Patent attributes
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.
