Just as LED manufacturers are struggling in face of the declining profit in the lighting sector and the contraction of the backlight market, OLED emerges as the latest threat to their survival. Elevated by its potential to become one of Apple’s core technologies, OLED has expanded rapidly into various display and niche applications. While the LED industry expects even more challenging times ahead, new opportunities also appear on the horizon. Micro LED, which has been incorporated into Apple and Sony’s product roadmaps, are poised to become a commercially viable display technology that can be mass produced for everyday applications.
