ABSTRACT
In order to make the backlight system thinner and brighter, we propose a high quality poly(methylmethacrylate) light guide plate (LGP) based on microprism structures, which can be designed to control the illumination angle, and to get enough uniformity of intensity, so the backlight system will be simplified to use only one LGP and requires no other optical sheets. Design results reveal that our LGP can achieve a uniformity of intensity better than 86%, and get an illumination angle between ±25°, without using any optical sheets.
