Display device and driving method thereof

A display device comprising:

• a processor;
• and
• a display panel configured to receive observation grayscale values from the processor,
• wherein the display panel includes:
• a data driver configured to apply data voltages to data lines;
• a target pixel coupled to at least one of the data lines and configured to emit light of a first color;
• second color observation pixels each coupled to at least one of the data lines, and configured to emit light of a second color different from the first color;
• and
• third color observation pixels each coupled to at least one of the data lines, and configured to emit light of a third color different from the first color and the second color,
• wherein the target pixel is located in a first direction from a first one of the second color observation pixels, a second one of the second color observation pixels is located in the first direction from the target pixel, the target pixel is located in a second direction from a third one of the second color observation pixels, a fourth one of the second color observation pixels is located in the second direction from the target pixel, and no other pixels are located between the target pixel and each of the second color observation pixels,
• wherein the target pixel is located in a third direction from a first one of the third color observation pixels, a second one of the third color observation pixels is located in the third direction from the target pixel, the target pixel is located in a fourth direction from a third one of the third color observation pixels, a fourth one of the third color observation pixels is located in the fourth direction from the target pixel, and no other pixels are located between the target pixel and each of the third color observation pixels,
• wherein the display panel applies a first data voltage to the target pixel, when the observation grayscale values for the second and third color observation pixels exceed a reference value,
• wherein the display panel applies a second data voltage to the target pixel, when at least one of the observation grayscale values for the second and third color observation pixels does not exceed the reference value, and
• wherein the first data voltage and the second data voltage are different from each other.
