1. A display apparatus comprising:
a display panel comprising a data line and a pixel connected to the data line, and configured to display an image based on an input image data;
a data driver configured to output a data voltage to the data line; and
a controller connected to the data driver and configured to control an operation of the data driver,
wherein the controller is further configured to:
determine a luminance difference according to a voltage drop of the data voltage or a voltage drop of a driving voltage of the display panel;
determine whether the input image data is a still image or a video image; and
determine a minimum driving frequency of the display panel using flicker values according to the luminance difference and an input grayscale value when the input image data is the still image.
