In this article, red and green perovskite quantum dots are incorporated into the pixels of a flexible color-conversion layer assembly using microfluidics. The flexible color-conversion layer is then integrated with a blue micro-LED to realize a full-color display with a pixel pitch of 200 μm. Perovskite quantum dots feature a high quantum yield, a tunable wavelength, and high stability. The flexible color-conversion layer using perovskite quantum dots shows good luminous and display performance under different bending conditions; is easy to manufacture, economical, and applicable; and has important potential applications in the development of flexible micro-displays.
在本文中，利用微流体技术将红色和绿色钙钛矿量子点并入柔性颜色转换层组件的像素中。然后将该柔性颜色转换层与蓝色微型发光二极管集成，以实现像素间距为200μm的全彩显示器。钙钛矿量子点具有高量子产率、波长可调以及高稳定性的特点。使用钙钛矿量子点的柔性颜色转换层在不同弯曲条件下展现出良好的发光和显示性能；易于制造、经济且适用；并且在柔性微型显示器的开发中具有重要的潜在应用。
