Abstract: A method of operating a display device may include the following steps: in a first frame period, before turning off a gate initialization transistor, changing an initialization voltage from a first level to a second level and subsequently returning the initialization voltage to the first level; in a second frame period, before turning off the gate initialization transistor, changing the initialization voltage from the first level to the second level and/or a third level and subsequently returning the initialization voltage to the first level. The display device may include the gate initialization transistor and a driving transistor. A first electrode the gate initialization transistor may receive the initialization voltage. A second electrode of the gate initialization transistor may be electrically connected to a gate electrode of the driving transistor. The first level, the second level, and the third level may be unequal to each other.

Abstract: A display device includes a plurality of pixels. Each pixel includes a first transistor that controls an amount of current received from a first power supply voltage line connected via a second node to an organic light emitting diode in response to a voltage of a first node, a second transistor connected between a data line and the second node and that includes a first gate electrode connected to a first scan line, a light emitting line connected to a gate electrode of at least one light emitting transistor located in a current path between the first power supply voltage line and the organic light emitting diode, and a seventh transistor connected between one of at least one second gate electrode of the second transistor and the light emitting line. Accordingly, a threshold voltage of a switching transistor included in each of the plurality of pixels may be negatively shifted.
