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 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 key structure includes a movable element, an elastic element, a light-emitting element and a pressure sensing element. The pressure sensing element is arranged between the elastic element and the light-emitting element. The elastic element is disposed on the movable element. The light-emitting element emits a light beam. The light beam is transmitted through the pressure sensing element and projected to the movable element to illuminate the key structure. While the key structure is depressed, the elastic element is pushed by the movable element. The pressure sensing element is pushed by the elastic element according to different magnitudes of the depressing force. Consequently, the key structure generates different pressure sensing signals.

Abstract: A luminous keyboard with a gaming function includes a gaming program, plural keys, plural light-emitting elements and a control unit. When one of the plural keys is pressed down, a corresponding pressing signal is generated. When one of the plural light-emitting elements is turned on to emit a light beam, the corresponding key is illuminated. The control unit is connected with the plural keys, the plural light-emitting elements and the gaming program. The control unit turns on or turns off the plural light-emitting elements according to settings of the gaming program. Alternatively, the control unit turns off the light-emitting element corresponding to the illuminated key when the control unit receives the pressing signal corresponding to the illuminated key. In such way, the luminous keyboard can be used to play a game.

Abstract: A luminous keyboard includes plural keys, a membrane switch circuit board and a light-emitting element. The membrane switch circuit board includes an upper wiring plate, a lower wiring plate, a conductor line pattern, a separation layer and an etched line pattern. The lower wiring plate includes a wiring plate opening. The conductor line pattern is arranged between the upper wiring plate and the lower wiring plate. The etched line pattern is arranged between the separation layer and the lower wiring plate. The etched line pattern is exposed through the wiring plate opening. The light-emitting element is electrically connected with the etched line pattern through the wiring plate opening in order to acquire electric power. Consequently, it is not necessary to install the illumination circuit board to provide the electric power to the light-emitting element.

Abstract: A luminous keyboard includes a lateral-emitting type illumination element, a light guide panel, a sensing circuit pattern, a light-transmissible substrate, a supporting plate, and plural keys. When one of the keys is moved toward the sensing circuit pattern, the sensing circuit pattern generates a corresponding non-contact key signal. The lateral-emitting type illumination element is used for providing a light beam to the light guide panel. Consequently, the light beam can be diffused to the whole light guide panel. The light guide panel has plural light-guiding dots for collecting and scattering the light beam. The light-transmissible substrate is arranged between the light guide panel and the plural keys, and has plural light diffusion structures corresponding to the plural keys. The light beam scattered upwardly by each light-guiding dot is sequentially transmitted through the corresponding light diffusion structure and the supporting plate and directed to the corresponding key.

Abstract: A luminous keyboard device includes plural keys, a supporting plate, a light-emitting element, and a light guide plate. The supporting plate has a supporting plate opening, and the supporting plate opening has a light-guiding slant surface. The light-emitting element is inserted into the supporting plate opening for emitting plural light beams. When the plural light beams are emitted by the light-emitting element, the plural light beams are guided by the light-guiding slant surface to be introduced into the light guide plate, and the plural light beams are directed to the plural keys to illuminate the plural keys. Consequently, the light amount of the light beams to be introduced into the light guide plate will be increased.

Abstract: An illuminated keyboard includes a light source, a key structure, and a backlight membrane switch module. The backlight membrane switch module is disposed under the key structure for generating a key signal and transferring a light beam from the light source to the key structure. The backlight membrane switch module includes a light guide plate and a membrane switch circuit board. The membrane switch circuit board is disposed over the light guide plate. Moreover, the membrane switch circuit board includes a wiring plate, a partition plate, and a light-shading part. The light-shading part is located at a side of the wiring plate or the partition plate, and bent downwardly to a position under the light guide plate in order to enclose a lateral surface of the light guide plate. Consequently, the problem of causing light leakage will be eliminated.
