Abstract: A display device and a method for correcting an image of the display device are disclosed. In one aspect, the display device includes a display panel including a plurality of pixel lines configured to be selected as at least one of data insertion lines and data deletion lines. The display device also includes an image corrector configured to receive input image data, select the data insertion lines and data deletion lines when the input image data represents an image including a static image block, insert second image data corresponding to the data insertion lines into the input image data, and delete first image data corresponding to the data deletion lines from the input image data so as to generate corrected image data including a shifted static image block.

Abstract: A method of driving an OLED display device includes receiving image data. A load value is determined for each sub-pixel. A first load value is set to a largest load value determined for each sub-pixel. A first correction factor is calculated that decreases as the first load value increases, when the first load value is greater than a first threshold. A second load value is calculated based on the image data and current contribution weights for the sub-pixels. A second correction factor is calculated that decreases as the second load value increases, when the second load value is greater than a second threshold. Either the first correction factor or the second correction factor is selected. The image data is converted into output image data based on the correction factor. An image corresponding to the output image data is displayed.
