Liquid crystal display apparatus and method of driving the same

摘要

Present embodiments may include a liquid crystal display apparatus, using a line reversal method, wherein at least one pulse is inserted between charging periods, and a method of driving the liquid crystal display apparatus. According to present embodiments, in a liquid crystal display apparatus employing a polarity reversal method, audible noise may be removed without increasing a frame frequency and reducing a charging time of a storage capacitor.

1. A method of driving a liquid crystal display apparatus, including a line reversal method and a plurality of pixels, the method comprising:
applying a data signal and a common voltage having a first voltage level to selected pixels of a first line in a first charging period, so that selected pixels of the first line have a first polarity; electrically blocking pixel electrodes of the plurality of pixels and data lines for delivering the data signal in a first intermediate period, wherein the common voltage includes at least one pulse; applying the data signal and the common voltage having a second voltage level lower than the first level to selected pixels of a second line in a second charging period, so that selected pixels of the second line have a second polarity, opposite the first polarity; and electrically blocking the pixel electrodes of the plurality of pixels and the data lines in a second intermediate period, wherein the common voltage includes at least one pulse, wherein one period includes the first charging period, the first intermediate period, the second charging period, and the second intermediate period in order, and wherein, in the first intermediate period, the common voltage has a third voltage level between the first voltage level and the second voltage level, and includes at least one pulse having a rising edge and a falling edge, and wherein, in the second intermediate period, the common voltage has a fourth voltage level lower than the second voltage level, and includes at least one pulse having a rising edge and a falling edge.
