Patent ID: 11398202

Abstract:
Display apparatuses, data drivers and display controller are provided. The data drivers receive video signals, generate positive-polarity and negative-polarity gradation data signals with respect to a predetermined reference voltage based on the video signals, output the positive-polarity gradation data signals to one of a first and a second data line groups, and output the negative-polarity gradation data signals to the other data line group. The data drivers generate, as the positive-polarity gradation data signals, signals in which data pulses each having a positive-polarity analog voltage value corresponding to a luminance level of each pixel based on the video signal appear in predetermined cycles, and generate, as the negative-polarity gradation data signals, signals where data pulses each having a negative-polarity analog voltage value corresponding to a luminance level of each pixel appear in each predetermined cycle with phases different from the positive-polarity gradation data signals.
