Display apparatus and a method of driving the same

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

• outputting a gate signal to a gate line of a display panel which displays an image;
• and
• outputting a data signal to a data line,
• wherein a transition time of the data signal is a time when the data signal transitions from a low level to a high level,
• the transition time of the data signal increases when a load of the display panel decreases, and
• when image data to be displayed on the display panel includes a toggle pattern and a direct current pattern, the transition time of the data signal applied to an area displaying the toggle pattern increases according to the decrease of the load of the display panel, and the transition time of the data signal applied to an area displaying the direct current pattern is maintained.

A display apparatus comprising:

• a display panel configured to display an image, and comprising a gate line and a data line;
• a gate driving part configured to output a gate signal to the gate line;
• a data driving part configured to output a data signal to the data line;
• and
• a timing controlling part,
• wherein the timing controlling part comprises:
• a pattern detecting part configured to receive first image data, detect patterns in the first image data, and output pattern detection data;
• a lookup table configured to store parameters corresponding to a plurality of display areas in the display panel;
• and
• a micro controlling part configured to receive the first image data, generate second image data and transition time control data using the first image data, the pattern detection data, and the lookup table, and output the second image data and the transition time control data to the data driving part, and
• wherein the transition time control data is used to control a transition time and a slew of the data signal.
