FREQUENCY VARIABLE DISPLAY DEVICE

Abstract

A display device has a subpixel (SP1, ..., SP4) comprising a drive transistor with a gate electrode connected to a first node (N1) and a source electrode connected to a second node (N2), a light-emitting element (OLED) with an anode electrode connected to the second node (N2), and a storage capacitor (Cst) with one electrode connected to the first node (N1) and another electrode connected to the second node (N2), a data line (DL) configured to transmit a data voltage (Vdata) to the first node (N1) during a gate-source setting period, and a reference voltage line (RL) configured to transmit an initialization voltage (VpreR) to the second node (N2) during the gate-source setting period.The initialization voltage (VpreR) level increases as the light-emitting element (OLED) deteriorates.
