Transflective frame and backlight module using the same

摘要

A backlight module ( 1 ) includes a light source ( 92 ), a light guide plate ( 80 ), and a frame ( 60 ). The frame contains the light source and the light guide plate. The frame includes a base plate ( 65 ) defining a transflective region ( 651 ) and a plurality of holes ( 652 ) defined in the transflective region. A portion of light beams from the light source is reflected by the transflective region out one main face of the backlight module, and a remainder of the light beams passes through the transflective region to emit from another main face of the backlight module. The backlight module and frame provide a double-sided emitting structure for a double-sided LCD. This avoids the need for an expensive transflector.
