  • Publication number: 20070247070
    Abstract: A flat fluorescent lamp which can be used with an LCD display includes a plurality of discharge channels. Pairs of electrodes are formed on both ends of the discharge channels. Each of the plurality of channels has an emitting section at the middle, and electrode sections on both ends thereof. A width of the electrode sections is the same as that of the emitting section. However, a height of the electrode sections is greater than a height of the emitting section, resulting in the electrode section having a cross-sectional area that is larger than that of the emitting section.

  • Patent number: 7084583
    Abstract: The present invention relates to an external electrode fluorescent lamp which can provide higher degree of and more improved uniformity of brightness than those of conventional ones, and to a LCD back light unit using the external electrode fluorescent lamp. The present invention also relates to an equipment and a driving device to adapt the LCD back light unit. The external electrode fluorescent lamp of the present invention is comprising: an upper panel of lamp which is serpentine shaped; a lower panel which is planar shaped and to be combined with the upper panel to make channels between the upper panel and the low panel; and external electrodes which are located at the two extreme sides at the surface of the upper panel.
