高輝度複合式導光板之背光模組應用

Abstract

本論文中，我們介紹一種新型的背光模組。此新型背光模組由複合式導光板、增亮膜和上擴散片所組成。該複合式導光板結合了傳統背光模組之導光板、反射片和增亮膜的功能，可以讓光線一維度的準直。此外，我們在複合式導光板的上方，加一層增亮膜，使光線在垂直維度也可以準直。和傳統的邊光式背光模組比較，新型背光模組的出光量可以提升至1.3倍，正向輝度可以提升3.6倍。

We introduce the novel backlight module, which consists of the hybrid light guide plate, brightness enhancement film and a top diffuser. The HLGP comprises the functions of the conventional light guide plate, the reflector, and the BEF. The HLGP allows one-dimensional rays to be collimated. We add the BEF above the HLGP, and let the crossed-dimension rays to be collimated. Comparing with the conventional edge-lit backlight module, the optical efficiency improves to 1.3-times and the on-axis luminance improves to 3.6-times by using the novel backlight module.
