Liquid crystal display device, apparatus for driving the same, and method of driving the same

摘要

An LCD device includes an LCD panel, a source driving part, an operating part, a mean voltage generating part, and a pre-charging part. The LCD panel includes a switching element and a liquid crystal capacitor. The switching element is formed in a region defined by gate and source lines adjacent to each other. The liquid crystal capacitor is electrically connected to the switching element. The source driving part converts data signals into data voltages of analog type. The operating part determines a mean data signal of the data signals. The mean voltage generating part converts the mean data signal into a mean data voltage of analog type. The pre-charging part selectively applies the data voltages and the mean data voltage to the source lines, thereby improving an image display quality of the LCD device.
