Abstract: A display apparatus includes a display panel including pixels, a gate driver outputting gate signals to the pixels, a data driver outputting data voltages to the pixels, a sensing circuit receiving sensed signals from the pixels, a power voltage generator applying a power voltage, and a driving controller for stopping the display panel, the gate driver, the data driver, and/or the power voltage generator when the display panel is determined to be defective. The driving controller selects a first-mode threshold set or a second-mode threshold set based on an initial value set related to the sensed signals for determining whether the display panel is defective. Thresholds in the first-mode threshold set respectively correspond to and are respectively unequal to thresholds in the second-mode threshold set.

Abstract: A method of driving a display panel includes compensating first pixel data corresponding to a first pixel of a plurality of pixels in the display panel based on at least one of a first decision, a second decision, or a third decision and generating a first data voltage corresponding to the compensated first pixel data. The first data voltage is applied to the first pixel through a data line. The first decision includes determining, based on a position of the first pixel, whether compensation for the first pixel data is required. The second decision includes determining, based on previous subpixel data and present subpixel data for the first pixel, whether the compensation for the first pixel data is required.
