Patent ID: 7561149

Claim:
A liquid crystal display (LCD) comprising: an LCD drive controller for outputting normal data, adjust data and control signals for controlling display of an image by the LCD according to the normal and adjust data, the control signals including a first scan signal and a second scan signal; and a liquid crystal display panel including a storage capacitor to be charged by the normal data according to application of the first scan signal, and to be charged by the adjust data according to application of the second scan signal, wherein the normal data represents image data received by the LCD drive controller and the adjust data represents offset data to offset the charge to the storage capacitor by the normal data, wherein the LCD drive controller sequentially supplies the first scan signal to each of n gate lines aligned on the liquid crystal display panel for a 1 H period, and sequentially supplies the second scan signal to the first gate line when the first scan signal is applied to the n/k (k is an integer of two or more) gate lines for switch-on.
