Display device and method of driving the same

A method of driving a display device having a plurality of pixels including a target pixel and adjacent pixels disposed in proximity to the target pixel, the method comprising:

• generating first compensated grayscale values by remapping respective input grayscale values from a first grayscale range to a second grayscale range;
• generating second compensated grayscale values by compensating for remapped grayscale values based on remapped grayscale values of the adjacent pixels, such that, in response to one of the adjacent grayscale values being increased, the second compensated grayscale value of the target pixel is decreased;
• generating data signals based on the second compensated grayscale values;
• and
• emitting, by at least one of the adjacent pixels, light having a color different from that of the target pixel.

A method having a plurality of pixels including a target pixel and adjacent pixels disposed in proximity to the target pixel, the method comprising:

• generating first compensated grayscale values by remapping respective input grayscale values from a first grayscale range to a second grayscale range, the remapping comprising:
• determining a global gain for the target pixel based on a first compensated grayscale value of the target pixel;
• and
• calculating a second compensated grayscale value of the target pixel based on the global gain and the first compensated grayscale values of the adjacent grayscale;
• generating second compensated grayscale values by compensating for remapped grayscale values based on remapped grayscale values of the adjacent pixels;
• generating data signals based on the second compensated grayscale values;
• and
• emitting, by at least one of the adjacent pixels, light having a color different from that of the target pixel.

A display device, comprising:

• a display unit including having a plurality of pixels including a target pixel and adjacent pixels disposed in proximity to the target pixel;
• a data converter to:
• receive grayscale values respectively corresponding to the plurality of pixels;
• remap the grayscale values of a first grayscale range to first compensated grayscale values of a second grayscale range;
• generate second compensated grayscale values by compensating for the grayscale values based on first compensated grayscale values of the adjacent pixels;
• calculate a difference value by subtracting a grayscale value of the target pixel from a first compensated grayscale value of the target pixel;
• calculate a first compensation value for the target pixel based on the first compensated grayscale values of the adjacent pixels;
• calculate a second compensation value by subtracting the first compensation value from an absolute value of the difference value;
• calculate a second compensated grayscale value of the target pixel based on the grayscale value and the second compensation value, and
• a data driver to generate data signals based on the second compensated grayscale values and provide the data signals to the plurality of pixels,
• wherein at least one of the adjacent pixels is configured to emit light in a color different from that of the target pixel, and
• wherein the data converter is configured to increase the first compensation value as one of the first compensated grayscale values of the adjacent pixels is increased.
