Abstract

Laser patterning of perovskite is a novel technology with the advantages of high speed, programmability, and maskless, which is ideal for fabricating micro light-emitting diodes (micro-LED) color conversion layers (CCL). This work reports a method for laser in situ synthesis of wide bandgap tunable perovskite with an emission spectrum from 475 to 667 nm. Based on the photonic effect of continuous wave (CW) laser and the thermal quenching phenomenon of perovskite, ultra-high precision patterning with a minimum linewidth of 750 nm and a maximum dot-pixel per inch (PPI) of 5684 is achieved. More importantly, significant improvements in perovskite stability and integration of red-green dual-color dot arrays are achieved through in-depth studies of polymer matrices and precursor solvents. The red-green dual-color integrated dot arrays using blue micro-LED chips, which is a great impetus to the research of micro-LED full-color displays, are also successfully excited.

激光原位合成宽禁带可调钙钛矿及其在微型led中的应用

钙钛矿激光图像化是一种高速、可编程、无掩模的新技术，是制造微型发光二极管（micro- led）彩色转换层（CCL）的理想技术。本文报道了一种激光原位合成宽禁带可调钙钛矿的方法，其发射光谱为475 ~ 667nm。基于连续波（CW）激光的光子效应和钙钛矿的热猝灭现象，实现了最小线宽为750 nm、最大点像素每英寸（PPI）为5684的超高精度图像化。更重要的是，通过对聚合物基质和前驱溶剂的深入研究，实现了钙钛矿稳定性和红绿双色点阵列集成的显著改善。采用蓝色微型led芯片的红绿双色集成点阵列也被成功激发，这对微型led全彩显示的研究起到了很大的推动作用。
