LIGHT DIFFUSION PLATE, A METHOD FOR MANUFACTURING A LIGHT DIFFUSION PLATE AND A BACKLIGHT ASSEMBLY HAVING THE SAME, CAPABLE OF REDUCING MANUFACTURING COSTS

摘要

PURPOSE: A light diffusion plate, a method for manufacturing a light diffusion plate and a backlight assembly having the same are provided to improve the slim of the light diffusion plate and luminance evenness by reducing an optical distance between a light source and a light diffusion plate.;CONSTITUTION: A base layer comprises a first side and a second side. The first side defines a plurality of unit dot area(DA01). The second side faces with the first side. An optical diffusion dot(130) is formed within the unit dot area. The optical diffusion dot is randomly formed on the first side while having an irregular area. The distribution of the optical diffusion dot is determined according to the shape of the unit dot area and a noise signal.;COPYRIGHT KIPO 2010
