KEYBOARD STRUCTURE WITH A SELF-LUMINOUS CIRCUIT BOARD
First Claim
1. A keyboard structure, comprising a circuit board, and a plurality of key switch modules installed in said circuit board, each said key switch module comprising a frame and a press head vertically movably supported on said frame for pressing by a user to cause said circuit board to produce a respective electrical signal, wherein said circuit board comprises at least one flexible substrate made of a light guide material, a circuit layout arranged in said at least one flexible substrate, and luminous means mounted in said at least one flexible substrate and electrically connected with said circuit layout for emitting light upwards to illuminate said press heads of said key switch modules.
