    Abstract: A display panel of a display device includes: first light emitting elements located in a first row, second light emitting elements located in a second row adjacent to the first row, first pixel circuits located in the first row, and second pixel circuits located in the second row. Each of the first pixel circuits drives a first light emitting element, located in a column the same as a column in which the each of the first pixel circuits is located, among the first light emitting elements. At least one second pixel circuit of the second pixel circuits drives a second light emitting element, located in a column different from a column in which the at least one second pixel circuit is located, among the second light emitting elements.

    Abstract: A pixel capable of displaying an image with uniform brightness is disclosed. In one aspect, the pixel includes an organic light emitting diode (OLED), a first transistor for controlling an amount of current that flows from a first power supply to a second power supply via the OLED in response to a voltage applied to a first node. The pixel also includes a second transistor that is coupled between a bias power supply and the first node and whose gate electrode is coupled to an emission control line. The pixel further includes a third transistor that is coupled between an anode electrode of the OLED and a feedback line and whose gate electrode is coupled to a control line.
