Abstract: A display module includes a display panel; a backlight unit which is disposed behind the display panel; a bottom chassis to accommodate the backlight unit; and a reflective sheet which is disposed inside the bottom chassis and configured to reflect a light portion incident thereon toward the display panel. The backlight unit includes LEDs disposed apart from one another in 2D array, and the reflective sheet includes a sheet bottom portion corresponding to a front surface of the bottom chassis, a sheet inclined portion which is obliquely formed to face a rear surface of the display panel, and light adjustment portions which are provided on the sheet inclined portion and configured to adjust the light portion reflected by the sheet inclined portion. Each of the light adjustment portions corresponds to one of the LEDs disposed adjacent to the sheet inclined portion.

Abstract: A curved display apparatus includes a curved display panel, a curved bottom sash disposed at a rear of the display panel such that the curved bottom sash is spaced apart from the display panel, and a plurality of backlight units disposed at opposite inner sides of the bottom sash to irradiate light to the bottom sash. The inside of the bottom sash reflects the light irradiated from the backlight units to the display panel. Consequently, a light guide plate may be omitted from the display apparatus.

Abstract: A backlight unit and a display device having the same includes a light source installed at a position, separated from the central region of a light diffuser diffusing light by a predetermined distance, to radiate light to the light diffuser, and a lens unit installed between the light diffuser and the light source and having a surface facing the light source, the surface of the lens unit facing the light source including reflective areas which are coated with a reflective material and reflect a part of light radiated from the light source, and a transmissive area transmitting the other part of light radiated from the light source. The display device may eliminate generation of a dark region on a display panel due to the shadow of the backlight unit through improvement of the structure of the lens unit.
