A light guide plate includes a light incident surface to which light is incident as incident light, an opposite surface formed opposite to the light incident surface, a light emitting surface through which the incident light is emitted, a rear surface formed opposite to the light emitting surface and including a prism pattern which reflects the incident light to the light emitting surface, and lateral surfaces, wherein a diffuse reflection pattern is formed on at least any one of the light emitting surface and the lateral surfaces to diffuse-reflect light incident to the lateral surfaces, thus rendering a brightness at both the opposite surface and the light incident surface substantially uniform.
摘要:
In a light guide plate and a backlight assembly having the same, the light guide plate includes a plurality of light guide cells. Each light guide cell has at least one incident surface that receives light from an outside light source. The incident surfaces of the light guide cells are arranged in non-parallel planes. A light source unit includes at least one light source adjacent to the incident surface of each light guide cell. Thus, brightness of the backlight assembly is improved and thickness of the backlight assembly is reduced.

A display apparatus includes a display panel, a light source and a plurality of a light guiding plate. The LGP includes light incident, counter, light emitting and rear surfaces. The counter and rear surfaces are respectively opposite to the light incident and light emitting surfaces. The light emitting surface includes an ineffective light emitting area making contact with the light incident surface and an effective light emitting area connecting the ineffective light emitting area with the counter surface. The counter surface of a first light guiding plate is disposed overlapping the light incident surface of a second light guiding plate along a first direction, so that the rear surface partially overlaps with the effective light emitting area of the second light guiding plate, and the light guiding plates collectively form a light guiding plate array along the first direction.

A backlight assembly includes a light source, a light-guide plate, a reflective sheet, a first prism sheet, a second prism sheet and a lateral reflective sheet. The light source generates light. The light-guide plate guides the light and has a plurality of first prism patterns adjacent to each other. The first prism patterns are formed on a first surface of the light-guide plate. The reflective sheet is disposed adjacent the first surface of the light-guide plate. The first and second prism sheets are disposed on a second surface of the light-guide plate. The lateral reflective sheet is disposed on the second prism sheet. The lateral reflective sheet includes reflective protrusions substantially parallel with a longitudinal direction of the light source. Therefore, brightness and display quality may be enhanced.

A backlight assembly includes a light source, a light-guide plate (LGP), a reflective sheet and at least one optical sheet. The light source emits light. The LGP includes a light-incident surface, a light-reflecting surface and a light-emitting surface. The light-incident surface receives the light from the light source. The light-reflecting surface has a plurality of first prism patterns spaced apart from each other and flat portions formed between the first prism patterns, which are substantially perpendicular to the light-incident surface. The light-emitting surface has a plurality of second prism patterns formed thereon. The reflective sheet is disposed below the LGP. At least one optical sheet is disposed on the LGP.

A backlight assembly includes a first light source unit including n light emitting members; and a light guide plate including a first side adjacent to the first light source unit, and a first groove adjacent to a first end of the first side.
摘要:
A light guide plate includes an incident surface receiving incident light from a light source, an exit section that outputs exit light having a light distribution different from a light distribution of the incident light and a reflective section opposite to the exit section. A plurality of first patterns are formed on the exit section while being arranged in a first direction of the exit section to distribute the exit light with maximum brightness in a direction perpendicular to the exit section. A plurality of second patterns are formed on the reflective section to scatter the incident light.
