The Age of Screen Enlightenment – Space & Physics | Weizmann Wonder Wander

Digital displays comprising organic materials have brought about a new era in consumer electronics, helping to mass produce brighter screens that hold numerous advantages over those made of regular crystalline materials. These organic light-emitting diodes, or OLEDs, can, for example, enable the manufacture of foldable phones that double their screen size when opened.

Yet even the most advanced OLED displays in production today waste about half of the light they emit – a shortfall that had seemed unavoidable because it stems from the physics of light. A new study, led by a Weizmann…
