Display system and method of compensating image of display panel using the same

A display system comprising:

• a measurer which measures an image at a measuring point o a display panel to generate measured data;
• a measured data filter which removes a false measured data exceeding an allowable range among the measured data;
• and
• a compensation data generator which generates representative compensation data compensating the image based on the measured data in which the false measured data is removed,
• wherein the measured data filter comprises:
• a single measurer filter which removes a data outside a first allowable range among first data measured multiple times by a first unit measurer of the measurer;
• and
• a multi measuring point filter which replaces data outside a second allowable range among second data measured at adjacent measuring points in a measuring point group of the measurer with replacement data.

A method of compensating an image of a display panel, the method comprising:

• measuring an image at a measuring point of the display panel to generate measured data;
• determining, as a noise, a false measured data, which is outside an allowable range, among the measured data generated by measuring the image at the measuring point of the display panel, and removing the false measured data from the measured data;
• generating representative compensation data for compensating the image based on the measured data in which the false measured data is removed;
• interpolating the representative compensation data corresponding to the measuring point of the display panel to generate an interpolation compensation data;
• and
• generating an extrapolation compensation data corresponding to a display area outside an outermost measuring point based on an outermost representative compensation data corresponding to the outermost measuring point,
• wherein the removing the false measured data comprises:
• removing a data outside a second allowable range among second data measured at adjacent measuring points in a measuring point group of a measurer;
• and
• replacing the removed data with replacement data.
