SEL demonstrates a 15,000 nits direct-emission tandem OLED microdisplay

Japan's Semiconductor Energy Laboratory (SEL) demonstrated its latest OLED microdisplay technology at Displayweek 2024. The 1.5" 3840x2880 (3207 PPI) display achieves a brightness of 15,000 by using a tandem architecture and a direct-emission design. The OLED deposition was performed using photo-lithography. 

This is an impressive display, with very high brightness. It surpasses LGD's 10,000 nits microdisplay also shown at Displayweek, which uses a white-OLED with color filter design, and a microlens array. It matches eMagin's 15,000 nits microdisplay, demonstrated back in 2023 - which is a single stack device.


Recently we have seen several OLED microdisplay technologies (MLA, direct-emission, new emitters, etc.) , that manage to increase brightness from around the 5,000 nits level to around 15,000. Display developers can combine these technologies and we estimate that within a few years it will be possible to develop OLED microdisplays that reach around 30,000 nits brightness, and likely more further on.
