Laser displays, which exploit characteristic advantages of lasers, represent a promising next-generation display technology based on the ultimate visual experience they provide. However, the inability to obtain pixelated laser arrays as self-emissive full-color panels hinders the application of laser displays in the flat-panel sector. Due to their excellent optoelectronic properties and processability, organic materials have great potential for the production of periodically patterned multi-color microlaser arrays. Here, we demonstrate for the first time full-color laser displays on precisely patterned organic red-green-blue (RGB) microlaser matrices through inkjet printing. Individual RGB laser pixels are realized by doping respective luminescent dyes into the ink materials, resulting in a wide achievable color gamut 45% larger than the standard RGB space. Using as-prepared microlaser arrays as full-color panels, we achieve dynamic laser displays for video playing through consecutive beam scanning. These results represent a major step towards full-color laser displays with outstanding color expression.
激光显示利用了激光的固有特点，代表了一种很有前途的下一代显示技术，其终极视觉体验令人期待。然而，由于无法获得像素化的激光阵列作为自发光全彩面板，激光显示在平板领域的应用受到了限制。有机材料具有出色的光电性能和可加工性，非常适合制作周期性图案化的多色彩微激光阵列。在这里，我们首次通过喷墨打印在精确图案化的有机红绿蓝（RGB）微激光矩阵上展示了全彩色激光显示。通过将各自的发光染料掺杂到油墨材料中，实现了单个 RGB 激光像素，从而实现了可实现的色域比标准 RGB 空间大 45%。使用制备好的微激光阵列作为全彩面板，我们通过连续光束扫描实现了动态激光显示，可用于视频播放。这些结果标志着在具有出色色彩表现力的全彩色激光显示方面迈出了重要一步。
