OLED displays are excellent for driving AR glasses and devices - as they provide high quality images, low power consumption and high brightness (although not as high as MicroLED displays).

Are you looking for an OLED microdisplay for your new project? We have access to a wide range of options, check out the OLED Marketplace for more.

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).

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.

Samsung shows a 1.3" 12,000 nits OLED microdisplay at K-Display 2024

Samsung Display demonstrated a new OLED microdisplay at K-Display 2024, a 1.3" 12,000 nits 4000 PPI display. It is not clear whether this display is a direct-emission display, or one that uses white OLEDs with color filters.

Samsung Display's CEO, Choi Joo-seon, said during the conference that SDC will soon commercialize OLED microdisplays based on eMagin's direct-patterning deposition technology (SDC acquired eMagin in 2023). Choi says that the price of OLED microdisplays is an important differentiating factor. Last week Omdia estimated that the price of OLED microdisplays is set to decline sharply in the near future.

Microsoft agreed to order a few hundreds of thousands of units of Samsung's OLED microdisplays. Samsung Display is collaborating with Samsung System LSI, that will design the CMOS backplane, which will be produced by Samsung Foundry. Samsung Display will handle the frontplane OLED deposition and encapsulation.

Lumicore Showcases High-End Digital-Driven Silicon OLED Microdisplays

Lumicore showcased its groundbreaking 1.32-inch OLED microdisplay at SID Displayweek in San Jose, a digital-driven silicon microdisplay that represents a substantial advancement in the field of micro-OLED displays. This innovation promises improvements in display quality, power consumption, and production yield, making it highly suitable for AR and VR/MR applications.

Lumicore's expertise lies in its digital driving technology, which precisely controls pixel brightness in Micro-OLEDs through Pulse Width Modulation (PWM). This approach maintains a constant voltage across the OLED, preventing substantial fluctuations in current and brightness due to minor voltage changes.Compared to traditional analog driving, digital driving effectively mitigates noise interference, offering higher grayscale modulation accuracy, faster screen refresh rates, lower circuit power consumption, and reduced manufacturing costs, thereby revolutionizing the conventional technology.

First impressions from SID Displayweek 2024

The display industry's premier event, Displayweek, is over. We will now collect our notes, thoughts, photos and images and will share it all in the coming days. In the meantime, we'd like to detail some initial impressions.

Generally speaking, it seems as if the display industry is going through a phase of relatively little innovation, especially with the mature LCD and OLED industry segments. While it has been a very busy week, and attendance at the event seems high, the number of actual demonstrations and prototypes was not stellar and compared to previous years, the booths were smaller and some companies skipped the event this year or preferred to only show their latest displays in private settings. Some thoughts we have:

Samsung said to adopt Sony OLED microdisplays in its upcoming VR headset

Samsung Electronics is developing a new high-end VR headset, likely aiming to release it by the end of 2024. According to reports, Samsung will integrate OLED microdisplays produced by Sony, similar 1.4" 4K displays that are used by Apple in its Vision Pro headset.

Samsung Display is developing its own OLED microdisplays, and the company is looking to bring such displays to market soon - in fact initial production will begin by the end of 2024, and full mass production will be achieved in 2026. It is not clear whether this new Sony design win means that Samsung Electronics prefers the Sony displays over SDC's, or whether it's simply a matter of Samsung Display not ready in time for mass production.

Seeya starts constructing its second OLED microdisplay production line in Shanghai

OLED microdisplay developer Seeya Technology announced that it is starting to build its second OLED microdisplay production line, in Shanghai. The company will start to move in and install the production equipment next month.

The new production line will have a monthly capacity of 9,000 300 mm substrates, similar to the company's first line which is already in mass production. The total cost of the new fab is expected to reach 2 billion Yuan (around $275 million USD).

Lakeside Lightning Semiconductor progresses with its 12-inch OLED microdisplay production line

China-based OLED microdisplay developer Lakeside Optoelectronics (also known as Lakeside Lightning Semiconductor) announced that it is progressing with its 12-inch OLED microdisplay production line project in Yixing (Wuxi). The building itself is nearly complete, with the last floor concrete poured in. 

The new fab will have a capacity of 7,000 monthly 12-inch substrates, and should enter production in October 2025. The company also plans a 2nd phase which will double its capacity and enable it to produce around 10 million OLED microdisplays per year.
