Abstract
A multicolor illumination keyboard includes a light-emitting element, a color filter and plural keys. The plural keys are located above the light-emitting element. The color filter is arranged between the plural keys and the light-emitting element. After a source light emitted by the light-emitting element passes through the color filter, plural color lights are generated. The plural color lights are outputted from the plural keys. Consequently, the plural keys are illuminated in a multicolor manner.
Claims11
A multicolor illumination keyboard, comprising:
- a light-emitting element emitting a source light to the multicolor illumination keyboard;
- a color filter located above the light-emitting element, and allowing the source light to pass through, wherein the color filter comprises plural filtering regions, and plural color lights are generated after the source light passes through the corresponding filtering regions;
- plural keys disposed over the color filter, wherein each key comprises a keycap, and the keycap comprises plural light-transmissible regions, wherein after the plural color lights pass through the corresponding light-transmissible regions, the plural color lights are outputted from the key;
- and
- plural elastic elements, wherein each of the plural elastic elements is aligned with the corresponding keycap, and the key is returned to an original position in response to elasticity provided by the elastic element, wherein the plural elastic elements are disposed on the color filter, and the plural elastic elements and the color filter are collaboratively formed as a flexible color filter layer.
