Abstract
Provided are a backlight assembly and a display device having the same. The backlight assembly includes; a light guide plate (“LGP”) having a light incident portion upon which light is incident and an opposite portion which is disposed substantially opposite to the light incident portion, a lower housing which accommodates the LGP therein, and at least one LGP fixing tape which fixes the LGP into the lower housing, wherein the at least one LGP fixing tape is interposed between the lower housing and lower surfaces of two opposite ends of the light incident portion of the LGP.
Claims17
A backlight assembly comprising:
- a light guide plate comprising a light incident portion upon which light is incident and an opposite portion which is disposed substantially opposite the light incident portion;
- a lower housing which accommodates the light guide plate therein;
- light guide plate fixing tapes which fix the light guide plate into the lower housing;
- and
- a light source unit adjacent to the light incident portion of the light guide plate, the light source unit comprising a circuit board, and at least one light source element on the circuit board,
- wherein
- the light guide plate fixing tapes are interposed between the lower housing and lower surfaces of two opposite ends of the light incident portion of the light guide plate, and
- an entire of the light guide fixing tapes is outside the circuit board of the light source unit, in a plan view,
- wherein a lower surface of the light guide plate fixing tapes is only adhered directly to the lower housing, and an upper surface of the light guide plate fixing tapes is only adhered directly to the light guide plate.

A backlight assembly comprising:
- a light source unit comprising a circuit board, and at least one light source element mounted on the circuit board;
- a light guide plate fixing tape disposed at opposing ends of the light source unit;
- a light guide plate disposed adjacent to the at least one light source element on the circuit board, wherein the light guide plate guides light emitted from the at least one light source element;
- and
- a lower housing which accommodates the light source unit and the light guide plate therein,
- wherein
- the light guide plate fixing tape is disposed between the lower housing and the light guide plate, and fixes the light incident portion of the light guide plate in place;
- part of the light guide plate is adhered to at least part of the light guide plate fixing tape, and an entire of the light guide fixing tape is outside the circuit board of the light source unit, in a plan view, and
- a lower surface of the light guide plate fixing tapes is only adhered directly to the lower housing, and an upper surface of the light guide plate fixing tapes is only adhered directly to the light guide plate.
6 more elements
A display device comprising:
- a light guide plate having a light incident portion upon which light is incident and an opposite portion which is disposed substantially opposite to the light incident portion;
- a light source unit adjacent to the light incident portion of the light guide plate, the light source unit comprising a circuit board, and at least one light source element on the circuit board;
- a lower housing which accommodates the light guide plate therein;
- a backlight assembly having a light guide plate fixing tape which fixes the light guide plate into the lower housing;
- and
- a display panel which receives light from the backlight assembly,
- wherein
- the light guide plate fixing tape is interposed between the lower housing and lower surfaces of opposing ends of the light incident portion of the light guide plate, and
- an entire of the light guide fixing tape is outside the circuit board of the light source unit, in a plan view,
- wherein a lower surface of the light guide plate fixing tapes is only adhered directly to the lower housing, and an upper surface of the light guide plate fixing tapes is only adhered directly to the light guide plate.
