Flat fluorescent lamp and driving method thereof, and liquid crystal display device

摘要

A flat fluorescent lamp is provided. In the flat fluorescent lamp, a discharge gas and a fluorescent material are disposed inside a chamber; first and second electrodes covered by a dielectric layer are disposed at the bottom of the chamber; first protruding points are disposed on a first side of each electrode; and second protruding points are disposed on a second side of each electrode. In each electrode, the first and the second protruding points are alternately laid. The first light-emitting region formed between the first protruding points and the first and second electrodes corresponding thereto and the second light-emitting region formed between the second protruding points and the first and second electrodes corresponding thereto are one of the entirely not overlapping and partially overlapping. Further, a driving method for the flat fluorescent lamp and a liquid crystal display device having the flat fluorescent lamp are provided.
