"OLEDs built on flat panels driven at high currents causes burn out/ degrade quickly, overcome creating micro-ridges 0.1 mm tall onto glass surface increasing surface area... allows more light-emitting material packing into same panel footprint, producing same total light at lower individual brightness/ lower current... white OLED stacking red, green, blue layers... 2.7x longer lifespan, 40% higher light extraction efficiency... 3D shape helps light bounce out, not trapped... curved or foldable architectural lighting"
