    Abstract: The present invention provides an OLED display device including a display panel, a data driver and a timing controller. The display panel has sub-pixels for displaying images. The data driver supplies a data signal to data lines of the sub-pixels. The timing controller supplies the data signal to the data driver and controls the data driver. The data driver outputs a stress prevention voltage for preventing application of stress to driving transistors included in the sub-pixels in response to a stress compensation signal output from the timing controller, and the stress prevention voltage is applied to M (M being an integer equal to or greater than 1) sub-pixels selected per frame.

    Abstract: A display device includes a display panel, a sensing circuit, and a compensation circuit. The sensing circuit senses a current generated by a pixel of the display panel. The sensing circuit includes an integrator circuit, a comparator, and a counter. The integrator circuit is initialized to have a first reference voltage as an output. The output of the integrator circuit changes with a rate according to the sensed current. The comparator compares the output of the integrator circuit to a second reference voltage. The counter determines a time for the output of the integrator circuit to reach the second reference voltage from the first reference voltage. The compensation circuit receives the determined time and determines a compensation amount from the received time. The compensating circuit further compensates a display voltage for the pixel by the determined compensation amount in a subsequent display frame of the display device.
