Sony launches a new 10,000 nits 0.44-inch FHD OLED microdisplay - the world's brightest and with the smallest pixels

Sony announced a new OLED Microdisplay, the ECX350F, a 0.44" 120Hz 1920x1080 (FHD) microdisplay that offers the world's highest brightness at 10,000 nits. It also offers the world's smallest pixel size at 5.1 um (the PPI is around 5,000).

Sony says that in order to reach this high brightness, it adopted a new OLED stack structure, a new "semiconductor process" and added a microlens array on top of the display. In addition, the bezel size of the new display is exceptionally small, with only 1.14 mm of added bezel on the long side of the display on both top and bottom.

Apple looks to adopt a TFT AMOLED for its future entry-level MR headset

There's an interesting report in Korea that claims that Apple is developing an entry-level MR headset, and is looking to adopt TFT based AMOLED displays, as opposed to the currently-used OLED microdisplays. It is reported that both JDI and Samsung are in talks with Apple, and have been requested to develop lower-cost TFT AMOLEDs with a pixel density of 1,500 PPI (down from 3,400 PPI high-end Sony microdisplays used in the Vision Pro).

Apple Vision Pro

It is understood that JDI has already developed the technology and produced 1,500 PPI samples for Apple. Interestingly it is reported that the JDI displays uses Sony's technology, although it is not stated which technology exactly. Samsung meanwhile is also developing 1,500 PPI AMOLEDs at its A2 fab. Apple's target is to release the headset at around 2026-2027 and by then it is likely that more OLED producers (such as LG Display) will develop similar displays.

BOE developed 5,000 nits tandem 4K 0.9" OLED microdisplays

During the company's 2024 Innovation Partner Conference, BOE unveiled its latest OLED microdisplay. The display is a 0.9" 4K (6020 PPI) panel, that is based on a tandem OLED architecture. It achieves a maximum brightness of 5,000 nits.

BOE has also unveiled ultra-light (150 grams) VR glasses based on these displays. It is not clear whether this is a product that BOE aims to commercialize, or a reference design, or a product produced by one of its partners.

Apple announces its 2024 iPhone 16 series, and the new Apple Watch Series 10, all with AMOLED displays

Yesterday Apple announced its 2024 iPhone 16 series, and its latest smartwatch devices - all based on OLED displays. We'll start with the the iPhone 16 that offers a 6.1" 2,000 nits (HBM) 1179x2556 Super Retina XDR LTPS AMOLED, while the iPhone 16 Plus offers a larger 6.7" 1290x2796 display. Both phones are based on Apple's latest 3nm A18 chipset offering improved performance and AI support.

The iPhone 16 Pro has a more advanced 6.3" 120Hz 2,000 nits (HBM) 1206x2622 LTPO Super Retina XDR OLED. The 16 Pro Max offers a larger 6.9" 1320x2868 AMOLED. These new phones are based on Apple's 3 nm A18 Pro chip, offer a "huge leap in battery life", support Apple Intelligence and feature new a main camera.

Researchers achieve OLED displays boasting 84,000 PPI, with the world's smallest OLED pixels

Researchers from ETH Zürich and the Huazhong University of Science and Technology developed a new scalable fabrication technology that enables the deposition of extremely small OLED pixels. The so-called nano-OLEDs achieve a pixel density of 84,000 PPI, or even higher. The pixel size is around 100 nm, the smallest pixels ever reported.

The method is based on direct nanomolecular patterning of the OLED materials, realized by self-aligned evaporation through nanoapertures fabricated on a free-standing silicon nitride film adhering to the substrate. The researchers report that the average nano-OLED EQEs is up to 10%.

Researchers develop a new method to produce 20,000 PPI OLED microdisplays

Researchers from Soochow University and the University of Muenster have developed a method to produce ultra high resolution OLED microdisplays - with up to 20,000 PPI.

To achieve such high resolution, the researchers used a method they refer to as "first surface patterning and then patterned growth". The idea is that the substrate is first patterned using lithography, and then the organic materials are deposited. Following the substrate treatment, the organic materials are diffusing on the substrate, selectively grown on the designated areas.

Visionox shows its latest OLED and MicroLEDs at Displayweek 2024

During Displayweek 2024, Visionox demonstrated many OLED display technologies and panels, and also an interesting microLED prototypes (produced by its subsidiarity Vistar).

Visionox is in the final stages of development of its ViP maskless display production process, and the company showcased some nice ViP smartphone panel prototypes (the technology can be used for any panel size). ViP offers a high improvement in aperture ratio (69% up from 29%) which results in low power consumption and brightness (up to 4X according to Visionox), improved lifetime (up to 6X), improved PPI and more.

LG Display shows its latest OLED displays at Displayweek 2024

LG Display demonstrated its latest OLED display prototypes and commercial panels at Displayweek 2024. The company showed flexible panels, automotive displays, transparent OLED, gaming monitors, a 10k nit microdisplay and more.

So first up, LG Display shows its automotive Advanced-Thin-OLED (ATO) displays, which are produced on glass substrates and use a tandem structure. These OLEDs are lower in cost compared to LGD's flexible automotive p-OLED panels, but still enable low-weight and thin profile, and the excellent image quality of an OLED display. The smaller display was a 12.3" 2400x900 (209 PPI) 1,000 nits panel, while the other panel was larger at 17" 1920x2560 (188 PPI).
