Abstract:
1. A boost converter of a liquid crystal display, wherein a transistor performing a switching operation in response to a switching pulse causes a reactor to be driven to generate a panel driving voltage, the boost converter comprising: an oscillator configured to generate an oscillation signal having a frequency, which varies in a predetermined pattern or randomly hops around a center frequency, in synchronization with a synchronizing signal, the oscillation signal also having the same frequency whenever each frame begins; a controller configured to output a switching signal for generating a required panel driving voltage through use of the oscillation signal output from the oscillator, a voltage detected as the panel driving voltage, and a preset reference voltage; and a driver configured to perform the switching operation on the transistor, which drives the reactor generating the panel driving voltage, through use of the switching signal output from the controller, wherein the oscillator comprises: wherein the counter section comprises:
