Abstract: A multi-functional keypad module for a mobile phone includes a circuit board, a light-emitting element, a soft light-guiding rubber layer, an optical touch layer, and a key layer. The soft light-guiding rubber layer is provided on the circuit board and has a plurality of protrusions each corresponding to the circuit board; thereby a feedback feeling from a pressing action and a light-guiding effect can be obtained. The optical touch layer is provided on the soft light-guiding rubber layer, in order to continue the optically enhanced touch-control and the feedback feeling. The key layer is provided on the optical touch layer, with a plurality of keys respectively corresponding to one of the protrusion, thereby completes and achieves the optically enhanced touch-control effect and feedback feeling. Via the above arrangement, the keypad module of a mobile phone has multiple functions of light guiding, touch-control, and feedback feeling from a pressing action.

Abstract: A super-thin light-guiding module with a side light-projecting function includes: a transparent elastic element, at least one light-emitting element, a displaying layer, and an elastic filling layer. The transparent elastic element has a plurality of light-guiding microstructures formed on a bottom thereof. The light-emitting element is disposed beside one side of the transparent elastic element. The displaying layer is disposed on a top side of the transparent elastic element, and the displaying layer has a plurality of transparent portions. The elastic filling layer is disposed between the transparent elastic element and the displaying layer. Therefore, when the light-emitting element projects a light to the transparent elastic element, the light is guided upward via the light-guiding microstructures of the transparent elastic element for making the light pass through the elastic filling layer and the transparent portions of the displaying layer.
