Display apparatus and method of driving the same

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

• inputting image data including update image data and blank image data to a timing controller at a number of frames per second of a middle level, the middle level being lower than a high level of 60 frames-per-second (fps);
• operating a display panel in a film mode in which the display panel is operated at a frequency having the middle level when a number of the update image data of the image data input during a specific time period satisfies a film mode condition in which the number of the update image data is in a range of between F and G inclusive, where F is a natural number and G is a natural number greater than F;
• and
• controlling a first power control signal to a data driver that applies a data voltage to the display panel while in the film mode such that the first power control signal is in a first state during output periods of the film image data, the first power control signal is in a second state during blank periods between the output periods of the film image data, the data driver is to receive power during the first state of the first power control signal, and the data driver is not to receive power during the second state of the first power control signal.

A display apparatus, comprising:

• a display panel to display images;
• a timing controller to receive input image data at a number of frames per second of at least a middle level, the middle level being lower than 60 frames-per-second (fps) and to generate a gate control signal and a data control signal, the timing controller including an image converter to, when the received input image data is moving image data:
• be operated in a film mode;
• be operated in a normal mode;
• and
• output film image data at a number of frames per second of the middle level during the film mode;
• and
• a data driver to apply a data voltage corresponding to the film image data to the display panel based on the data control signal, wherein the data driver is to:
• invert a polarity of the data voltage whenever the data voltage corresponding to the frame image data in the film image data is output based on the first polarity signal during the film mode, and
• when two or more copy image data in one frame image data group among the frame image data groups, input when an absolute value of a cumulative polarity is equal to or greater than a predetermined value, are consecutive and cumulative polarity increases due to a polarity inversion when the data voltage corresponding to the first copy image data is output, the film image data includes copy image data right after the first copy image data.
