Problems solved by technology

A current transformer is placed at a first end of each CCFL so that electrical wires electrically connected to a second end of the CCFL opposite the first end must run away from the first end and be connected to the current transformers so as to induce an electromagnetic field such that The arrangement deteriorates the brightness uniformity of the backlight assembly and increases power consumption

Abstract

A backlight assembly includes at least one U-shaped lamp, a first connecting member, and a second connecting member. The U-shaped lamp includes a U-shaped lamp tube, a first external electrode covering a first end portion of the U-shaped lamp tube, and a second external electrode covering a second end portion of the U-shaped lamp tube. The U-shaped lamp tube generates light when a first driving voltage is applied to the first external electrode and a second driving voltage is applied to the second external electrode. The first connecting member is electrically connected to the first external electrode for applying the first driving voltage to the first external electrode. The second connecting member is electrically connected to the second external electrode for applying the second driving voltage to the second external electrode. Therefore, interference between a wire for applying power to the U-shaped lamp and the U-shaped lamp is reduced.

Description

technical field [0001] The invention relates to a backlight assembly and a display device with the backlight assembly. More particularly, the present invention relates to a backlight assembly capable of improving productivity and reducing power consumption, and a display device having the same. Background technique [0002] A liquid crystal display ("LCD") device includes an LCD panel for displaying images and a backlight assembly for providing light to the LCD panel. As the size of the LCD panel increases, the size of the backlight assembly also increases. Therefore, the LCD device uses a direct illumination type backlight assembly. [0003] A direct-illumination type backlight assembly includes a plurality of lamps. Generally, a direct lighting type backlight assembly uses a plurality of cold cathode fluorescent lamps ("CCFL"), and thus requires a plurality of inverters to drive the plurality of CCFLs electrically connected in parallel. Therefo...
