Abstract
A display device may include a display panel including pixels, and a display panel driver. The display panel driver may receive an input image, detect a first pattern from input image data of the input image, determine a luminance weight for each color based on a luminance of the input image of the first pattern and a luminance of a reference image of a second pattern, apply, in response to detecting of the first pattern, the luminance weight to data voltages to determine compensation data voltages, and apply the compensation data voltages to the pixels.
Claims20
A display device comprising:
- a display panel including pixels;
- and
- a display panel driver configured to:
- receive an input image,
- detect a first pattern from input image data of the input image,
- determine a luminance weight for each color based on a luminance of the input image of the first pattern and a luminance of a reference image of a second pattern,
- apply, in response to detecting of the first pattern, the luminance weight to data voltages to determine compensation data voltages, and
- apply the compensation data voltages to the pixels.
A display device comprising:
- a display panel including a plurality of pixels;
- and
- a display panel driver configured to:
- receive an input image,
- detect a first pattern from input image data of the input image,
- determine a luminance weight for each color based on a luminance of the input image and a luminance of a reference image having a second pattern,
- determine a grayscale weight for each color based on a color ratio of a current grayscale value of the input image and a color ratio of a reference grayscale value of the reference image,
- apply the grayscale weight to data voltages to determine a first compensation data voltages,
- apply, in response to detecting of the first pattern, the luminance weight to the first compensation data voltages to determine second compensation data voltages, and
- apply the second compensation data voltages to the pixels.
