Abstract: Embodiments of the disclosure relate to an optical compensating system and method. Specifically, there may be provided an optical compensating method, comprising generating a first photographed image for a first area of a display panel including an overlapping area, generating a second photographed image for a second area of the display panel including the overlapping area, extracting a camera gamma value for the second area, calculating a reference grayscale value in the overlapping area, using the camera gamma value for the second area, generating a corrected luminance value of the overlapping area by applying weights on the basis of the position to the reference grayscale value, generating compensation data from the corrected luminance value, and transmitting the compensation data to a display device.

Abstract: The present disclosure relates to a method of calibrating luminance of a display panel and can accurately derive a calibration value for luminance of the display panel through a first luminance calibration step of calibrating the display panel using a first calibration value derived after the display panel is driven with a first grayscale value and a second luminance calibration step of calibrating the display panel using a second calibration value derived after the display panel calibrated using the first calibration value is driven with a second grayscale value.
