WO/2010/023270 is referenced by 95 patents.

The present invention relates to a method for compensating ageing effects of pixel outputs displaying an image on a display device, comprising: - displaying a first image on an active display area (6) on the display device (1 ) having a first plurality of pixels; - displaying a second image on a sub-area (7) of the display device (1 ) and having a second plurality of pixels, the active display area (6) being larger than the sub-area (7) and the second image being smaller than the first image and having fewer pixels than the active display area (6); - driving the pixels of the sub-area (7) with pixel values that are representative or indicative for the pixels in the active display area (6); - making optical measurements on light emitted from the sub-area (7) and generating optical measurement signals (1 1 ) therefrom, and - controlling the display of the image on the active display area (6) in accordance with the optical measurement signals (11) of the sub-area (7).
