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.
