Abstract
A display device includes a display panel including a display area including sub-pixels, a data driver providing a data voltage to each of the sub-pixels through a data line, a gate driver providing a bias gate signal to each of the sub-pixels and a driving controller compensating for the data voltage written in a second area to which the bias gate signal having an activation level in a first period in which the data voltage is written in the first area is applied based on a first data voltage corresponding to a grayscale of a first area of the display area and a second data voltage corresponding to a grayscale of a different area from the first area of the display area.
Claims20
A display device comprising:
- a display panel including a display area including sub-pixels;
- a data driver providing a data voltage to each of the sub-pixels through a data line;
- a gate driver providing a bias gate signal to each of the sub-pixels;
- and
- a driving controller compensating for the data voltage written in a second area to which the bias gate signal having an activation level in a first period in which the data voltage is written in the first area is applied based on a first data voltage corresponding to a grayscale of a first area of the display area and a second data voltage corresponding to a grayscale of a different area of the first area of the display area.
A driving method of a display device, comprising:
- calculating a grayscale of a first area of a display area and a grayscale of a different area of the first area of the display area based on an input image data;
- determining a first data voltage based on the grayscale of the first area;
- determining a second data voltage based on the grayscale of the different area of the first area;
- and
- compensating for the data voltage written in a second area to which a bias gate signal having an activation level in a first period in which a data voltage is written in the first area is applied based on the first data voltage and the second data voltage.
