Optical engine for realizing Micro-LED colorized projection

The invention provides an optical engine for realizing Micro-LED colorized projection. The optical engine comprises a Micro-LED chip, a driving circuit substrate, a micro lens array, a quantum dot color conversion film, a color combination prism and a projection objective. The Micro-LED chip array is installed on the driving circuit substrate, the quantum dot color conversion film is tightly attached to the upper portion of the Micro-LED chip array, and the micro lens arrays are installed on the quantum dot color conversion film and correspond to the Micro-LED chip array one to one. According to the invention, the Micro-LED single chip can realize full-color projection at any angle in a color combination manner, the cost of projection colorization is reduced, and higher flexibility and smaller volume are achieved. 本发明提供了一种实现Micro-LED彩色化投影的光学引擎，包括Micro-LED芯片、驱动电路基板、微透镜阵列、量子点色转换膜、合色棱镜以及投影物镜。所述的Micro-LED芯片阵列安装在驱动电路基板上，量子点色转换膜紧贴于Micro-LED芯片阵列上方，微透镜阵列安装在量子点色转换膜上与Micro-LED芯片阵列一一对应。本发明可实现Micro-LED单芯片以任意角度合色实现全彩化投影，降
