Despite their advantages, QLEDs face several challenges:
Cost: The production of quantum dots can be expensive, which translates to higher costs for QLED displays. Material Stability: Ensuring the long-term stability of quantum dots, especially under high brightness and prolonged use, is crucial. Environmental Concerns: Some quantum dots contain toxic materials like cadmium, raising environmental and health concerns. Researchers are working on developing cadmium-free quantum dots.
