Abstract
A backlight assembly includes a plurality of light sources emitting light and a diffusion plate. The diffusion plate includes an incident surface on which the light is incident, an exit surface which is opposite the incident surface and from which the light exits, and first and second lens patterns which are disposed on the exit surface and have different shapes from each other. Each of the first lens patterns includes a first curved portion which forms a curve and first linear portions which extend from both ends of the first curved portion, respectively. Each of the second lens patterns includes a second curved portion which forms a curve and second linear portions which extend from both ends of the second curved portion, respectively.
Claims20
A backlight assembly comprising:
- a plurality of a light source generating and emitting light;
- and
- a diffusion plate comprising:
- an incident surface on which the light is incident,
- an exit surface which is opposite the incident surface and from which the light exits, and
- a first group of a first lens pattern and a second group of a second lens pattern, both of which are disposed on the exit surface, and each of the first lens patterns having a different shape from the second lens patterns, wherein
- at least one of the first lens pattern and the second lens pattern comprises a curved portion which forms a curve and a linear portion extending from each of opposing ends of the curved portion, respectively.
A backlight assembly comprising:
- a plurality of a light source generating and emitting light;
- and
- a diffusion plate comprising:
- an incident surface on which the light is incident,
- an exit surface which is opposite the incident surface and from which the light exits, and
- a first group of a first lens pattern, a second group of a second lens pattern, and
- a third group of a third lens pattern, the first, second and third groups being sequentially repeated on the exit surface,
- wherein
- each first group of the first lens patterns overlaps a light source, and
- each of the second lens patterns has a different shape than each of the third lens patterns, and the second lens patterns are symmetrical to the third lens patterns about a boundary between the second group and the third group.
A backlight assembly comprising:
- a plurality of a light source generating and emitting light;
- and
- a diffusion plate comprising:
- an incident surface on which the light is incident,
- an exit surface which is opposite the incident surface and from which the light exits, and
- lens patterns, each of which is comprised of a curved portion disposed on the exit surface,
- wherein light diffusion patterns are disposed in an upper end of each of the curved portions.
A display device comprising:
- a plurality of a light source generating and emitting light;
- a display panel receiving the light from the light sources and displaying image information;
- and
- a diffusion plate comprising an incident surface on which the light is incident, an exit surface which is opposite the incident surface and from which the light exits, a first group of a first lens pattern and a second group of a second lens pattern, each group disposed on the exit surface and having different shapes from each other,
- wherein at least one of the first lens pattern and the second lens pattern comprises a curved portion which forms a curve and a linear portion extending from each of opposing ends of the curved portion, respectively.
