Abstract: A pixel and a display device including the pixel are disclosed. The pixel comprises a first transistor, a second transistor, a third transistor, a fourth transistor, a fifth transistor, a sixth transistor, a seventh transistor, an eighth transistor, a first capacitor, and a light emitting element. The eighth transistor includes a gate electrode configured to receive a second data voltage, a first electrode connected to a fourth node, and a second electrode configured to receive an initialization voltage. The eighth transistor adjusts a voltage level of the first capacitor based on a difference between the voltage level of the first capacitor and a level of the second data voltage.

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.
