Abstract
This paper reported on the development of a Mura-free and high precise printing to realize high-resolution organic light-emitting diode and quantum dot light-emitting diode display panels with a G8.5 glass substrate. To realize Mura-free printing, we developed the single-path print line head and the new pixel volume adjustment system with a pixel volume variation of ±0.8%. And to realize high precise printing, we developed the G8.5 table system that compensated for the drop position by changing the jetting time of each nozzle. And verified a drop position accuracy of ±2.1 μm. By combining these technologies, we achieved Mura-free 220-ppi printing on the G8.5 table.
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.
