Embodiment Construction

[0043] The present invention will be described more fully hereinafter with reference to the accompanying drawings, in which embodiments of the invention are illustrated. In the drawings, the size and relative sizes of layers and regions may be exaggerated for clarity. It will be understood that when an element or layer is referred to as being "on," "connected to," or "coupled to" another element or layer, that element or layer may be Either directly on, or directly connected to or coupled to, the other element or layer, intervening elements or layers may also be present. In contrast, when an element is referred to as being "directly on" or "directly connected to" or "directly coupled to" another element or layer, there are no intervening elements or layers present.

Abstract

A backlight assembly and a method of assembling the backlight assembly that includes a plurality of lamps (210) having first (213) and second electrodes, a receiving container and a lamp ground member (300). The receiving container has a bottom plate over which the lamps are disposed, and a side wall extending from the bottom plate to form a receiving space. The lamp ground member includes a ground plate (310) grounded to the bottom plate, and a plurality of electrode ground portions (320) protruded from the ground plate and making contact with the first electrode thereby eliminating the need for a separate part for grounding the first electrode of the lamp and permitting easier assembly of the backlight assembly.

Description

technical field [0001] The present invention relates to a backlight assembly for a liquid crystal display (LCD), and more particularly, to a backlight assembly improved in manufacture using an automated assembly process. Background technique [0002] Generally, backlight assemblies for liquid crystal displays are classified as direct-lit or edge-lit. A direct-lit backlight assembly includes a light source positioned below a liquid crystal panel, while an edge-lit backlight assembly includes a light source disposed on one or both sides of a light guide plate positioned below the liquid crystal panel. The lighting uniformity and durability of the direct-lit backlight assembly are worse than those of the edge-lit type. The direct-lit backlight assembly has multiple parallel lamps to improve light efficiency, and thus is used in large-sized LCD devices. [0003] When driving these lamps from one end, the lamp driving voltage is applied to the hot electrode of the lamp and the ...
