    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 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： 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： A physical force capacitive touch sensor comprises a capacitive sensor element on a substrate, a physically deformable electrically insulating spacer over the capacitive sensor element and a conductive plane over the physically deformable electrically insulating spacer. A protective fascia may be placed over the conductive plane provides an environmental seal for physical and weather protection, but is not essential to operation of the capacitive touch sensor. Back lighting is accomplished with a light transmissive layer having a suspended metal target proximate to the capacitive touch sensor plate. When the light transmissive layer and metal target are displaced toward the capacitive touch sensor plate the capacitance value of the capacitive touch sensor plate changes and that change is detected.
