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 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.
