The ink jet printing RGB patterning technology (“Printing Technology”) for OLED TV application is gathering momentum toward commercialization. main technical challenges of technology, are (1) to improve the panel performance fabricated by and (2) establish manufacturable G8.5/G11 MURA‐Free technology. Recently, has made tremendous progress in terms material performance( life time, current efficiency, color gamut driving voltage) including optimization top emission device architecture maturity ink‐jet ,such as high equipment equipped with excellent print‐head drop volume uniformity placement accuracy, formulation reliable jetting, hydrophobic bank material/design/process unique vacuum dry & bake process. TCL Group (Guangdong Juhua Printed Display Technology, Corporate Research, CSOT) been developing innovative flexible display since 2015. Based on development activities 31” 4K TV, H‐QLED TV(World 1 st Demo at CES 2019), FHD Flexible 4.92” (403ppi) resolution panel, latest breakthrough next generation premium discussed details.
