Kopin Corporation announced in January 2020 that the company developed a new double-stack OLED architecture that enables brighter microdisplays with longer lifetime. Earlier Kopin announced a new 1.3" 2560x2560 OLED microdisplay, developed with Panasonic and Lakeside Optoelectronic, that uses the new double-stack architecture and achieves brightness of over 1,000 nits.

Kopin now announced that they have achieved a breakthrough color fidelity (> 115% sRGB) for its latest 1.3" 2.6K x 2.6K OLED display. Kopin believes that this is the world’s highest color fidelity achieved on dual-stack OLED microdisplays - equal to that on the best single-stack OLED microdisplays.

To achieve this high color fidelity in a tandem OLED, Kopin incorporated a specially configured anode structure in the silicon backplane to suppress the color mixing between the dual OLED emitter layers. Kopin brands its new technology as ColorMax, and it believes it will be applicable to all OLED microdisplays using dual-stack OLED structures.
