A double-sided LCD panel is comprised of a transflective LCD panel and a light-emitting device. One surface of the transflective panel is used in the transparent mode, and the other surface is used in the reflective mode, achieving the goal of double-sided display. The light-emitting device may function as the front light source of the display surface in the reflective mode and the backlit source of the display surface in the transparent mode. In this manner, one can use a single panel for double screen display. This can simultaneously satisfy the requirements of light-weighted products and lowering the manufacturing cost.
