During DisplayWeek 2023, BOE demonstrated a new OLED microdisplay. The panel is 1.3" in size, and it offers a 3552x3840 resolution (4031 PPI), a refresh rate of 90Hz, and a color gamut of 90% DCI-P3.
This is BOE's largest and highest-resolution OLED microdisplay to date. BOE's current OLED microdisplays, already in production, include a 0.39", 0.49" and 0.71" FHD panels (all of which are available on the OLED marketplace, by the way).
The 1.3" display is by far BOE's largest. During the exhibition, BOE mentioned that this display supports Foveal Mode - which means putting this display on top of a larger AMOLED display, to provide high-resolution and features in the center of the user's vision. It's not clear what BOE means by 'supporting' such a design.
Apple is reportedly using a foveated design for its first VR headset, which will likely be announced next month. Apple is said to be using a 4K OLED microdisplay for its first VR headset - produced by Sony. It is highly likely that BOE is aiming to become a supplier for Apple's headset, and has developed this display with Apple in mind.
