Sony Semiconductor Solutions to Release 0.44-Type Full HD OLED Microdisplay

Sony Semiconductor Solutions Corporation (SSS) today announced the upcoming release of the ECX350F, a 0.44-type Full HD resolution OLED Microdisplay that combines the industry's smallest 5.1 µm pixels (approximately 5,000 ppi) with the industry's highest brightness of up to 10,000 cd/m².

The ECX350F is an OLED Microdisplay designed for use in augmented reality (AR) glasses, an application which demands a thin, lightweight form factor without compromising visibility. Adopting a novel OLED structure and microlenses, the microdisplay enhances pixel light emission despite its diminutive size. This innovation allows for Full HD resolution within a compact 0.44-inch panel while delivering a peak brightness of 10,000 cd/m² — approximately double that of the conventional model. This new product represents a breakthrough that addresses the longstanding challenge of delivering high brightness with small pixels.
Beyond reducing the size and weight of AR glasses, SSS is committed to enhancing the user experience by supporting high-resolution, exceptionally clear imaging.

Main Features

Industry-smallest 5.1 µm pixels and highest brightness of up to 10,000 cd/m²
  • Shrinking OLED Microdisplay pixels typically reduces luminous efficiency and limits per-pixel current, hindering the attainment of high brightness.
  • The new microdisplay product addresses these challenges thanks to a newly developed semiconductor process for fabricating 5.1 µm pixels and microlenses that optimize luminous efficiency at this scale. Additionally, a uniquely designed OLED structure strikes the ideal balance between driving voltage and luminous efficiency, delivering both high brightness and small pixels.
  • Consequently, the ECX350F delivers Full HD resolution with the industry-smallest 5.1 µm pixels and exceptional visibility with industry-leading brightness of up to 10,000 cd/m².
Miniaturization through smaller pixels and narrow bezels
  • The non-display area (bezel) surrounding the active display area integrates the circuits and wiring required for the display drive. With conventional technology, it was difficult to narrow the bezel due to concerns about reliability as a display device and issues such as poor screen display caused by the required wiring width of the circuit portion. The new product solves these problems by introducing a new circuit design and assembly process, reducing the bezel size on the long side of the display to 1.14 mm on both the top and bottom.
  • By miniaturizing the pixels and narrowing the display bezel, the new microdisplay boasts a short-side size of 7.99 mm, a 24% reduction from the conventional product, while maintaining the pixel count needed for Full HD, thereby enabling AR glasses to be made thinner and lighter.
Variable black frame function supporting variable input resolution and display position
  • The new product comes with a variable black frame function that enables it to display video input of any resolution below Full HD at any desired position within the device's active display area.
  • Generally, in AR glasses, the real space is visible through the black display area, allowing the displayed image to be overlaid on the real space. This function was achieved in the conventional product by generating a video signal for the black display area in the pre-processing side (application processor) and inputting it. However, with the microdisplay device now itself performing this process, it is easy to display images at an arbitrarily set resolution, and this also contributes to low power consumption and low latency for the system.

AR in 2024 in like Internet in 1970.
This will change our life like Internet for ever.

How is this different than the OLED viewfinder on the Sony A1 or A9III? I mean that optical viewfinder is 9.44Mdot (2048 x 1536px) so technically this product is less resolution???

I use the Sony A7RIII which has a 3.69M-dot (1280 x 960 pixel) OLED viewfinder and its pretty trash resolution when looking through it...better than the screen but definitely nothing worth for AR or 3d goggles.
Pretty sure it can also do 120hz but at a slightly reduced resolution which is likely either the interface or processing power so I'd imagine they could easily get 120hz at 1440p.

Those are some impressive specs. The board with a connector is bigger, which in itself is amazing.

Is this impressive? Some digital cameras are using EVF's with 9.44Md or 3.15MP ~ 2200 x 1400 that are OLED and HDR.
