Abstract: A stain compensating apparatus includes a camera, an input signal processing part, an edge compensating part and a stain compensating value generating part. The camera captures a display image from the display panel. The input signal processing part generates a luminance profile based on the display image captured by the camera. The edge compensating part compensates the luminance profile of a curved portion of the display panel. The stain compensating value generating part generates a stain compensating value for a pixel of the display panel using the compensated luminance profile.

Abstract: An optical compensation method for a display device including a pixel is provided. The method includes: providing test data having a first grayscale value to the display device; measuring a luminance of the pixel which emits light based on the test data; and calculating a compensation grayscale value based on a second target luminance and the measured luminance of the pixel. The second target luminance is lower than a first target luminance which is set based on the first grayscale value.

Abstract: A luminance correction system includes: a display device that displays an image of a first grayscale value; an image capturing device that generates a first image and a second image by capturing the displayed image; and an image separator that generates a first high-frequency image by extracting a high-frequency image from the first image, and generates a second low-frequency image by extracting a low-frequency image from the second image, wherein the display device includes: an image corrector that generates a corrected image data by analyzing the first high-frequency image and the second low-frequency image to provide an analyzation result and by correcting an image data with respect to the displayed image in accordance with the analyzation result to generate the corrected image data; and a display unit including a plurality of pixels that emit light with luminance corresponding to the corrected image data.
