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.

Illuminant human interface device

A keyboard structure includes a light guide plate, a circuit board and a key sheet sequentially disposed on a reflecting sheet. A plurality of scattering and reflection points is located under the light guide plate and at least one light-emitting element on one side of the light guide plate. The key sheet has a one-piece formed body and a plurality of pressing portions. The plurality of pressing portions may be actuated to shift and conduct a sensor on the circuit board. Each pressing portion further has a light transmissive area. A light ray emitted by the light-emitting element passes through the light guide plate, and is reflected by the reflecting sheet to the light guide plate and the key sheet. Then, the light ray comes out of the key sheet through the light transmissive areas of the pressing portions.
