Quantum Dot LEDs

Home Applications Quantum Dot LEDs

QD LEDs is an emerging technology that promises to enhance current OLED displays with higher brightness, durability and colour purity. It will be an ultimate solution for flexible and curved displays in TVs, mobile and wearable devices, virtual and augmented reality glasses, automotive displays and signage. QDot™ Perovskite ABX3 Quantum Dots show great promise in that field, alongside with InP and CdSe quantum dots. QDot™ Perovskite ABX3 powders QDs are especially efficient for blue and green QD LEDs.

Technical data

Benefits of using QDot™ Perovskite Quantum Dots for QD LEDs:

  • High brightness (from 500 Cd/m2 for blue and from 1000 Cd/m2 for green lights)
  • High EQE (from 2% for blue and 5% for green)
  • Short decay time (< 5-20 ns)
