"more energy-efficient/ stable... electroluminescent response speed of QLEDs are influenced by remnants of electrical pulses applied to them in past, linked to deep-level hole trap energy states inhabiting device's amorphous polymer semiconductors... specialized microstructures... when driven at higher pulse frequencies, devices respond faster, enabling operation at modulation frequencies >100 MHz/ data-transmission rates up to 120 Mbps, useful for high-speed optical communication..."
