    Abstract: A pixel includes a driving circuit, a first organic light emitting diode, a second organic light emitting diode, and a self-repair circuit. The driving circuit supplies current based on a data signal supplied through a data line. The first organic light emitting diode is coupled to the driving circuit through a first current path. The second OLED is coupled to the driving circuit through a second current path. The self-repair circuit interrupts the first current path and supplies the current to the second current path when the first organic light emitting diode has a defect.

    Abstract: A display device includes a display panel, a data driver which provides data voltages to the display panel, and a controller which provides output image data to the data driver. The controller includes a data line memory which stores input image data for each pixel row of the display panel, an address line memory which stores addresses for the input image data, and a data serialize block which generates the output image data provided to the data driver by rearranging the input image data stored in the data line memory based on the addresses stored in the address line memory.

    Abstract: A method of operating an organic light-emitting diode (OLED) display and an OLED display are disclosed. In one aspect, the method includes measuring an extent of degradation of the OLEDs and determining a power supply voltage increment based at least in part on the measured extent of degradation. The method further includes increasing a power supply voltage applied to the pixels by the determined power supply voltage increment and increasing the high data voltage and the low data voltage in proportion to the determined power supply voltage increment.
