Abstract
AbstractThis 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.
