Patent ID: 10497522

Abstract:
A luminous keyboard comprises a key assembly, a thin-film switch circuit board assembly, a base plate and a light guide plate. The key assembly is disposed on the thin-film switch circuit board assembly. The thin-film switch circuit board assembly is disposed on the base plate. The base plate is disposed on the light guide plate. The base plate and the light guide plate together form an aperture structure. The thin-film switch circuit board assembly includes a thin-film switch circuit board and a light-emitting unit. The thin-film switch circuit board forms a protrusion protruding toward the aperture structure. The light-emitting unit is disposed at the bottom surface of the protrusion and extends downward such that a lower end of the light-emitting unit is lower than a lower surface of the base plate so that the light-emitting unit emits light into the light guide plate directly.
