Late-News Poster: Fabrication of Completely Uniform OLED Display Using an Improved Inkjet Method

摘要

Inkjet is expected to be a promising manufacturing method for large sized OLED displays. In this development, Inkjet quality was focused and practical solutions were explored. The developed precise ink volume control method with improved Inkjet print heads enabled uniform material deposition into pixels. Complete uniformity of light emission was achieved, thus proving product quality of the Inkjet method. The approach was applied to a large sized display to demonstrate that the improved Inkjet method is particularly useful for fabricating large sized OLED displays in respects of both quality and productivity.
