Research on Improving Thin-Film Pixel Uniformity for 300ppi Pixels Using Inkjet Printing Process

Abstract

This study explores inkjet printing for uniform thin-film fabrication in 300 PPI-class displays. By optimizing drying conditions such as natural and vacuum drying, the material flow within pixels was controlled, minimizing defects like coffee-ring effects. The results demonstrate improved pixel uniformity, highlighting inkjet printing’s potential for high-resolution display manufacturing.
