Abstract: A display device may compensate for such changes in characteristics of light emitting elements and transistors in pixels of a display. For example, a driving circuit of a display device may update a lookup table that stores one or more compensation values. Each compensation value may correspond to a characteristic change of a pixel. In some embodiments, the characteristic change of a transistor may be determined based on a sensing signal received from a dummy pixel. Accordingly, a display device may generate a compensation signal based on an actual characteristic change of the transistor in the pixel. The compensation signal may be used by the display device to compensate for pixel characteristic changes that occur over time. For instance, a display device may use such compensation signals to correct input signals (e.g., to generate a corrected output signal) to be applied to one or more pixels of a display.
