In order that a boost converter of an LDI can reduce electromagnetic interference by generating a panel driving voltage through the use of a variable frequency, while achieving a stable boosting operation using the same frequency whenever each frame begins, an oscillator generates an oscillation signal having a frequency, which varies in a predetermined pattern or hops in a random pattern around a center frequency, and generates an oscillation signal having a preset fixed frequency whenever each frame begins.
