Patent ID: 8169390

Claim:
A liquid crystal display comprising: a liquid crystal panel assembly including a plurality of gate lines, a plurality of data lines crossing the gate lines, and a plurality of pixels electrically connected to the gate lines and the data lines; a signal controller receiving image data and a synchronization signal from an external graphics source, generating a control signal for driving the liquid crystal panel assembly, and converting format of the image data; a gate driver scanning the gate lines of the liquid crystal panel assembly by unit of horizontal scan period based on a gate voltage; a data driver selecting gray voltages corresponding to the image data from the signal controller for respective data lines on the liquid crystal panel assembly; an inverter generating a driving signal based on a base signal having a predetermined pulse duty ratio and an amplitude depending on a luminance distribution of the image data; and a lamp having on and off states and intensity controlled in response to the driving signal from the inverter.
