Display apparatus and a method of operating the same

A method of operating a display apparatus including a display panel, the method comprising:

• generating a mode selection signal and output image data in response to input image data, the mode selection signal identifying a first operation mode or a second operation mode;
• generating first through M-th data voltages and (M+1)-th through N-th data voltages in response to the mode selection signal and the output image data, where M is a natural number and N is a natural number greater than M;
• and
• applying the first through N-th data voltages to first through N-th data lines connected to the display panel, respectively,
• wherein, during a first duration of the first operation mode, each of a polarity pattern of the first through M-th data voltages and a polarity pattern of the (M+1)-th through N-th data voltages repeats a first polarity pattern,
• wherein, during a first duration of the second operation mode, the polarity pattern of the first through M-th data voltages repeats the first polarity pattern, and the polarity pattern of the (M+1)-th through N-th data voltages repeats a second polarity pattern different from the first polarity pattern.

A method of operating a display apparatus including a display panel, the method comprising:

• generating a first group of data voltages having a first polarity pattern in a first operation mode and a second group of data voltages having the first polarity pattern in the first operation mode;
• applying the first group of data voltages to a first group of data lines of the display panel and applying the second group of data voltages to a second group of data lines of the display panel;
• generating a third group of data voltages having the first polarity pattern in a second operation mode and a fourth group of data voltages having a second polarity pattern in the second operation mode, wherein the second polarity pattern is different from the first polarity pattern;
• and
• applying the third group of data voltages to first group of data lines of the display panel and applying the fourth group of data voltages to the second group of data lines of the display panel.
