Incorporating perovskite nanocrystals (PNCs) in the glass matrix has been demonstrated to be an effective route to improve their stability for long-term operation. However, simultaneously achieving high luminance and high photoluminescence (PL) quantum yield (QY) is challenging. Herein, we report a strategy that employs fluoride ion doping to modify the three-dimensional glass network, thereby optimizing the crystallization behavior of PNCs and achieving both high luminance and high PLQY in full-spectrum. Leveraging these high-performance transparent composites, we constructed a dynamic holographic multicolor display system by integrating with a spatial light modulator (SLM), achieving a pixel density as high as 20,247 pixels per inch (PPI). We further propose a vertically stacked, multilayer full-color display architecture that overcomes the limitations of color filters in light-utilization efficiency and the bottlenecks of conventional planar sub-pixel layouts in terms of spatial utilization and resolution.
