Light and liquid crystal display device having the same
A light for a liquid crystal device comprises a side supporter, a lamp fixing portion installed at a front surface of the side supporter, and a U-shaped lamp insertingly fixed into the lamp fixing portion.
1. A backlight for flat panel display device having an image display region, comprising:
a plurality of U-shaped lamps providing the light to the flat panel display device;
supporters disposed at the both end sides of the U-shaped lamps;
a plurality of lamp fixing portions at the supporter for fixing the U-shaped lamps, the lamp fixing portions having a through hole; and
a pad formed below the U-shaped lamps, the pad being formed in the strip shape, the pad being continuously extended along the substantial whole length of one side of the flat panel display device in parallel to the supporters through the holes of a plurality of lamps fixing portions so that a plurality of lamps are contacted with one pad to absorb the impact to the lamps,
wherein the lamp fixing portions protrude from the supporters so that the U-shaped lamps are disposed at the region adjacent to the image display region.
2. The backlight of claim 1 , wherein a width of each of the lamp fixing portion corresponding to a curved portion of the U-shaped lamps has a width of 4 to 5 mm.
3. The backlight of claim 1 , further comprising reflector installed below the U-shaped lamp.
4. The backlight of claim 1 , wherein a curved portion of the U-shaped lamp is inserted into the through hole.
5. The backlight of claim 1 , wherein the pad is formed of silicon.
6. The backlight of claim 1 , wherein only portion of the pad in contact with the U-shaped lamp is formed of silicon.
7. The backlight of claim 1 , wherein the lamp fixing portions have a semi-cylindrical shape, a triangular shape or a rectangular shape.
8. The backlight of claim 1 , wherein an upper edge of each of the supporters positioned at the U-shaped lamp sides is chamfered.
9. The backlight of claim 8 , wherein the upper edge of each of the supporters is chamfered with a certain angle of 10 to 80 degrees.
10. The backlight of claim 1 , further comprising an optical sheet installed over the U-shaped lamps.
11. The backlight of claim 1 , wherein the U-shaped lamps include a cold cathode fluorescence lamp (CCFL).
12. The backlight of claim 1 , wherein the supporters are formed at a non-luminescent region, and the lamp fixing portions are at a luminescent region.
13. A liquid crystal display (LCD) device, comprising:
a liquid crystal display panel having an image display region;
a plurality of U-shaped lamps providing the light to the liquid crystal display panel;
supporters below the liquid crystal display panel, the supporters being disposed at the both end sides of the U-shaped lamps;
a plurality of lamp fixing portions below the supporter for fixing the U-shaped lamps, the lamp fixing portions having a through hole; and
a pad formed below the U-shaped lamps, the pad being formed in the strip shape, the pad being continuously extended along the substantial whole length of one side of the flat panel display device in parallel to the supporters through the holes of a plurality of lamps fixing portions so that a plurality of lamps are contacted with one pad to absorb the impact to the lamps,
wherein the lamp fixing portions protrude from the supporters so that the U-shaped lamps are disposed at the region adjacent to the image display region.
14. The LCD device of claim 13 , wherein a width of each of the lamp fixing portion has an width of 4 to 5 mm.
15. The LCD device of claim 13 , further comprising a reflector installed below the U-shaped lamps.
16. The LCD device of claim 13 , wherein the pad is formed of silicon.
17. The LCD device of claim 13 , wherein only a portion of the pad in contact with the U-shaped lamps is formed of silicon.
18. The LCD device of claim 13 , further comprising an optical sheet installed over the U-shaped lamp.
19. The LCD device of claim 13 , wherein the lamp fixing portion has a semi-cylindrical shape, a triangular shape or a rectangular shape.
20. The LCD device of claim 13 , wherein an upper edge of the supporter positioned at the U-shaped lamp side is chamfered.
21. The LCD device of claim 20 , wherein the upper edge of each of the supporters is chamfered with a certain angle of 10 to 80 degree.
22. The LCD device of claim 13 , wherein each of the U-shaped lamp includes a cold cathode fluorescence lamp (CCFL).
