43‐1: Invited Paper: High PPI Printed OLED Display Developments

This paper reviews the progress of printed OLED technology in terms of high PPI, including pixel design and printing process. In addition, we have introduced a 300ppi plus top‐emission device using a new pixel design strategy that integrates a triangular pixel arrangement and a narrow channel structure. This technology enables printer to achieve the high resolution capabilities of monitor and notebook applications.
