test fingerprint identification module, the fingerprint identification module test system is cost-effective.

Abstract: A keyboard device includes a key, a base plate, a membrane circuit board and a buffering part. The membrane circuit board is disposed on the base plate. The key includes a keycap and a stabilizer bar. The stabilizer bar is connected between the keycap and the base plate. The stabilizer bar includes a main bar part, a first linking part and a first insertion part. The first linking part is connected between the main bar part and the first insertion part. The buffering part is disposed on the base plate or the membrane circuit board and located under the first linking part. While a keycap is moved downwardly relative to the base plate, the linking part of the stabilizer bar is contacted with the buffering part. The contact point between the linking part of the stabilizer bar and the buffering part is used as a fulcrum.

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: A keyboard device includes a base plate, a butterfly-type connecting element and a keycap assembly. The keycap assembly includes a coupling frame and a keycap. The coupling frame includes a first coupling part. The keycap includes a second coupling part. The butterfly-type connecting element is connected with the base plate and the coupling frame. The coupling frame and the butterfly-type connecting element are combined together through the first coupling part and the second coupling part. When the pressing force is acted on a corner of the keycap, the pressing force can be transferred to the whole keycap through the coupling frame. Consequently, the pressing force can be effectively transferred.

Abstract: A touch module includes an upper plate, a lower plate, a hinge structure, an elastomer and a touchpad assembly. The touchpad assembly is located over the upper plate. A first end of the upper plate and a first end of the lower plate are pivotally coupled to each other through the hinge structure. While the touchpad assembly is pressed down, a second end of the upper plate is swung downwardly relative to a second end of the lower plate and a switch element of the touchpad assembly is triggered. When the touchpad assembly is no longer pressed, the elastomer provides an elastic force to the upper plate. In response to the elastic force, the second end of the upper plate is swung upwardly relative to the second end of the lower plate and the touchpad assembly is returned to an original position.

Abstract: The present invention relates to a luminous keyboard, including a key, a support plate, a switch circuit board, a light guide plate, and a direct-type light emitting element capable of generating a beam. The support plate is located below the key, and the switch circuit board is disposed on the support plate. The light guide plate is located below the support plate and includes a concave structure, and the concave structure forms a reflective surface inside the light guide plate. The direct-type light emitting element is located below the concave structure. When the beam enters the light guide plate, the beam is reflected by the reflective surface to be fully reflected in the light guide plate, and the light guide plate guides the beam to be projected to a peripheral area of a key.
