Patent ID: 8714801

Claim:
An input device with multiple layers of luminous patterns, said input device comprising: an input interface, wherein a touching signal is generated when said input interface is triggered; a first light-emitting element for emitting a first light beam; a second light-emitting element for emitting a second light beam; and a light guide plate disposed over or under said input interface, and arranged between said first light-emitting element and said second light-emitting element, wherein said light guide plate comprises a plurality of first luminous patterns, a plurality of second luminous patterns and a gap between said first luminous patterns and said second luminous patterns, wherein said first light beam and said second light beam are respectively guided by said light guide plate, so that said first luminous patterns or said second luminous patterns are selectively visible, wherein said light guide plate further comprises an upper light-guiding layer and a lower light-guiding layer, wherein said gap is arranged between said upper light-guiding layer and said lower light-guiding layer, wherein said first luminous patterns are disposed on a first outer surface or a first inner surface of said upper light-guiding layer, and said second luminous patterns are disposed on a second outer surface or a second inner surface of said lower light-guiding layer.
