US 2019/0197965 A1 · Organic Light-Emitting Display Device

Abstract

Disclosed is a display device including a substrate, a bottom shield metal layer, a driving transistor, and an organic light emitting diode (OLED). The bottom shield metal layer is on the substrate, and is coupled to a voltage source. The driving transistor is above the bottom shield metal layer. The driving transistor includes a first terminal (e.g., a source terminal), and a second terminal (e.g., a drain terminal). The first terminal of the driving transistor is coupled to a reference voltage for setting a voltage value at the first terminal. The coupling of the bottom shield metal layer to the voltage source is independent of the coupling of the first terminal to the reference voltage. The OLED includes an electrode that is coupled to the first terminal of the driving transistor.
