Abstract: A display system includes a measurer, a measured data filter and a compensation data generator. The measurer measures an image at a measuring point of a display panel to generate measured data. The measured data filter removes a false measured data outside an allowable range among the measured data. The compensation data generator generates representative compensation data compensating the image based on the measured data in which the false measured data is removed.

Abstract: A display apparatus includes a display panel, a driving controller, and a data driver. The display panel is configured to display an image based on input image data. The driving controller is configured to determine whether the input image data include a display quality deteriorating pattern. The driving controller is configured to determine a first compensation value for compensating a first area disposed at a first side of a main area of the display quality deteriorating pattern and a second compensation value for compensating a second area disposed at a second side of the main area opposite to the first side of the main area, according to a position of the main area. The data driver is configured to apply a data voltage to the display panel using the first compensation value and the second compensation value.
