Abstract:
Systems and methods are provided to compensate image data for display on a curved display. A pixel uniformity compensation factor may be applied based on a pixel uniformity compensation factor map that is calibrated to the display panel while the display panel has a flat shape, and a panel curvature compensation factor may be applied when the image content is to be displayed while the display panel has a curved shape. The panel curvature compensation factor may be based on a panel curvature compensation factor map that is calibrated to the display panel after the display panel is bent from the flat shape to the curved shape.
