Qingsong Yuan

Title: Qingsong Yuan and His OLED Materials Patent.

Introduction

Qingsong Yuan is an inventor associated with Wuhan, China, whose patent work focuses on organic materials for organic light-emitting diode (OLED) devices. His disclosed invention addresses electron transport, hole blocking, and device efficiency.

Latest Patents

Yuan is listed with 1 patent: “Organic Compound and Application Thereof.” The patent describes an organic compound with a relatively deep lowest unoccupied molecular orbital (LUMO) energy level, which may lower the barrier to electron transport, improve electron injection, and reduce OLED operating voltage. Its compounds also have relatively deep highest occupied molecular orbital (HOMO) energy levels, which may block holes and encourage more effective recombination of holes and electrons in the light-emitting region.

The invention proposes using the compounds in an electron transport layer, a hole-blocking layer, or both. These materials may help reduce device voltage and power consumption, improve luminescence efficiency, and extend operating lifetime.
