Abstract: A display device includes: a visual sensor for generating visual sensing data by sensing an eye of a user; a display panel including a display area and pixels disposed on the display area; an image converter for generating a second image signal by converting a first image signal of the pixels based on the visual sensing data; and a data driver for providing the pixels with data signals corresponding to the second image signal. The image converter generates visual information based on the visual sensing data, determines a first area and a second area different from the first area of the display area based on the visual information, and generates the second image signal by converting grayscales of the second area in the first image signal.

Abstract: A stain compensation method using a screen calibration system includes generating first parameter data including first data blocks, each defined by at least one emission area, by photographing a display surface, generating second parameter data including second data blocks, the second data blocks being generated by merging first data blocks that are adjacent to each other in one direction and have an identical average grayscale value, and storing the second parameter data in a memory.
