Quantum dots (QDs) embedded in LGPs enable ultra-wide color gamut (WCG) displays. CdSe/ZnS QDs achieve 110% NTSC coverage, surpassing phosphor-based solutions by 30%. However, blue LED-induced QD degradation remains a challenge, with 15% luminance loss after 5,000 hours.
Core-shell QD encapsulation using silica shells improves stability. Tests show <5% efficiency drop over 10,000 hours at 85°C/85%RH. This enables automotive applications requiring AEC-Q102 compliance.
Patterned QD layers using inkjet printing achieve 100μm resolution. By concentrating QDs in high-brightness zones, systems maintain 80% color uniformity across 8K panels.
Health concerns regarding cadmium-based QDs are addressed via indium phosphide (InP) alternatives. These exhibit 85% quantum yield without toxic elements, suitable for medical imaging displays.
