Problems solved by technology

However, since the current flowing through the discharge space is concentrated in the discharge space formed by the compensation electrode, there will be pinhole defects that can partially break through the lamp body

Embodiment Construction

[0025] Hereinafter, the present invention will be explained in detail with reference to the accompanying drawings.

[0026] figure 1 A perspective view showing a flat fluorescent lamp according to an exemplary embodiment of the present invention. figure 2 express figure 1 Plan view of a flat fluorescent lamp.

[0027] refer to figure 1 and 2 , the flat fluorescent lamp 100 includes a lamp body 200 , an external electrode 300 and an auxiliary electrode 400 .

[0028] The lamp body 200 is divided into a plurality of discharge spaces 230 that emit light. In order to emit planar light, the lamp body 200 is substantially rectangular in plan view. The lamp body 200 performs plasma discharge in the discharge space 230 in response to the discharge voltage of the inverter. The lamp body 200 converts ultraviolet light generated in the plasma discharge into visible light and emits the visible light. The lamp body 200 is provided with an inner space divided into discharge spaces ...

Abstract

A flat fluorescent lamp includes a lamp body having a plurality of discharge spaces, an external electrode that is formed at both ends of the lamp body and intersects the discharge spaces, and an auxiliary electrode coupled to the lamp body and electrically connected to the external electrode. The external electrode includes a main electrode portion intersecting the discharge spaces and a first compensation electrode portion extending from the main electrode portion such that the first compensation electrode portion is formed at the outermost discharge spaces of the discharge spaces. The auxiliary electrode is formed at the outermost discharge spaces where the first compensation electrode portion is formed. Thus, a pin-hole defect of the flat fluorescent lamp may be prevented.

Description

technical field [0001] The invention relates to a flat fluorescent lamp, a backlight assembly and a liquid crystal display device. More particularly, the present invention relates to a flat fluorescent lamp capable of preventing pinhole defects, a backlight assembly, and a liquid crystal display device having the flat fluorescent lamp. Background technique [0002] In general, liquid crystal display devices display images using the optical and electrical properties of liquid crystals, such as their anisotropic refractive index and anisotropic dielectric constant. Such a liquid crystal display device exhibits light weight, low power consumption, and low driving voltage compared with display devices of a cathode ray tube or a plasma display panel. [0003] Liquid crystal display devices require a backlight assembly because the display panel itself is not emissive. [0004] Tubular cold cathode fluorescent lamps are generally used as light sources for liquid crystal display d...
