Sony unveils 0.44-inch OLED microdisplays for AR glasses

Sony Semiconductor Solutions officially announced the ECX350F, a 0.44-inch OLED microdisplay designed for AR (augmented reality) glasses, on the 24th.

Compared to its predecessor, the ECX348E, the ECX350F has been significantly optimized in terms of pixel size, which has been finely reduced from 6.3 microns (0.0063mm) to 5.1 microns (0.0051mm). Its screen refresh rate is up to 120 frames per second and it perfectly covers the sRGB color gamut to 100% display standard. With its innovative light-emitting structure and micro-lens technology, the display not only achieves Full HD (1920 x 1080 pixels) resolution, but also doubles the maximum brightness of its predecessor to 10,000 candela per square meter (cd/m^2).

In addition, through carefully designed internal circuit wiring optimization, the ECX350F has successfully reduced the thickness of the bezel surrounding the OLED panel to 1.14 mm at the top and bottom, which is significant in reducing the overall thickness and weight of the AR glasses.

It is worth mentioning that the ECX350F also adds a variable black frame feature, which allows displaying videos with less than Full HD resolution anywhere within the panel. This processing is done by the display unit itself on the AR glasses, rather than relying on the SoC, effectively reducing latency and power consumption.

Sony Semiconductor Solutions said the launch of the ECX350F is designed to bring users a better AR experience by reducing the size and weight of the AR glasses while providing higher resolution and sharper images.
