Abstract
A light-emitting touch keyboard includes a reflecting sheet, a touch element, a plurality of scattering/reflecting points, and at least one light emitting element. The touch element includes at least one transparent material layer. A light ray emitted by the light emitting element penetrates the transparent material layer, and then is reflected outside the touch element by the reflecting sheet and the plurality of scattering/reflecting points.
