    摘要: A display apparatus includes a display panel including pixels, a gate driver to sequentially apply a gate signal to gate lines in response to a gate control signal, a first source driver to apply a first data voltage to data lines in response to a data control signal, and a second source driver disposed at an opposite side of the display panel from the first source driver with respect to the display panel. The second source driver is configured to apply a second data voltage to the data lines at every time period, at which the gate signal is applied to the gate lines, in response to the clock signal. The pixels display a gray scale in response to the first and second data voltages, and a time period of a rising edge of the clock signal is the same as a time period of a rising edge of the gate signal. In addition, the high level period of the clock signal is shorter than the high level period of the gate signal.

The timing controller is configured to receive a first subpixel data for the first subpixel and a second subpixel data for the second subpixel. When the second subpixel is determined to be defective, the timing controller generates a compensated grayscale of the second subpixel data. The data driver is configured to apply a precharge voltage to the second subpixel and a charging voltage to second subpixel through a data line, wherein the precharge voltage is based on a grayscale of the first subpixel data and the charging voltage is based on the compensated grayscale of the second subpixel data.
