Patent ID: 8404984

Claim:
A lighted keyboard comprising: a plurality of transparent, rectangular keys each comprising a bottom stem; a plurality of scissors shaped structures disposed under the keys, each scissors shaped structure being aligned with the stem and comprising a first frame and a second frame pivotally secured together; an OLED sheet disposed under the scissors shaped structures and comprising a plurality of units each including a hole; an optically transmissive rubber plate disposed under the OLED sheet and comprising a plurality of units each including a resilient dome passing through the hole of the unit of the OLED sheet, the resilient dome having a conductive shaft aligned with the stem; a membrane circuit board disposed under the rubber plate and comprising a plurality of contacts each aligned with the conductive shaft; and a rectangular aluminum plate disposed under the membrane circuit board and comprising a plurality of units each including a plurality of snapping grooves and a slide guide groove; wherein the corresponding snapping grooves, the slide guide groove, and the scissors shaped structure are secured together; wherein on the bottom of the key there are further provided two pivot grooves and two slide guide grooves; wherein the pivot grooves and the slide guide grooves are secured to the scissors shaped structure; wherein the scissors shaped structure comprises two first slide axles at two corners of the first frame, two second pivot shafts at two corners of the second frame, the second pivot shafts being below the first slide axles, a first pivot shaft at the other side of the second frame, a second slide axle at the other side of the first frame parallel to and below the first pivot shaft, and a central circular hole; wherein the first slide axles are slidably secured to the slide guide grooves and the first pivot shaft is rotatably secured to the pivot grooves respectively; wherein the snapping grooves of each unit of the aluminum plate are adapted to retain the second pivot shafts, and the slide guide groove of each unit of the aluminum plate is adapted to retain the second slide axle; and wherein the OLED sheet is a FOLED (flexible organic light emitting diode) comprising a plurality of units each including a plurality of openings with the second slide axle and the second pivot shaft of the scissors shaped structure being disposed therein, and a circular hole with the resilient dome passing through.
