Frequency variable display apparatus

Abstract

A display apparatus includes a subpixel including a driving transistor having a gate electrode connected to a first node and a source electrode connected to a second node, a light emitting element having an anode electrode connected to the second node, and a storage capacitor having one electrode connected to the first node and another electrode connected to the second node, a data line configured to transfer a data voltage to the first node in a gate-source setting period, and a reference voltage line configured to transfer an initialization voltage to the second node in the gate-source setting period. A voltage level of the initialization voltage increases as the light emitting element is degraded.
