Driving controller, display apparatus including the same and method of driving display panel using the same

A display apparatus comprising:

• a display panel which displays an image based on input image data;
• a gate driver which outputs a gate signal to the display panel;
• a driving controller which analyzes input image data to determine a peak luminance, set a boundary grayscale value and a minimum grayscale value based on a gamma value and the peak luminance, temporally and spatially arranges first data having the boundary grayscale value and second data having the minimum grayscale value to generate a data signal, drives the display panel for a low grayscale range in a digital driving method and drives the display panel for a normal grayscale range of which a grayscale is greater than the boundary grayscale value in an analog driving method, wherein the boundary grayscale value is a grayscale value of a boundary between the normal grayscale range and the normal grayscale range;
• and
• a data driver which generates a data voltage based on the data signal and outputs the data voltage to the display panel.

A method of driving a display panel, the method comprising:

• analyzing input image data to determine a peak luminance;
• setting a boundary grayscale value and a minimum grayscale value based on a gamma value and the peak luminance;
• and
• temporally and spatially arranging first data having the boundary grayscale value and second data having the minimum grayscale value to generate a data signal.
