Abstract
The invention discloses a light guide diffusion plate which is provided with a transparent substrate. A plurality of light guide points are arranged on the back side of the transparent substrate, and a white ink layer with a rough outer surface is printed on the front side of the transparent substrate. As a plurality of light guide points are arranged on the back side of the transparent substrate, the light guide diffusion plate has the function of light guide to convert the line source into surface source; and as the outer surface of the white ink layer is a rough surface, the light guide diffusion plate has the function of light diffusion. Therefore, the light guide plate has double functions of light guide and light diffusion to convert the line source into surface source and enable the light more even and soft. Besides, as the light guide diffusion plate has the function of light diffusion, a white ink layer with a rough outer surface can be used instead of a traditional diffusion plate which is higher in cost, thereby the cost is reduced. In addition, the white ink layer is printed on the light guide diffusion plate without adopting other fixing ways, thereby the structure is simplified.
