Abstract

The present invention relates to method for driving lamps, driving circuit for performing the same and liquid crystal display device having the same. The lamp driving circuit includes a power-generating section, a distribution sensing section and a feedback control section. The power-generating section generates a lamp driving power to drive a plurality of lamps. The distribution sensing section divides the lamp driving power to the plurality of lamps. The distribution sensing section senses the lamp driving power to generate a feedback signal. The feedback control section checks whether or not the plurality of lamps is lit. The feedback control section blocks the feedback signal from being reflected in the lamp driving power before the plurality of lamps is lit.

Description

technical field

[0001] The present invention relates to a method of driving a lamp, a driving circuit applying the method, and a liquid crystal display device ("LCD") having the driving circuit. More particularly, the present invention relates to a lamp driving method capable of preventing lighting defects of the lamp, a driving circuit to which the driving method is applied, and a liquid crystal display device having the driving circuit. Background technique

[0002] In general, LCD devices have features such as light weight, low power consumption, and low driving power compared with other types of display devices, and thus LCD devices are mainly used in monitors, notebook computers, cellular phones, and the like. The LCD device has an LCD panel that displays images using light transmittance of liquid crystal molecules, and a backlight assembly located below the LCD panel to provide light thereto.

[0003] The backlight unit includes a lamp, such as a cold cathode fluoresc...
