Abstract

An external electrode fluorescent lamp for a backlight, including: a lamp that emits light; a first external electrode at one end of the lamp, and a second external electrode at a second end of the lamp; a dividing electrode between the first and second external electrodes and defining a plurality of divided regions; and a separating wall inside the lamp corresponding to the dividing electrode and separating the lamp into the divided regions.

Description

technical field [0001] The present invention relates to a backlight lamp, more specifically, to an external electrode fluorescent lamp suitable for the backlight of a large-area liquid crystal display device. Background technique [0002] With the recent development of portable electronic devices such as mobile phones, personal digital assistants (PDAs), and notebook computers, there is an increasing demand for light, thin, and small flat panel display devices used in portable electronic devices. Active research has been conducted on flat panel display devices, including liquid crystal display (LCD) devices, plasma display panel (PDP) devices, field emission display (FED) devices, and vacuum fluorescent display (VFD) devices. Among these various devices, LCD devices have been actively developed due to simple mass production techniques, convenient driving methods, and high image quality. [0003] Such LCD devices are transmissive display devices that use the refractive aniso...
