Publication number: 20240085788Abstract: An object of the present disclosure is to improve display reliability and lifetime as well as vivid colors. When there remain residues in the washing part due to incomplete removal during the developing step, it can cause dark spots or pixel off due to the residues, and thus residue-free pixels can be formed by optimizing the temperature and time for developing. Additionally, when the amount of outgas in the panel after post-baking is 15 ppm or more, it may cause a reduction in luminance and lifetime due to pixel shrinkage. Therefore, in order to minimize the amount of outgas after completion of the post-baking process, the generation of outgas in the panel state can be minimized by generating sufficient fume in the post-baking step, in addition to forming clean pixels in the developing step.Type: ApplicationFiled: August 16, 2023Publication date: March 14, 2024Applicant: DUK SAN NEOLUX CO., LTD.Inventors: Jun BAE, Changmin LEE, Yeon Soo LEE, Jun Ki KIM, Jin Hyun KIM, Ju Cheol KWON, Soung Yun MUN, Kyung Soo KIM
