  • Patent number: 10720100
    Abstract: An organic light emitting display (OLED) device may include a display panel, a gate driver, a data driver, a timing controller and a deterioration compensation unit. The deterioration compensator may detect one or more deteriorated regions in the display region based on stress data of the respective pixels, the stress data being generated by counting input data corresponding to the respective pixels, and generate compensation data of pixels included in each of the deteriorated regions, based on the stress data of the respective pixels and sensing data for deteriorations of pixels included in two or more horizontal lines which are arbitrarily selected among horizontal lines corresponding to the deteriorated region.

  • Patent number: 10629118
    Abstract: An organic light emitting display device includes a display panel and a deterioration compensation unit. The display panel comprises a plurality of unit pixels each comprising at least three sub-pixels corresponding to different colors and an organic light emitting diode. The deterioration compensation unit generates deterioration estimation data of each of the sub-pixels based on cumulative data of each of the sub-pixels, generates first and second temperature deterioration data based on display temperature data corresponding to temperature of the organic light emitting display device, calculates an individual compensation gain corresponding to each of the sub-pixels based on the deterioration estimation data and the first and second temperature deterioration data, and corrects input data of each of the sub-pixels based on the individual compensation gain of each of the sub-pixels.
