摘要

在本文中，我们获得了QLED顶部发射旋涂装置的最佳结构。同时，我们还成功开发了具有高稳定性的量子点和ZnO油墨材料。凭借顶部发射装置结构和稳定的油墨材料，我们通过控制喷墨打印后的干燥过程来优化每一层薄膜的形态。通过使用优化的喷墨打印工艺制备的联合器件的发射面积等于像素的设计面积，边界清晰，单个子像素内的电致发光形态均匀，像素之间的发光没有显著差异。最后，我们组装并制造了一个55英寸的。8K AMQLED显示器，具有116%NTSC的色域。

Development of the ink-jet printing technology for 55-inch 8K AMQLED display

In this paper, we obtained the optimal structure of QLED top-emission spin-coating device. Meanwhile, we also have successfully developed quantum dots and ZnO ink materials with high stability. With the top-emission device structure and stable ink materials, we optimize the morphology of every film by controlling the drying process after ink-jet printing. The emission area of united devices prepared by using the optimized ink-jet printing process is equal to the designed area of pixels, with clear boundaries, uniform electroluminescent morphologies within a single sub-pixel, and no significant difference in luminescence between pixels. Finally, we assembled and fabricated a 55-in. 8K AMQLED display with a color gamut of 116% NTSC.

期刊介绍： The Journal of the Society for Information Display publishes original works dealing with the theory and practice of information display. Coverage includes materials, devices and systems; the underlying chemistry, physics, physiology and psychology; measurement techniques, manufacturing technologies; and all aspects of the interaction between equipment and its users. Review articles are also published in all of these areas. Occasional special issues or sections consist of collections of papers on specific topical areas or collections of full length papers based in part on oral or poster presentations given at SID sponsored conferences.
