A display device includes a display panel including pixels, a data driver receiving sensing data corresponding to a driving current value of a driving transistor of each of the pixels, and a driving controller calculating a change amount of the sensing data, determining bad pixels based on the change amount of the sensing data, and performing a panel protection operation based on a number of the bad pixels.

Display device and method of driving the same

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.

Display apparatus and method of driving the same

Disclosed are an active matrix-based electronic apparatus and a method of driving the same. More particularly, a pixel circuit of an electronic apparatus according to an embodiment of the present disclosure may include a light-emitting driver configured to apply a forward bias to a light-emitting device in an emission mode to control light to be emitted through the light-emitting device; a sensing driver configured to apply a non-forward bias to the light-emitting device in a sensing mode to control an electrical signal corresponding to light incident on the light-emitting device to be generated; and a reader configured to read intensity of light corresponding to the generated electrical signal.
