A method of compensating for color deflection of a display device, the method comprising:
- dividing a display region of a display panel into a plurality of partial regions;
- displaying a reference image in the display region;
- measuring optical characteristics of the partial regions based on the reference image;
- calculating a region compensation factor by the partial regions based on the optical characteristics;
- and
- storing the region compensation factor in a storage device of the display device,
- wherein the display device comprises:
- the display panel;
- and
- an image data compensator to load the region compensation factor, to calculate a pixel compensation factor by interpolating the region compensation factor according to a resolution of the display panel, to calculate a compensation rate regarding each grayscale of pixel data, and to compensate for a grayscale of the pixel data based on the pixel compensation factor and the compensation rate regarding each grayscale.
A method of compensating for color deflection of a display device, the method comprising:
- loading a region compensation factor corresponding to a plurality of partial regions of a display panel;
- processing the loaded region compensation factor to calculate a pixel compensation factor corresponding to each pixel of the display panel by interpolating the region compensation factor according to a resolution of the display panel;
- receiving image data comprising pixel data;
- calculating a compensation rate regarding each grayscale of the pixel data;
- and
- compensating for the grayscale of each pixel data based on the pixel compensation factor and the compensation rate.
A display device comprising:
- a display panel comprising a plurality of partial regions;
- and
- an image data compensator for compensating for a grayscale of a plurality of pixel data of input image data based on a region compensation factor corresponding to the partial regions, and for outputting the compensated image data to the display panel,
- wherein the image data compensator comprises:
- a compensation factor storage device for storing the region compensation factor;
- a compensation factor converter for loading the region compensation factor, and for interpolating the region compensation factor according to a resolution of the display panel to calculate a pixel compensation factor;
- a grayscale compensation rate determiner configured to calculate a compensation rate regarding each grayscale of pixel data;
- and
- a data converter for compensating for a grayscale of the pixel data based on the pixel compensation factor and the compensation rate regarding each grayscale.
