Abstract

A flat fluorescent lamp (FFL) for display devices, which has an improved electrode structure for plasma discharge, thus being efficiently operated using a low voltage and having high optical efficiency, is disclosed. The FFL of the present invention is provided with a plurality of branch electrodes extending from main electrodes, provided on opposite ends of a lamp body, in opposite directions toward the opposite main electrodes and being parallel to longitudinal axes of the discharge channels. Furthermore, the FFL may include joint electrodes which electrically couple the branch electrodes, provided around each of the opposite ends of the lamp body, to each other. The FFL may further include step electrodes and / or inductive electrodes.

Description

technical field

[0001] The present invention mainly relates to a flat fluorescent lamp used as a backlight part of a display device, and more particularly to a fluorescent lamp for a display device having an improved structure of plasma discharge electrodes so as to operate effectively even at a low voltage and to have high optical efficiency . Background technique

[0002] In general, display devices can be classified into two types according to their light-emitting capabilities: emissive display devices and non-emissive display devices. Liquid crystal displays (LCDs), which have been widely used as flat panel display devices in recent years, are representative of non-emissive display devices, and must be provided with backlight units (BLUs) because they cannot emit light by themselves.

[0003] In recent years, more and more manufacturers prefer to use flat fluorescent lamps (FFLs) as the backlight components of liquid crystal displays. According to the different configu...
