Perovskite Nanocrystals in Glass for High Efficiency and Ultra-High Resolution Dynamic Holographic Multicolor Display

• • Achieved a record PLQY of 36% for pure blue emission (<480 nm) in PNCs-glass composites, overcoming the longstanding challenge of low efficiency in blue emitters and enabling high-brightness blue pixels for full-color displays. • • Demonstrated a pixel density of 20,247 PPI in a dynamic holographic multicolor display by integrating PNCs-glass with an SLM and CGHs, far exceeding conventional display resolutions and facilitating ultra-high-definition near-eye displays. • • The CIE 1931 color gamut covers 112.7% of the NTSC standard, ensuring vivid and accurate color reproduction for next-generation display applications. • • The vertically stacked multilayer architecture eliminates color filters, improving light utilization efficiency and spatial resolution, with potential to reduce power consumption by up to 50% compared to conventional LCDs.
