Abstract
The utility model discloses a light guide diffusion plate. The light guide diffusion plate is provided with a transparent substrate. Several light guide spots are arranged on a back side of the transparent substrate. A right side of the transparent substrate is printed with a white ink layer with a rough external surface. Because the several light guide spots are arranged on the back side of the transparent substrate, a light guide function is possessed and a line light source can be converted into an area source. Because the external surface of the white ink layer is an uneven rough surface, a light diffusion function is possessed. Therefore, the light guide plate of the utility model possesses dual functions of the light guide and the light diffusion so that the line light source can be converted into the area source and the light is uniform and soft. Because the light guide diffusion plate of the utility model possesses the light diffusion function, a traditional diffusion plate can be avoided to be used. Because cost of the white ink layer with the rough external surface is lower than the cost of the traditional diffusion plate, by using the light guide diffusion plate of the utility model, the cost can be reduced. The white ink layer is printed on the light guide diffusion plate so that other fixed modes are not needed and the structure is simplified.
