Abstract
A method of driving a display panel includes determining whether an input data signal represents a moving image or a static image, determining an image transition from a first static image to a second static image when the input data signal represents the static image, determining a number of afterimage compensation frames using data of the first static image and data of the second static image when the image transition occurs and inserting the afterimage compensation frames corresponding to a determined number of the afterimage compensation frames in a single low frequency driving cycle between a first normal frame corresponding to the first static image and a second normal frame corresponding to the second static image.
Claims20
A method of driving a display panel, the method comprising:
- determining whether an input data signal represents a moving image or a static image;
- determining an image transition from a first static image to a second static image when the input data signal represents the static image;
- determining a number of afterimage compensation frames using data of the first static image and data of the second static image when the image transition occurs;
- and
- inserting the afterimage compensation frames corresponding to a determined number of the afterimage compensation frames in a single low frequency driving cycle between a first normal frame corresponding to the first static image and a second normal frame corresponding to the second static image.
A display apparatus comprising:
- a display panel which displays an image;
- a driving controller which determines whether an input data signal represents a moving image or a static image, determines an image transition from a first static image to a second static image when the input data signal represents the static image, determines a number of afterimage compensation frames using data of the first static image and data of the second static image when the image transition occurs and inserts the afterimage compensation frames corresponding to a determined number of the afterimage compensation frames in a single low frequency driving cycle between a first normal frame corresponding to the first static image and a second normal frame corresponding to the second static image;
- and
- a data driver which generates a data voltage based on the data signal and outputs the data voltage to the display panel.
