摘要： A keyboard includes a base plate, a switch circuit board, plural swinging-type key structures, a light-emitting element, a light guide plate and a covering member. The light-emitting element emits a light beam. The plural swinging-type key structures are disposed on the switch circuit board. When one of the swinging-type key structures is pressed, the switch circuit board is triggered to generate a key signal. The light guide plate comprises plural light guide sub-plates. The light guide sub-plates are disposed on the corresponding swinging-type key structures. The covering member covers the base plate and the light guide plate. The covering member has a light-transmissible region. The light beam from the light-emitting element passes through the light-transmissible region. Consequently, the key structure is illuminated.

摘要： 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.

摘要： A luminous keyboard includes plural bottom-emitting type illumination elements, a sensing module, plural keys, and a light-transmissible supporting plate. As a key is moved toward the sensing module, the sensing module generates a corresponding non-contact key signal. Each bottom-emitting type illumination element is aligned with the corresponding key, and disposed under the corresponding key. The light-transmissible supporting plate is arranged between the plural bottom-emitting type illumination elements and the plural keys. After the light beam provided by each bottom-emitting type illumination element is transmitted through the light-transmissible supporting plate, the light beam is projected to the corresponding key.

摘要： Disclosed systems provide keyboard backlighting from organic light emitting diodes (OLEDs) placed under the keys. A keyboard stack optionally includes a light guide or reflector. A single OLED can illuminate multiple keys through a light guide. OLEDs used for backlighting may be arranged in a strip to illuminate more than one key. OLEDs can be deposited directly to the light guide or reflector, and can include a seal to promote air stability.

摘要： A luminous keyboard includes a lateral-emitting type illumination element, a light guide panel, a sensing circuit pattern, a light-transmissible supporting plate, and plural keys. 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 supporting plate 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 directed to the corresponding key. When one of the keys is moved toward the sensing circuit pattern, the sensing circuit pattern generates a corresponding non-contact key signal.

摘要： Backing lighting of induction touch keys is accomplished with a spacer layer surrounding an inductive touch sensor coil and a light source on a substrate, and light transmissive layer having a suspended metal disk proximate to the inductive touch sensor coil. A protective fascia may be placed over the light transmissive layer and spacer layer. When the light transmissive layer is displaced toward the inductive touch sensor coil the impedance value of the inductive touch sensor coil changes and the change is detected. Materials used that are translucent (light transmissive) may be continuous and solid, and opaque materials may have openings therein for transmission of light therethrough.

摘要： An operating device for electronic household appliances has a cover plate with an operating section that is elastically deformable and/or movable with the operating section. A carrier plate is arranged on a side of the cover plate facing away from a user side and at a spacing distance from the cover plate. A sensor on the carrier plate detects a distance variation from the inner side of the cover plate in the region of the operating section of the cover plate. A geometrically stable light guide element is furthermore provided, which extends in a region outside the operating section of the cover plate from the cover plate to the carrier plate. The cover plate has a signal section that is at least partially light-transmissive in the region of the light guide element.

摘要： A keyboard with a distance detecting function includes a plurality of keyswitches, and each keyswitch includes a keycap, a base, a supporting component, a recovering component and a distance detecting unit. The base has a guide slot structure. The supporting component has a first end connecting to the keycap, and a second end movably assembled with the guide slot structure. The recovering component is disposed between the supporting component and the guide slot structure. The distance detecting unit is detachably disposed on the base, and adapted to detect a movement of the keycap relative to the base for determining whether the keyswitch is actuated.
