    Abstract: A display panel driving apparatus is disclosed. In one aspect the apparatus includes a gate driving part and a data driving part. The gate driving part is configured to increase a gate signal applied to a gate line of a display panel from an OFF voltage to a ON voltage, in response to an activation of a gate clock signal. It is also configured to decrease the gate signal from the ON voltage to a kickback compensation voltage between the OFF voltage and the ON voltage through a plurality of steps in response to an activation of a kickback compensation signal. The data driving part is configured to apply a data signal to a data line of the display panel. Therefore, a data-charging rate may be increased, and thus a display quality of the display apparatus may be increased.

    Abstract: A display apparatus includes a display panel, a memory, a bit-data convertor, a switch, and a gate driver. The display panel includes pixels. Each pixel is connected to one of the data lines and one of the gate lines. The memory stores a plurality of image data corresponding to a frame period. The bit-data convertor determines a plurality of bit data. Each of the bit data corresponds to a degree of change between adjacent image data among the plurality of image data, obtains a sum of the bit data, and outputs the sum of the bit data as a total count bit data value. The switch outputs a first pulse control signal corresponding to the total count bit data value. The gate driver generates a gate signal based on the first pulse control signal, and to output the gate signal to one of the gate lines.
