Problems solved by technology

When the length of the CCFL is longer, the voltage for driving the CCFL, the heat emitted from the CCFL, and the power consumption in the CCFL increase
Also, since the weight of the CCFL increases with its length, the CCFL may bend, thereby deteriorating the display quality of the LCD device

Abstract

Disclosed is a backlight assembly and an LCD apparatus having uniform brightness and low power consumption. The backlight assembly has a plurality of lamps for providing light to the LCD panel. Each of the plurality of lamps has two or more sub-lamps connected to each other in series. The backlight assembly has a brightness control unit disposed between the sub-lamps to reduce a brightness difference.

Description

Technical field [0001] The present invention relates to a backlight assembly and an LCD (liquid crystal display) device, in particular to a backlight assembly and LCD device with uniform brightness and low power consumption. Background technique [0002] The LCD device uses electrical signals generated by a device that processes image information to display images. In order to display images, the LCD device is generally provided with a liquid crystal control device and a light source device. The liquid crystal control device controls the liquid crystal according to the electrical signal from the image information processing device, and the light source device provides light to the liquid crystal control device. [0003] The light source device may be a one-dimensional light source for generating one-dimensional light, such as point light or linear light, or a two-dimensional light source, for generating two-dimensional light, such as surface light. The LCD device utilizes a one-d...
