Abstract
A backlight module (70) includes a light guide plate (72), a light source (74), a micro reflector array (723), and a reflector (76). The light guide plate includes a light input surface (722) facing the light source, a light output surface (724) adjacent to the light input surface, and a reflective surface (726) opposite to the light output surface. The light source and an emitting surface (744) thereof both face the light input surface. The micro reflector array and the reflector are configured for cooperatively coupling a first portion of the light beams into the light input surface via any corresponding microgap and reflecting a second portion of the light beams into the light guide plate at a location distant from the light source.
