Optical compensating system and method

An optical compensating device, comprising:

• a camera configured to generate a photographed image for a display panel displaying a test image;
• a data converting module configured to convert a flat photographed image and a curve photographed image into initial flat data and initial curve data;
• a deviation data generating module configured to generate deviation data for the initial flat data and the initial curve data;
• a curve data map generating module configured to generate a curve data map by applying weights according to curvature of the display panel to the deviation data;
• a final curve data generating module configured to generate final curve data by applying the curve data map to the initial curve data;
• and
• a compensation data generating module configured to generate compensation data using the final curve data.

A display device, comprising:

• a display panel including a plurality of subpixels having a light emitting element;
• a gate driving circuit configured to supply a plurality of scan signals to the display panel;
• a data driving circuit configured to supply a data voltage to the display panel;
• a memory configured to store compensation data;
• and
• a timing controller configured to compensate for the data voltage using the compensation data, wherein the compensation data is generated by:
• generating initial flat data for the 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 weights according to 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.
