Abstract
An external electrode lamp capable of preventing a lighting defect by easily emitting secondary electron within a lamp tube, a method of manufacturing the external electrode lamp, and a liquid crystal display apparatus using the external electrode lamp. The external electrode lamp includes a lamp tube filled with a discharge gas, an external electrode encompassing both ends of the lamp tube, and a conductive material disposed at an inner surface of the both ends of the lamp tube.
Claims20
An external electrode lamp, comprising:
- a lamp tube filled with a discharge gas;
- an external electrode encompassing at least one end of the lamp tube;
- and
- a conductive material disposed at an inner surface of at least one end of the lamp tube.
A method of manufacturing an external electrode lamp, the method comprising:
- providing a lamp tube of which both ends are opened;
- coating an inner surface of an emission region of the lamp tube with a fluorescent material;
- forming a conductive material at an inner surface of at least one end of the lamp tube;
- filling the lamp tube with a discharge gas and sealing the both ends of the lamp tube;
- and
- forming an external electrode encompassing at least one end of the lamp tube.
A liquid crystal display apparatus, comprising:
- a lamp assembly including a plurality of external electrode lamps in which a conductive material is formed at an inner surface of at least one end of the lamp tube, at least one end of the lamp encompassed by an external electrode, and a circuit board connecting the plurality of external electrode lamps in parallel;
- a bottom chassis receiving the lamp assembly therein;
- a liquid crystal display panel arranged over the lamp assembly;
- a plurality of optical sheets disposed between the liquid crystal display panel and the lamp assembly;
- and
- a top chassis encompassing a peripheral part of the liquid crystal display panel and being locked with the bottom chassis.
