摘要： The present disclosure relates to a method for designing a light guide plate. A raw light guide plate having a light input surface and light output surface opposite to the light input surface is provided. An illuminating surface having a shape and area same to that of the light output surface is built. The illuminating surface is divided into n×m illuminating areas, and the light input surface is divided into n×m scattering dots distributing areas corresponding to n×m illuminating areas.

摘要： A light guide plate includes a body having a bottom surface and a light output surface opposite to the bottom surface. A reflector is located on the light output surface opposite to the center of the bottom surface. The reflector is a cavity concaved from the light output surface to the inside of the body. A plurality of scattering dots are located on the bottom surface. The scattering dots are arranged in the form of a plurality of concentric circles around the center of the bottom surface. The number of the scattering dots is defined based on a radius of the circle they reside on, and the radius of the circle is greater than or substantially equal to 4 millimeter.
