Hyewon Jung, Changho Cho, and Kyungjun Kim (LG Chem, Ltd., Korea)
Abstract: In this study, we introduced the fabrication of color filter array on the transparent polyimide film using the coating plastic process. Properties of color resists at various curing temperature and a carefully controlled film forming process are investigated for the color filter array of top emiting structure in White OLED display. Transparent polyimides were synthesized with various molecular composition to optimize the high transparency and high thermal durability with low thermal expansion coefficient to prevent warpage during fabrication process. Furthermore, our novel release process is an alternative method of conventional laser release process. This technique enables low display manufacturing cost as well as mass production with high reliability.
