Abstract
A backlight unit includes first light guide plates (LGPs) provided in a line shape, and second LGPs provided in a line shape and disposed between the first LGPs. The backlight unit may include a controller configured to control a plurality of light sources to provide a light to the first LGPs when a three-dimensional (3D) image is displayed on a display panel that receives the light from at least one of the first LGPs and the second LGPs, and to provide the light to the first LGPs and the second LGPs when a two-dimensional (2D) image is displayed on the display panel.
Claims17
A backlight unit comprising:
- first light guide plates (LGPs) provided in a line shape;
- second LGPs provided in a line shape and disposed between the first LGPs;
- and
- a controller configured to control a plurality of light sources to provide light to the first LGPs if a three-dimensional (3D) image is being displayed on a display panel, and to provide light to the first LGPs and the second LGPs if a two-dimensional (2D) image is being displayed on the display panel,
- the display panel including at least a first area and a second area,
- the controller being further configured such that, when the 3D image is being displayed on the first area of the display panel while the 2D image is being displayed on the second area of the display panel, the controller controls the plurality of light sources to,
- provide light to LGPs, from among the first LGPs, that correspond to the first area of the display panel, and
- provide light to LGPs, from among the first LGPs and second LGPs, that correspond to the second area of the display panel.
A backlight unit comprising:
- a light guide plate (LGP) including first light guide elements in a line shape and second light guide elements in a line shape, and the second light guide elements being between the first light guide elements;
- and
- a controller configured to control a plurality of light sources to provide light to the first light guide elements if a three-dimensional (3D) image is being displayed on a display panel, and to provide light to the first light guide elements and the second light guide elements if a two-dimensional (2D) image is being displayed on the display panel.
A display device comprising:
- first light guide plates (LGPs) provided in a line shape;
- second LGPs provided in a line shape and disposed between the first LGPs;
- a display panel configured to display at least one of a two-dimensional (2D) image and a three-dimensional (3D) image;
- and
- a controller configured to control a plurality of light sources to provide light to the first LGPs if the 3D image is being displayed on the display panel, and to provide light to the first LGPs and the second LGPs if the 2D image is being displayed on the display panel,
- the display panel including at least a first area and a second area,
- the controller being further configured such that, when the 3D image is being displayed on the first area of the display panel while the 2D image is being displayed on the second area of the display panel, the controller controls the plurality of light sources to,
- provide light to LGPs, from among the first LGPs, that correspond to the first area of the display panel, and
- provide light to LGPs, from among the first LGPs and second LGPs, that correspond to the second area of the display panel.
