Classification: CPC G | IPC G

Claim 10:
11. The display apparatus of claim 3, wherein the plurality of pixels are implemented as liquid crystal cells selectively implementing a first polarity and a second polarity,
wherein the timing controller further generates a vertical polarity control signal for controlling polarities of the liquid crystal cells,
wherein the timing controller compares (N−1)th (N being a natural number) line image data with Nth line image data by data output channel units, generates first clock edge information and the vertical polarity control signal as the current control information under a first condition where a data transition degree is greater than a threshold value as a result of the comparison, and generates second clock edge information and the vertical polarity control signal as the current control information under a second condition where the data transition degree is less than or equal to the threshold value as a result of the comparison, and
the first additional switch and the second additional switch are selectively turned on based on the first clock edge information and the vertical polarity control signal, and all of the first additional switch and the second additional switch are turned off based on the second clock edge information regardless of the vertical polarity control signal.
