LENS, BACKLIGHT MODULE AND DISPLAY APPARATUS HAVING THE LENS

摘要

PURPOSE: A lens, a backlight assembly with the same and a display device are provided to constitute the back light assembly with less number of light sources by evenly dispersing 'refracted rays through the lens' in a broader range. CONSTITUTION: /The upper flat surface(111) of a lens has the first radius. The bottom surface(112) of the lens has the second outer radius and the third inner radius. The internal curved surface(114) of the lens leads the light in being connected with 'an inner surface having the third inner radius of the bottom surface'. A diffusing plate contains multiple dot patterns to evenly disperse the light.
