Abstract:
A backlight unit including a frame having a bottom area and a sidewall area extended from the bottom area; a single substrate located in on the bottom area of the frame, a plurality of optical assemblies being mounted on the single substrate; a reflection sheet located the frame and configured to reflect light emitted by the optical assemblies; and an optical sheet located over the reflection sheet. Further, the reflection sheet a first sheet area corresponding to the bottom area of the frame; a second sheet area corresponding to the sidewall area of the frame; and a cut portion cut from the first sheet at one portion abutting on one side of the single substrate.
Abstract:
A backlight unit and a display device having the same are provided. The backlight unit includes a light source, a reflector arranged on and under the light source to totally reflect at least a part of light emitted from the light source in a lateral direction, a reflective sheet arranged under the reflector, and a diffusion sheet arranged on the reflector.
Abstract:
An optical lens and a display device including the same are provided. An optical lens includes a first surface having a circular cross-sectional shape, a second surface opposite to the first surface, and a third surface configured to connect the first surface and the second surface. The third surface includes a straight surface extending from a boundary of the first surface and a first curved surface extending from the straight surface to the second surface. The straight surface and the first curved surface extending in a path between the first surface and the second surface. The second surface includes a concave recess recessing in a direction of the first surface and the concave recess includes a second curved surface. Light that has passed through the second concave surface changes a path as the light passes through the first curved surface such that light path can be effectively controlled.

Abstract:
A backlight unit and a display device having the same are provided. A backlight unit includes at least one light source, at least one reflector disposed to enclose the at least one light source, a reflective sheet arranged under the reflector and a diffusion sheet arranged over the reflector, wherein the at least one reflector has at least one of cross sections shaped like an ellipse and a parabola, and has a reflective layer formed on an inner side thereof.
Abstract:
A display device is disclosed. The display device includes a display panel, a frame positioned in the rear of the display panel, a substrate positioned between the frame and the display panel, extended in an up-down direction of the frame, and mounted on the frame, a light source mounted on the substrate, and a lens covering the light source and mounted on the substrate. The lens includes a first stopper protruding and extending from a lower surface of the lens, and a first leg extended from the first stopper toward a lower part of the lens. The substrate includes a hole into which the first leg is inserted.
Abstract:
An optical lens, a backlight unit including the optical lens, and a display device including the optical lens are disclosed. The optical lens includes a first surface forming an upper part, a second surface positioned opposite the first surface and forming a lower part, and a third surface connecting the first surface and the second surface. At least a portion of the second surface forms a bottom parallel to the first surface. At least a portion of the second surface is inclined from the bottom toward the third surface.
Abstract:
Provided are a backlight unit and a display apparatus including the same. An optical lens of an optical unit has a shape asymmetrical with respect to a plane that bisectionally divides a center of an optical package. A plurality of reflectors each of which has an embossed or engraved shape are disposed on a top surface of the reflection sheet.
