Abstract
A backlight module includes a light source, a light guide plate, and a quantum dot enhancement film. The light guide plate has a light-incident side that faces toward the light source, a surrounding side that is connected to the light-incident side to constitute an outer periphery of the light guide plate, and a microstructure unit that is disposed adjacent to the surrounding side of the light guide plate. The quantum dot enhancement film is stacked on the light guide plate.
Claims26
A backlight module, comprising:
- a light source;
- a light guide plate having a light-incident side that faces toward said light source, a surrounding side that is connected to said light-incident side to constitute an outer periphery of said light guide plate, and a first microstructure unit that is disposed adjacent to said surrounding side of said light guide plate;
- and
- a quantum dot enhancement film stacked on said light guide plate;
- wherein said first microstructure unit includes a plurality of first microstructures, and said first microstructures include a plurality of protrusions having height-over-width ratios that decrease as a distance to said surrounding side of said light guide plate increases.
