Ultra-high resolution and wide viewing-angle 651 ppi LTPS LCDs

Recently, mobile displays especially for smartphones have been rapidly shifted to provide a higher resolution of 300 pixels/inch (ppi) or more, along with a wider viewing angle, a higher contrast ratio and a slimmer border. From viewpoints of both human eye resolution limitation and current progress of communication infrastructure, displays with resolution of 500 ppi or more should be needed in the near future. We are now developing ultra-high resolution displays, whose performance and fundamental technologies are described in this paper. Also future trend and challenges are addressed.
