发明名称 Method of driving liquid crystal panel, and liquid crystal display apparatus
摘要 A liquid crystal display apparatus drives an active-matrix liquid crystal panel by the use of the line reversal driving method. To do so, a common driver AC-drives one of a pair of electrode in each of all the pixels of the liquid crystal panel. An adding circuit obtains the sum of a plurality of gradation components for deciding the gradations of the pixels in one of the columns in the liquid crystal panel at intervals of the predetermined horizontal period. A voltage setting portion in a source driver corrects a reference voltage difference DeltaVref on the basis of the sum at intervals of the horizontal period, divides the corrected reference voltage difference DeltaVrefa, decides a plurality of gradation voltages, and selects voltages to be applied to a plurality of data lines in the liquid crystal panel from among the gradation voltages based on the plurality of gradation components. The selected plurality of voltages are applied to the plurality of data lines.
