PRINT TYPE LIGHT GUIDE PANEL

摘要

PURPOSE: A print type light guide panel is provided to obtain relatively higher luminance by increasing the amount of light reflected on the entire surface of the light guide panel. CONSTITUTION: A print type light guide panel includes reflection elements printed on a background surface(41) except portions with dots(42) in the circular, polygonal, or both circular and polygonal shape, wherein the non-printed dots become smaller or an interval between the non-printed dots becomes larger toward remote portions from a light source, thereby increasing the printing density.
