Abstract

The present invention is broadly directed towards a receiving container for an LCD apparatus for securing a lamp and lamp wiring connected to a lamp. The receiving container has features for substantially preventing the lamp wiring from being disconnected from the lamp. For example, a first through-hole for receiving the lamp wiring, a first trench, securing members, and securing projections are utilized to substantially prevent lamp wiring from being disconnected from a lamp. Additionally, the LCD apparatus is easily handled, dissipates heat effectively, and has a light weight.

Claims

1. A backlight assembly comprising;

a light guide plate,

a light source assembly adjacent to the light guide plate and having a light source and a wire supplying power to the light source,

an inner frame having a lower plate and a sidewall, and receiving the light guide plate and the light source assembly, and

an outer frame positioned on an outside surface of the lower plate of the inner frame which is open to an outer atmosphere,

wherein the outer frame has a through-hole through which the wire passes when the wire extends from an inner space of the inner frame to an outer space of the inner frame.

2. The backlight assembly of claim 1, wherein the wire is extended through the sidewall of the inner frame.

3. The backlight assembly of claim 1, wherein the wire is held in a trench formed on the outer frame behind the through-hole.

4. The backlight assembly of claim 3, wherein the wire supplies the power to the light source from a power source.

5. The backlight assembly of claim 1, wherein a first portion of the outer frame is partially disposed on an inside surface of the lower plate of the inner frame, and a second portion of the outer frame is partially disposed on an outside surface of the lower plate of the inner frame.

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

an LCD panel displaying an image, and

a backlight assembly disposed under the LCD panel and providing light to the LCD panel, the backlight assembly comprising;

a light guide plate,

a light source assembly adjacent to the light guide plate and having a light source and a wire supplying power to the light source,

an inner frame having a lower plate and a sidewall, and receiving the light guide plate and the light source assembly, and

an outer frame positioned on an outside surface of the lower plate of the inner frame which is open to an outer atmosphere,

wherein the outer frame has a through-hole through which the wire passes when the wire extends from an inner space of the inner frame to an outer space of the inner frame.

7. The LCD apparatus of claim 6, wherein the wire is extended through the sidewall of the inner frame.

8. The LCD apparatus of claim 6, wherein the wire is held in a trench formed on the outer frame behind the through-hole.

9. The LCD apparatus of claim 8, wherein the wire supplies the power to the light source from a power source.

10. The LCD apparatus of claim 6, wherein a first portion of the outer frame is partially disposed on an inside surface of the lower plate of the inner frame, and a second portion of the outer frame is partially disposed on an outside surface of the lower plate of the inner frame.
