An apparatus for driving a lamp of a liquid crystal display device includes a control signal generator generating a switching control signal, a waveform modulator modulating at least an amplitude of the switching control signal to generate a modulated switching control signal, and an AC waveform generator converting a supply voltage based on the modulated switching control signal to generate an AC waveform for driving the lamp, the AC waveform including at least two different peak-to-peak amplitudes within a time period.

Apparatus and method for driving lamp of liquid crystal display device

A ferroelectric liquid crystal display and a fabricating method thereof that is capable of improving light efficiency by preventing light efficiency deterioration due to the low voltage holding ratio of a ferroelectric liquid crystal. The ferroelectric liquid crystal display supplies red, green and blue data signals to each of the liquid crystal cells and is in a stand-by state during a responding period of liquid crystal, and then sequentially generates red, green and blue lights corresponding to each of the red, green and blue data signals. With this configuration, deterioration in brightness due to the low voltage holding ratio of the ferroelectric liquid crystal can be prevented and the light efficiency can be increased.
