LIGHT GUIDE PANEL USING POLYGON PRISM DIFFUSING STRUCTURES FOR LCD BACK LIGHT UNIT AND LCD BACKLIGHT UNIT THEREBY

摘要

PURPOSE: A light guide panel using polygon prism diffusing structures for LCD back light unit and LCD backlight unit thereby are provided to improve brightness and regularity. CONSTITUTION: The body portion(20) comprises the side in which the light generating in the light source is income, and the front side radiating the light which is income in the side and the back side interviewing with the front side. The diffusion pattern(4) is arranged in the rear side of the body portion vertically and horizontally. The diffusion pattern diffuses the light incident to the body portion to the front side direction by the diffraction, and the refraction.
