At SID Display Week 2023, BOE showcased a new 1.3-inch “4K” oled microdisplay. Public reports describe the panel at 3552×3840 resolution (4K-class) with ~4031 PPI and a 90 Hz refresh rate—positioning it among the highest-density near-eye displays demonstrated at the show.
1、 Why Micro OLED Matters for AR/VR
Many XR products still struggle with visible pixel structure and reduced clarity when viewed through near-eye optics. By pushing pixel density to microdisplay levels, micro oled helps reduce the “screen-door” sensation and supports a more natural, immersive image.Because OLED on silicon is self-emissive, it also delivers the familiar OLED strengths—deep blacks, high contrast, and fast response—while remaining small enough for compact optical engines used in AR glasses and VR headsets.
2、BOE’s 1.3-Inch 4K Micro OLED Highlight (SID 2023)
BOE presented its 1.3-inch 4K-class microdisplay as part of its XR technology lineup at Display Week 2023. The company highlighted ultra-high resolution (over 4000 PPI-class) for sharper, more immersive viewing, while industry coverage notes 90 Hz operation and ~4031 PPI.

3、Tandem OLED Direction: Higher Brightness, Better Efficiency
A major industry push for oled microdisplay is achieving higher usable brightness for AR optics (which often lose light through waveguides and lenses). Tandem OLED stacks are one approach widely discussed to improve brightness and efficiency in microdisplays. BOE has publicly emphasized tandem-related progress and high-performance microdisplay demonstrations in its recent OLED microdisplay developments.4、Applications: Where a 4K Micro OLED Microdisplay Fits Best
A high-PPI micro oled is most commonly positioned for:AR/VR headsets and near-eye viewfinders (ar vr display, xr display)
Compact optical modules where size and clarity matter
Professional and industrial visual systems requiring small, sharp displays
BOE continues to promote a broader VR/AR microdisplay portfolio and XR solution direction, indicating ongoing expansion of microdisplay productization and application coverage.

5、Market Outlook
Micro-OLED / oled microdisplay demand is widely associated with AR/VR device growth.Currently, BOE (Beijing BOE) has put 8-inch and 12-inch Micro OLED production lines into operation and has developed multiple high-resolution products ranging from 0.39 to 1.3 inches. Its Micro OLED products for VR and AR applications are now ready for shipment, and certain sizes—such as 0.49 inch and 0.71 inch—have already entered mass production and are being delivered.Public market summaries show the Micro-OLED display market at ~USD 1.33B in 2023 with continued growth expected.
