Abstract: A display device includes a display panel including a plurality of pixels, a gate driver which provides a gate signal to corresponding pixels of the plurality of pixels, a data driver which provides a data voltage to the corresponding pixels of the plurality of pixels, a power voltage generator which provides a pixel power voltage to each of the plurality of pixels, and provides a gate power voltage to the gate driver, and a controller which provides a gate control signal to the gate driver. The pixel power voltage, the data voltage, and the gate control signal sequentially have a ground voltage level in response to a power-off signal.

Abstract: A thin film transistor is disposed on a substrate. A via insulating layer having a via hole covers the thin film transistor. A pixel electrode is disposed on the via insulating layer and electrically connected to the thin film transistor through the via hole. A first protection layer surrounds the pixel electrode. A pixel-defining layer covers an edge region of the pixel electrode and at least a portion of the first protection layer. The pixel-defining layer includes an opening through which an upper surface of the pixel electrode is exposed. An opposite electrode faces the pixel electrode. An intermediate layer is disposed between the pixel electrode and the opposite electrode.

Abstract: A display device includes: a memory, a driving controller, a light emitting element, a first transistor including a first electrode, a second electrode, and a gate electrode for receiving a data signal, a second transistor connected between a first driving voltage line and the first electrode of the first transistor and receiving a first emission signal, and a third transistor connected between the second electrode of the first transistor and the light emitting element and receiving a second emission signal. The first emission signal includes a compensation period and an emission period, and the memory stores instructions that, when executed by the driving controller, cause the driving controller to determine a compensation time of the compensation period depending on target luminance.

Abstract: A display device includes a substrate including a display area and a peripheral area disposed outside of the display area. The display area includes a plurality of pixels. The display device further includes an inorganic insulating layer disposed in the display area. The inorganic insulating layer includes a groove disposed in a region between the plurality of pixels. The display device further includes an organic material layer filling the groove, a first connection wiring, and a second connection wiring. The first connection wiring is disposed on the organic material layer, overlaps the plurality of pixels, and extends in a second direction. The second connection wiring is insulated from the first connection wiring, and extends in a first direction that crosses the second direction.
