摘要:
In a method for driving a common inversion type liquid crystal display apparatus including a plurality of signal lines, a plurality of scan lines, a common electrode, and a plurality of pixel units, a common voltage applied to the common electrode is inverted for every scan line. Also, digital video signals each including a plurality of digital color signals are time-divisionally received while one of the scan lines is selected. Further, a sequence of the digital video signals including the digital color signals is changed for every two consecutive frames to time-divisionally generate an output sequence of analog video signals including analog color signals, so that each of the analog color signals is placed exclusively at predetermined time slots of the output sequence. Additionally, the output sequence of the analog video signals including the analog color signals are time-divisionally supplied to the signal lines so that the analog color signals are supplied to their corresponding signal lines.
