Display panel driver, method of driving display panel using the same and display apparatus having the same

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

• determining whether input image data represents a moving image or a static image;
• sensing a movement of a display apparatus or a user of the display apparatus;
• and
• performing a dithering operation to the input image data when:
• the input image data represents the moving image;
• or
• when the input image data represents the static image and the movement of the display apparatus or the user is sensed.

A display apparatus comprising:

• a display panel comprising a gate line and a data line;
• a controller comprising:
• a moving image determining part configured to determine whether an input image data represents a moving image or a static image,
• a sensing part configured to sense a movement of a display apparatus or a user of the display apparatus, and
• a dithering part configured to perform a dithering operation to the input image data when:
• the input image data represents the moving image, or
• the input image data represents the static image and the movement of the display apparatus or the user is sensed, the controller configured to generate a first control signal, a second control signal and a data signal;
• a gate driver configured to output a gate signal to drive the gate line based on the first control signal received from the controller;
• and
• a data driver configured to output a data voltage to drive the data line based on the second control signal and the data signal received from the controller.
