Patent ID: 8692784

Claim:
A light-emitting touch keyboard, comprising: a reflecting sheet; a touch element, configured to receive touch input from a user and located over the reflecting sheet, wherein the touch element comprises two transparent material layers; a plurality of scattering/reflecting points, between the reflecting sheet and the touch element; and at least one light emitting element, adjacent to the touch element, for emitting a light ray to the transparent material layer, arranged such that the light ray penetrates the transparent material layer to the scattering/reflecting points and the reflecting sheet, and the reflecting sheet and the scattering/reflecting points reflect the light ray outside the touch element, wherein the transparent material layers are glass layers, the touch element further comprises a shielding layer, a sensing layer, an insulating layer, a signal wire, and an integrated circuit, the shielding layer is between the scattering/reflecting points and one of the transparent material layers, the sensing layer and the insulating layer are sequentially disposed between the transparent material layers, and the integrated circuit is located on a side edge of the insulating layer and electrical connected to the sensing layer through the signal wire.
