US 2026/0073868 A1 · PIXEL CIRCUIT AND DISPLAY APPARATUS INCLUDING THE SAME

Abstract

Disclosed in the present disclosure is a pixel circuit. The pixel circuit according to an embodiment of the present disclosure includes a first node connected to a driving voltage line configured to receive a first constant voltage, a third node connected to a fourth node that is connected to a light-emitting element, a first driver including a first driving element, and a second driver including a second driving element. The first driver and the second driver may be alternately driven for each frame. In a pixel circuit according to the present disclosure, a threshold voltage shift phenomenon and a deterioration phenomenon of the driving element may be prevented or suppressed.
