Laser displays, benefiting from the characteristic merits of lasers, have led to the revolution of next-generation display technologies owing to their superior color expression. However, the acquisition of pixelated laser arrays as self-emissive panels for flat-panel laser displays remains challenging. Liquid crystal (LC) materials with excellent processability and optoelectronic properties offer considerable potential for the construction of highly ordered multicolor laser arrays. Here, we demonstrate flat-panel laser displays on LC microlaser pixel arrays through a microtemplate-assisted inkjet printing method. Individual organic red-green-blue (RGB) microlaser pixel arrays were obtained by doping dyes into LCs with photonic band edges to obtain single-mode RGB lasing, leading to a much broader color gamut, compared with the standard RGB color space. Then we acquired periodically patterned RGB pixel matrices by positioning LC microlasers precisely into highly ordered arrays, according to the well-organized geometry of the microtemplates. Subsequently, we demonstrated full-color flat-panel laser displays using the LC microlaser pixel matrices as self-emissive panels. These results provide valuable enlightenment for the construction of next-generation flat-panel laser display devices.

基于液晶微激光器阵列的平板激光显示器

受益于激光的特性，激光显示器凭借其卓越的色彩表现力，引发了下一代显示技术的革命。然而，获得像素化激光器阵列作为用于平板激光显示器的自发射面板仍然具有挑战性。具有出色的可加工性和光电性能的液晶（LC）材料为构建高度有序的多色激光阵列提供了巨大的潜力。在这里，我们通过微模板辅助喷墨打印方法在LC微激光像素阵列上演示了平板激光显示器。通过将染料掺入具有光子能带边缘的LC中以获得单模RGB激光，获得单个的有机红绿蓝（RGB）微激光像素阵列，从而获得更宽的色域，与标准RGB颜色空间相比。然后，根据微模板组织良好的几何结构，通过将LC微激光精确定位到高度有序的阵列中，我们获得了周期性图案化的RGB像素矩阵。随后，我们展示了使用LC微激光像素矩阵作为自发射面板的全彩色平板激光显示器。这些结果为下一代平板激光显示设备的构造提供了宝贵的启示。
