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.
