Discussed are an optical compensating system and method. Specifically, there can be provided an optical compensating method, comprising generating initial flat data for a display panel in a flat state displaying a test image, generating initial curve data for the display panel in a curved state displaying the test image, extracting point data for a plurality of points in the initial flat data and the initial curve data, generating deviation data using the point data, generating a curve data map by applying a weight according to a curvature at each point to the deviation data, generating final curve data by applying the curve data map to the initial curve data, and generating compensation data from the final curve data.

Optical compensating system and method

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.

Method to calibrate the luminance of the display panel

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.
