Backlight unit of liquid crystal display
View Patent ↗A backlight unit of a liquid crystal display for arranging a wire for supplying a driving current connected to a common electrode to be penetrated a piece provided at the inside portion is disclosed. In the backlight unit of the liquid crystal display, a cover bottom includes an accepting space to which the reflection sheet is attached. A first and a second side bottoms are arranged within the accepting space of the cover bottom, and are located to be symmetrical with both sides of the reflection sheet. A first and second common electrodes are commonly connected to both side ends of the plurality of lamps. A first piece is located between the lamps, and is formed to penetrate the first side bottom and the cover bottom. And wherein, a first wire for supplying a driving current connected to the first common electrode is arranged to penetrate the first common electrode.
1. A backlight unit of a liquid crystal display, including a plurality of lamps irradiating a light to a liquid crystal display panel, and a reflection sheet reflecting a light irradiated from the lamps toward the liquid crystal display panel direction, comprising:
a cover bottom including an accepting space to which the reflection sheet is attached;
a first and a second side bottoms arranged side wall within the accepting space of the cover bottom, and located to be symmetrical with both sides of the reflection sheet;
a first and second common electrodes commonly connected to both side ends of the plurality of lamps;
a first piece located between the lamps, and formed to penetrate the first side bottom and the cover bottom; and
wherein a first wire for supplying a driving current connected to the first common electrode is arranged to penetrate the first piece,
wherein the first piece has a hole and is formed to penetrate toward a bottom of the cover bottom, and
wherein the first piece is located to be adjacent to the first common electrode.
2. The backlight unit of the liquid crystal display as claimed in claim 1 , further comprising:
a second piece located between the lamps and formed to penetrate the second side bottom and the cover bottom,
wherein the second piece has a hole and is formed to penetrate toward a bottom of the cover bottom,
wherein the second piece is located to be adjacent to the second common electrode, and
wherein a second wire for supplying a driving current connected to the second common electrode is arranged to penetrate the second piece.
3. The backlight unit of the liquid crystal display as claimed in claim 1 or claim 2 , wherein the first and second side bottoms are made of silicon.
4. The backlight unit of the liquid crystal display as claimed in claim 2 , wherein the first and second pieces are made of a plastic.
5. The backlight unit of the liquid crystal display as claimed in claim 2 , wherein the first and second pieces are formed at a location where is symmetrical to each other.
6. The backlight unit of the liquid crystal display as claimed in claim 2 , wherein The first and second pieces are formed at a location where is not symmetrical to each other.
7. The backlight unit of the liquid crystal display as claimed in claim 2 , wherein the diameters of the first and second pieces are the same each other.
8. The backlight unit of the liquid crystal display as claimed in claim 2 , wherein the diameters of the first and second pieces are different from each other.
