Abstract
An unevenly illuminated keyboard has a mask element between a luminous element and keycaps which are illuminated by the luminous element. The mask element has a permeable zone corresponding to each keycap and an impermeable zone on the neighboring area of the keycap but not beneath thereof such that the light emitted from the luminous element projects and illuminates the individual keycap to form the unevenly illuminated keyboard that illuminates only the keycaps.
Claims22
An unevenly illuminated keyboard comprising a base board having a top side and a bottom side, a plurality of keycaps movable up and down relative to the base board, the keycaps being on the top side of the base board, a circuit board for receiving compression from the keycaps to generate signal outputs, and a luminous element located between the top side of the base board and the keycaps to emit light to illuminate the keycaps, wherein:
- the keycaps and the luminous element are interposed by a mask element which has a permeable zone corresponding to each keycap and an impermeable zone on the neighboring area of the keycap but not beneath thereof such that the light emitting from the luminous element projects and illuminates the individual keycap to form the unevenly illuminated keyboard that illuminates only the keycaps.
