The present invention provides a luminous keyboard, including a key, a ring-shaped shading element, and a light source. The ring-shaped shading element is disposed between the key and the light source and is configured to shade light generated by the light source. When the key is pressed down, the key presses down the ring-shaped shading element and enables the ring-shaped shading element to be deformed, so as to prevent the ring-shaped shading element from affecting strokes of the key.

A push-button on a device includes a shell of the device, an internal locking portion to connect with the device, a touch pole far away from the locking portion, and a supporting flange portion extending from the internal surface of the shell. The supporting flange portion and the device support each other. When the shell is pressed, the push-button elastically deforms as the locking portion 103 acts as a fixing point and the supporting end acts as a supporting point. The touch pole moves with the shell and the switch on a PCB is triggered to generate at least one signal.

The present invention provides a luminous keyboard, including a key cap, a frame plate, and a light source. The frame plate is provided between the key cap and the light source for shielding light generated by the light source. The frame plate includes a plurality of openings for the light to pass through, and each opening is provided below the key cap. When the light passes through the opening, the light is illuminated on the key cap and the key cap is enabled to shine. In order to avoid the light being leaked out between the key cap and the opening of the frame plate, the opening is smaller than the press portion of the key cap.

A luminous keyboard includes a membrane wiring board, a key structure and a light-emitting element. The membrane wiring board includes a membrane switch. The membrane switch is electrically conducted through the key structure. The key structure includes a keycap, a connecting element and a soft light-shading element. The connecting element is arranged between the membrane wiring board and the keycap. The keycap is movable upwardly or downwardly relative to the membrane wiring board through the connecting element. The soft light-shading element is connected with the keycap and arranged around the connecting element. The at least one light-emitting element provides plural light beams. After first portions of the plural light beams are transmitted through the membrane wiring board, at least portions of the plural light beams are outputted from at least one light-transmissible region of the keycap. Consequently, the light utilization efficiency is enhanced.

A luminous keyboard includes plural keys, a light-emitting element, a light guide plate and a supporting plate. The light-emitting element emits light beams. The light guide plate includes plural light-guiding parts for guiding the light beams. The supporting plate includes a plate body, plural openings and plural sheltering walls. The openings run through the plate body and are aligned with the corresponding light-guiding parts. After the light beams are guided to pass through the openings by the light-guiding parts, the light beams are projected to the keys. The sheltering walls are disposed on the plate body and located beside the corresponding openings. The light beams and the light-guiding parts corresponding to the light beams are sheltered by the sheltering walls.

A computing system may include a keyboard and at least one backlight. The keyboard may include at least one key. The at least one key may include a first filter shaped according to a first character in a first alphabet. The first filter may transmit light within a first spectral range. The at least one key may also include a second filter shaped according to a second character in a second alphabet. The second filter may transmit light within a second spectral range. The at least one backlight may be configured to shine light of a first wavelength within the first spectral range in response to an instruction to display the first alphabet, and shine light of a second wavelength within the second spectral range in response to an instruction to display the second alphabet.

The present invention discloses a computer thin film switch keyboard, wherein the keyboard comprises keys/keycaps, a light guide film, a fixing film/air hole layer, metal domes, an air slot layer, a conductive film/PCB and a key plate, the key plate is disposed at the lowest layer, the conductive film/PCB is disposed above the key plate, the air slot layer is disposed above the conductive film/PCB, the metal domes are disposed on the conductive film/PCB, more than one metal dome is disposed corresponding to key configurations on the keyboard, the fixing film/air hole layer is disposed above the metal domes, and the keys/keycaps are disposed above the fixing film/air hole layer. The present invention has characteristics of being light, thin, and easy to carry, and having a Bluetooth function, a short stroke, and lower noises, etc.

In some implementations, a key structure may include a lower shell fixedly connected to a keyboard base. In addition, the device may include an upper shell assembled above the lower shell, where the upper shell is made of transparent plastic material, the upper shell is provided with having a through opening. The device may include a plurality of light guide columns extending downwardly from two sides of the bottom of the upper shell, where the plurality of light guide columns and the plurality of light-emitting sources are arranged opposite to each other. Moreover, the device may include a pressing shaft movably disposed between the lower shell and the upper shell, where a top end of the pressing shaft penetrates through the opening. Also, the device may include a spring disposed and elastically supported between the lower shell and the pressing shaft.

A display unit includes a layer with a plurality of sub-regions which are arranged adjacently to one another along an illuminated edge of the layer. A corresponding number of symbols are arranged in the sub-regions. The display unit additionally has a plurality of light sources. The said light sources are arranged adjacently to one another along the illuminated edge of the layer. Each light source is configured to emit light into the respective sub-region of the layer via the illuminated edge of the layer. The display unit additionally has a limiting element which is arranged between the illuminated edge of the layer and the light sources and which is configured to limit the light emitted from the light sources for each sub-region such that the symbol in the respective sub-region is illuminated in a selective manner by the light sources.

A light-emitting keyboard includes a bracket, keycaps, a circuit layer and a composite light-emitting layer. The keycaps are disposed on the bracket and connected to the bracket. The circuit layer is disposed between the keycaps and the bracket. The composite light-emitting layer is disposed under the bracket, and includes a substrate, a conductive layer and light sources. The substrate includes a connection portion and extension portions respectively connected to the connection portion. A gap is positioned between any two adjacent extension portions, and a width of the gap is greater than or substantially equal to a width of any of the two adjacent extension portions. The conductive layer is disposed on the substrate. The light sources are disposed on the extension portions.
