Abstract

In a backlight assembly capable of improving display quality and an LCD apparatus having the backlight assembly, the backlight assembly includes a lamp and an insulating member. The lamp includes a lamp tube and an electrode disposed on an end portion of the lamp tube. The insulating member is combined with the end portion of the lamp so as to surround the electrode and to prevent a heat generated from the electrode from being conducted toward the lamp tube. Therefore, a display quality of the LCD apparatus is improved.

Claims (35)

1. A backlight assembly comprising:

a lamp that includes a lamp tube and an external electrode disposed on an end portion of the lamp tube to surround an external surface of the lamp tube;

a lamp securing member securing the lamp, the lamp securing member including a securing clip electrically connected to the external electrode, wherein the securing clip combined with the end portion of the lamp tube secures the lamp; and

an insulating member combined with the end portion of the lamp to prevent a heat generated from the electrode from being conducted toward the lamp tube.

2. The backlight assembly of claim 1 , further comprising:

a receiving container including a receiving space that receives the lamp securing member, wherein the lamp securing member further comprises a base substrate and the securing clip is upwardly protruded from the base.

3. The backlight assembly of claim 2 , wherein the lamp comprises an electrode area and a light emitting area adjacent to the electrode area, a light is emitted through the light emitting area, and the electrode is disposed at the electrode area.

4. The backlight assembly of claim 3 , wherein the insulating member is extended in a direction perpendicular to a longitudinal direction of the lamp tube, and the insulating member is disposed between a clip region having the securing clip in the electrode area and the light emitting area.

5. The backlight assembly of claim 1 ,

wherein the insulating member comprises a hole that receives the end portion of the lamp, a recess that receives the end portion of the lamp or a groove that receives the end portion of the lamp.

6. The backlight assembly of claim 2 ,

wherein the insulating member covers a portion of the electrode, and the securing clip is disposed at a position corresponding to a remaining portion of the electrode.

7. A liquid crystal display (LCD) apparatus comprising:

an LCD panel displaying an image;

a backlight assembly including a lamp having a lamp tube and an external electrode disposed on an end portion of the lamp tube to surround an external surface of the lamp tube, a lamp securing member having a securing clip combined with the end portion of the lamp tube to secure the lamp and electrically connected to the external electrode and an insulating member combined with the end portion of the lamp so as to surround the electrode; and

a first receiving container receiving the backlight assembly and making contact with the insulating member so as to conduct the heat generated from the electrode to an exterior to the LCD apparatus.

8. The LCD apparatus of claim 7 , wherein the first receiving container comprises a metal.

9. The backlight assembly of claim 7 , further comprising:

a second receiving container including a receiving space that receives the lamp securing plate, wherein the lamp securing member further comprises a base and the securing clip is protruded from the base.

10. The LCD apparatus of claim 9 , wherein the lamp comprises an electrode area having the electrode and a light emitting area adjacent to the electrode area so as to generate a light, and the electrode area includes a clip region having the securing clip, a first region adjacent to the clip region and a second region adjacent to the clip region.

11. The LCD apparatus of claim 10 , wherein the insulating member comprises a first rod disposed in the first region, a second rod disposed in the second region and a connecting part connecting an end portion of the first rod to an end portion of the second rod.

12. The LCD apparatus of claim 11 ,

wherein the first and second rods comprise holes receiving the end portion of the lamp, recesses receiving the end portion of the lamp or grooves receiving the end portion of the lamp.

13. The LCD apparatus of claim 11 ,

wherein the connector is integrally formed with the first and second rods.

14. The LCD apparatus of claim 10 ,

wherein the first region is disposed between the clip region and the light emitting area, and the insulating member is extended in a direction perpendicular to a longitudinal direction of the lamp tube so as to be disposed in the first region.

15. The LCD apparatus of claim 7 ,

wherein the backlight assembly further comprises a plurality of the lamps parallelly arranged with one another.

16. The LCD apparatus of claim 15 ,

wherein the backlight assembly further comprises a plurality of the insulating members, and each of the insulating members is combined with one of the lamps.

17. The LCD apparatus of claim 15 ,

wherein the backlight assembly further comprises a plurality of the insulating members, and each of the insulating members is confined with the plurality of the lamps.

18. The backlight assembly of claim 9 ,

wherein the insulating member covers a portion of the electrode, and the securing clip is disposed at a position corresponding to a remaining portion of the electrode.
