Advanced Materials Interfaces, EarlyView.A pixelated full‐color display is driven by a 1064 nm near‐infrared laser without electrical wiring. A graphite photothermal layer converts light into heat, while an aluminum heat‐spreading layer redistributes it for uniform color within each pixel. Optimizing pixel size and spacing suppresses thermal crosstalk, enabling non‐contact reproduction of ...
