| Abstract |
A light guided plate coupled with the micro Fresnel lens array(MFLA) is designed to improve the efficiency of the LCD backlight unit. Blazed Frenel lens and binary multi-level Fresnel lens are adapted for the MFLA. This type of MFLA can replace the prism sheet and diffuser sheet which are used for the conventional type of the LCD backlight unit. The luminance and uniformity are calculated to verify the performance of the MFLA type LCD backlight unit. |
