Here we are, living in a world of Apple only just reaching 1920x1080 on its latest iPhone 6 Plus, while Japan's Semiconductor Energy Laboratory (SEL) working with Nokia on some truly groundbreaking OLED display prototypes. Back in June, the two unveiled a 5.9-inch 1280x720 (720p and 249 PPI) display that could be folded in two, or in three - with two different prototypes being used.
Well, SEL are back, showing off a new 8.7-inch AMOLED, with the resolution cranked up to 1920x1080 (1080p and 254 PPI). These new panels are touch-capable, and can be tri-folded with the single prototype. SEL has done this by utilizing their CAAS-OS (C-Axis Aligned Crystalline Oxide Semiconductor) backplane, as well as a WRGB structure. The panels themselves are less than 100μm thick, weighing just 6 grams.
SEL was also teasing their new super-high-resolution AMOLED display, which was just 2.8 inches, with a resolution of 2560x1440 - this provides the tiny little OLED display with a PPI of 1058. The company had a large viewfinder on-hand to better show off its incredible technology.
