The Ultimate Glow Up: NUS CDE Researchers Push Flexible Display Brightness to New Records
AI-summarised brief · reviewed before publication
Researchers at the National University of Singapore’s College of Design and Engineering, in collaboration with IMRE, IHPC and ASTAR, have broken the brightness barrier for electrochemiluminescent (ECL) displays, achieving 1,552 cd/m²—three to four times brighter than typical indoor smartphone screens and over three times the previous ECL record. The advance stems from swapping the conventional bulky‑ion ionic liquid for a smaller‑anion formulation that speeds electron exchange and dissolves more light‑emitting dye, and from redesigning the electrode pair with a textured reactive surface, a transparent counterpart, and a rear silver mirror. The new devices emit a steady glow, run on a small battery, and retain brightness 82 × longer over cycling tests, sustaining two‑hour continuous operation. Demonstrations include a colour‑changing glucose‑monitor skin patch, an underwater‑readable diver’s sleeve, and a flexible seven‑segment numeric display.
💡 Why It Matters
- · By delivering smartphone‑level brightness in a thin, low‑power, flexible format, the breakthrough makes wearable and submerged displays viable for real‑time health monitoring and niche marine applications.
