Abstract
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.
Claims18
A frame used in a backlight module, comprising:
- a base plate defining a transflective region;
- and
- a plurality of holes defined in the transflective region;
- wherein a portion of light beams from a light source is reflected by the transflective region, and a remaining portion of the light beams is transmitted through the transflective region via the holes.
The frame as claimed in claim 4, wherein a diameter of the holes progressively increases along a direction away from a side of the base plate.
A backlight module, comprising:
- a light source;
- a light guide plate;
- and
- a frame comprising a base plate which defines a transflective region, the frame containing the light source and the light guide plate;
- wherein the transflective region defines a plurality of holes therein, a portion of light beams received from the light source is reflected by the transflective region, and a remaining portion of the light beams is transmitted through the transflective region via the holes.
A display device comprising:
- a light source assembly installable in said display device and capable of providing light for said display device along a preset surface in said display device;
- and a frame installable in said display device next to said light source assembly, said frame comprising a transflective region extending along said preset surface to accept said light from said light source assembly so as to partially reflect said light at a part of said region and partially transmit said light through said region without reflection of said light at another part of said region.
