摘要： A method for manufacturing a light guide apparatus includes the following steps. A first mold and a second mold are provided. The first mold and the second mold respectively include a first molding surface and a second molding surface facing each other. A protrusion is disposed at the first or second molding surfaces. Sheet materials are provided. Each sheet material includes an opening corresponding to the protrusion, a first surface and a circuit layer disposed on the first surface. One of the sheet materials is disposed on the first mold with first surface facing the first mold. The first mold and the second mold are closed. An optical plastic material is injected into the space between the first and second molding surfaces to form a light guide plate having a via corresponding to the protrusion for embedding a light source. The sheet material is laminated on the light guide plate.

摘要： A light guide plate and assembly thereof are disclosed. The light guide plate includes a base plate, an optical pattern on the bottom surface of the base plate, a first circuit and a second circuit on the top surface of the base plate. As a front light module, the first circuit is designed to be light penetrable at the visual area of the base plate as a touch sensing circuit, and the second circuit is surrounding and electrically connected the first circuit. The front light module achieves the thickness reduction of a mobile device having a reflective type panel. As a back light module, the first circuit and the second circuit are arranged in two adjacent blocks on the top surface of the base plate without electrically connecting to each other. The back light module may be applied to perform a local dimming technology by adapting an extra low resolution panel.
