发明名称 APPARATUS AND METHOD FOR DRIVING LAMP OF LIQUID CRYSTAL DISPLAY DEVICE
摘要 An apparatus and a method for driving a lamp of an LCD(Liquid Crystal Display) are provided to add a burst duty period to a lamp driving pulse period in an initial driving state of a backlight lamp to discharge the lamp easily, stabilize luminance, and prevent generation of initial inrush current. An apparatus for driving a lamp(24) of an LCD includes an MCU(Micro Processor Unit)(21), a transformer driver(22), and a transformer(23). The MCU controls the operation of the transformer driver such that a burst duty period in which a continuous driving pulse period and a period outputting no driving pulse alternate is included in a lamp driving pulse signal when a backlight lamp is initially driven. The transformer driver transforms an external DC voltage into an AC voltage under the control of the MCU. The transformer transforms the AC voltage supplied from the transformer driver into a high AC voltage and generates the lamp driving pulse signal including the burst duty period.
