LG Display has been developing OLED microdisplay technologies for several years (branding these as OLEDoS), and last year it was reported that LGD is planning to build its first production line, as hoping to supply OLED Microdisplay to Apple in the future. LG is reportedly started ordering deposition equipment from Korea-based OLED equipment maker Sunic System.
According to the Korean publication The Elec, LGD has decided not to build an OLED microdisplay production line, at least for now. The company will continue its R&D project, though.
It is not clear what is behind LGD's decision. It could be a financial decision - the company has been recently losing money as demand for displays is weak. It could also be that it will require more R&D effort to gain an edge over existing microdisplay makers, especially Chinese makers that are able to offer high quality displays at attractive prices.
It could also be that LGD is not seeing a large demand for OLED microdisplays in the near future.
In 2020 LG Display unveiled its OLEDoS brand of OLED microdisplays. LGD's display was a 0.42" 1280x720 (3,500 PPI) panel that uses a color-filter based design. The display offers a brightness of 5,000 nits. In 2021 LGD revealed that it is developing a 1.16" 3K OLED microdisplay, and also a 4K one. It is likely that this 4K display is targeting Apple's future device.
