摘要

Large-scale red, green, and blue (RGB) microlaser arrays capable of exhibiting full-color laser emissions are urgently desired for high-performance flat-panel laser displays. With excellent solution processability and optoelectronic properties, organic materials are promising candidates for full-color microlasers; however, the heterogeneous integration of full-color microlasers remains a challenge due to their poor solution stability to withstand multistage solution processing. Here, a robust in situ cross-linking strategy is proposed to enable orthogonal processing of organic microlasers to heterogeneously integrate large-scale full-color organic microlaser arrays. The organic microlasers with controlled physical dimensions and spatial locations are fabricated with an electron beam (e-beam) induced in situ polymerization reaction. Profiting from enhanced orthogonality of microlasers, large-scale pixelated RGB microlaser arrays are monolithically integrated through successive e-beam patterning processes. Laser emissions in the RGB microlaser pixels cover a color gamut 41% larger than the standard RGB space, with which flexible full-color organic laser display patterns with a resolution of 254 dpi on a centimeter scale is obtained. The scalable heterogeneous integration platform reported in this work will pave a new avenue for the efficient construction of large-scale high-performance organic integrated optoelectronic devices.
