Abstract:
1. A liquid crystal display (LCD) comprising: a liquid crystal panel including a plurality of pixels and a plurality of boost lines connected to the plurality of pixels, the boost lines having an initial boost voltage applied thereto to place a voltage on each of the boost lines; a data driver applying a data voltage to a plurality of data lines connected to the plurality of pixels; a scan driver applying a scan voltage to a plurality of scan lines connected to the plurality of pixels in synchronization with a scan clock signal controlling an output of the scan signal for the data voltage to be applied to the plurality of pixels; and a boost driver applying the initial boost voltage to the plurality of boost lines connected to the plurality of pixels, the boost driver then applying a primary boost voltage to the plurality of boost lines to increase or decrease the voltage on the boost lines and then applying a secondary boost voltage to the plurality of boost lines to further increase or further decrease the voltage on the boost lines, the primary boost voltage and the secondary boost voltage being generated in synchronization with a boost clock signal controlling the output of the boost voltages, wherein the boost clock signal has different synchronization from the scan clock signal controlling the output of the scan signal.
