Abstract: A display panel driving apparatus includes a control circuit, a data driver and a gate driver. The control circuit is configured to receive a first control signal for recovering a clock signal from a display signal including image data and the clock signal, and calculate a root mean square of the first control signal to output a second control signal. The data driver is configured to receive the display signal, receive the second control signal, recover the clock signal from the display signal according to the second control signal, and output a data signal based on the image data to a data line of a display panel. The gate driving part is configured to output a gate signal to a gate line of the display panel.

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.
