The OLED Association reports that Shanghai Tianma demonstrated a new 5.5" Full-HD (400 PPI) AMOLED prototype. This is the highest-resolution display ever shown by the Chinese display maker, and reportedly they have adopted a subpixel scheme not unlike Samsung's Pentile technology. To achieve the high resolution, Tianma developed a dual-FMM technology in-house.
Tianma has been developing LTPS AMOLED technology for quite a while, and according to our information they are getting ready to release the first panels in 2016. Tianma has plans for three separate OLED production lines.
