Abstract
A backlight assembly and an LCD apparatus capable of reducing power consumption and increasing brightness of a light. The backlight assembly includes a light guide plate for receiving an external light and an artificial light, a first receiving container for receiving the light guide plate and supplying the artificial light to the light guide plate, and a second receiving container for supplying the external light to the light guide plate, the second receiving container comprising an light side wall inclined to the light guide plate. The LCD panel assembly displays images using the external light and artificial light from the light guide plate.
Claims22
A backlight assembly comprising:
- a light guide plate including a first side surface for receiving an external light, a second side surface for receiving an artificial light, a third side surface and a fourth side surface for connecting the first side surface to the second side surface, a light reflecting surface for reflecting the external light and the artificial light, and a light emitting surface facing the light reflecting surface;
- a first receiving container for receiving the light guide plate and for supplying the artificial light to the second side surface, the first receiving container comprising first, second, and third sidewalls for covering the second to fourth side surfaces of the light guide plate;
- and
- a second receiving container comprising a bottom surface, fourth, fifth, and sixth sidewalls for covering the first, second, and third sidewalls, and a light sidewall for supplying the external light to the first side surface, wherein the lighting sidewall is extended from the bottom surface, inclined with respect to the first side surface, and connected between the fifth and the sixth sidewalls.
A backlight assembly comprising:
- a light guide plate including an external light-lighting body having a light reflecting side surface for reflecting an external light from a first direction to a second direction, a light receiving surface for receiving an artificial light from a third direction, a light reflecting surface for reflecting the external light and the artificial light to a fourth direction, at least one side surface adjacent to the light receiving surface, and a light emitting surface for emitting the external light and the artificial light having the fourth direction;
- a first receiving container including a first sidewall for covering the light receiving surface and the side surface, wherein the first receiving container supplies the artificial light to the light receiving surface;
- a second receiving container including a bottom surface, a second sidewall extended from the bottom surface, and a lighting sidewall extended from the bottom surface and connected to the second sidewall, wherein the lighting sidewall is inclined with respect to the bottom surface;
- and
- a light reflecting means disposed over the lighting sidewall and the bottom surface.
An LCD apparatus comprising:
- a backlight assembly including a light guide plate for receiving an external light and an artificial light, a first receiving container for receiving the light guide plate and supplying the artificial light to the light guide plate, and a second receiving container for supplying the external light to the light guide plate, wherein the second receiving container includes a lighting sidewall being inclined with respect to the light guide plate;
- an LCD panel assembly for converting the external light and the artificial light into an image light having image information;
- and
- a chassis including a chassis body for exposing an effective display area of the LCD panel assembly and an external light-inducting window disposed on a portion of the chassis body and corresponding to the lighting sidewall, wherein the chassis is combined to the second receiving container so as to fix the LCD panel assembly to the second receiving container.
