Abstract:
1. A method of driving a liquid crystal display, comprising: transmitting a plurality of first enabling pulses to respective scan lines of a first group of scan lines in a first period of a predetermined time, wherein the predetermined time is a frame time or a sub-frame time; transmitting a plurality of second enabling pulses to respective scan lines of a second group of scan lines in a second period of the predetermined time; transmitting a common voltage signal to a common line, wherein polarities of pixel voltages of pixel units connected to the scan lines of the first group and of the second group are different, wherein a voltage of the common voltage signal is maintained at a first constant level during the first period, and the voltage of the common voltage signal is maintained at a second constant level during the second period, the first constant level being different from the second constant level, the common voltage signal transiting from the first constant level to the second constant level in an inversion period between the first period and the second period; and transmitting at least one dummy enabling pulse to only at least one dummy scan line during the inversion period of the common voltage signal, without transmitting the dummy enabling pulse to the first group of scan lines and the second group of scan lines, wherein in the inversion period the voltage of the common voltage signal is linearly changed from the first constant level to the second constant level.
