Disclosed herein are a backlight unit and a display device. The backlight unit includes a bottom cover, a light emitting device module disposed at the lower portion of the inside of the bottom cover, a light guide plate disposed adjacent to the light emitting device module and disposed in front of the bottom cover, at least one optical sheet and a reflective sheet disposed adjacent to the light guide plate, recesses, each of which is disposed with one opened side, disposed at the edges of at least one of the light guide plate, the reflective sheet and the at least one optical sheet, and protrusions disposed at one side of the bottom cover disposed with the light emitting device module so as to be inserted into the recesses of the at least one of the light guide plate, the reflective sheet and the at least one optical sheet.

Light emitting device comprising a plurality of fixing members disposed at different sides of a bottom cover

A backlight unit capable of emitting heat smoothly and a display device including the same are disclosed. The backlight unit includes a bottom cover, a light emitting module arranged in a predetermined area of the bottom cover, a reflective sheet provided on the bottom cover, the reflective sheet spaced apart a predetermined distance from the bottom cover, a plurality of first heat radiating members provided between the reflective sheet and the bottom cover, the plurality of the first heat radiating members spaced apart a predetermined distance from each other, a second heat radiating member arranged between the light emitting module and the first heat radiating members, and a projected part located in the second heat radiating member below the reflective sheet, the projected part supporting the reflective sheet to locate the reflective sheet spaced apart a predetermined distance from the first heat radiating members.

Backlight unit and display device including the same

A backlight unit capable of emitting heat smoothly and a display device including the same are disclosed. The backlight unit includes a bottom cover; a light emitting module arranged in the bottom cover; a first heat sink arranged to an outside of the bottom cover; and a second heat sink arranged in the bottom cover, the second heat sink located between the light emitting module and the first heat sink.

A backlight unit includes a bottom cover, a first heat sink portion disposed on the bottom cover, a second heat sink portion extended upward with respect to the first heat sink portion, and at least a portion of a light emission module placed in at least one recess or at least one hole of the first heat sink portion, and the light emission module disposed on the second heat sink portion.

Backlight unit and display device therewith

A lift device of a laser disc player reliably maintaining a predetermined gap between an objective lens of a pick-up unit and a disc. This lift device drives its lift mechanism by rotating a plurality of cam gears using the rotational force of the existing loading motor of the disc player without addition of drive means. The lift device comprises a spindle motor mounted on a bottom center of a chassis and rotating a disc, a turntable rotatably mounted on a frame and seating the disc thereon, a pick-up unit provided with an objective lens, a rack for moving the pick-up unit in a radial direction of the disc, a loading motor generating a rotational force used for driving a plurality of cam gears, and a lift mechanism for maintaining a predetermined gap between the objective lens of the pick-up unit and the disc.
