A 326ppi 1.4” circular RGB OLED display that has 54.1% aperture ratio is demonstrated. The RGB OLED display was fabricated with a novel metal‐mask‐free deposition and lithography OLED patterning technology. The obtained large aperture ratio is nearly double of today's standard RGB evaporation OLED displays. Japan Display Inc. is registering the trademark “eLEAP” for the displays made with lithography OLED patterning. In this article, we will discuss the breakthroughs of eLEAP in design, process, and performance points of view.
