Sony announces the world's smallest pixel pitch OLED microdisplay

Sony launched a new OLED microdisplay, the ECX339A, which has the world's smallest pixel pitch (according to Sony) at 6.3um. The 0.5-inch microdisplay's resolution is 1600x1200 (UXGA) and it supports a frame rate of up to 240 fps. The maximum brightness is 1,000 nits.

Sony already started sampling this new microdisplay in January 2018, and mass production is planned for November 2018. The price of each sample is ¥50,000 - or about $460 USD.

The new microdisplay uses a new drive circuit design, that operates at half the voltage of Sony's previous microdisplays. The new microdisplay features the same power consumption of Sony's older generation 0.5" display even though the resolution is much higher. In this new display Sony also updated the production process and it now deposits the color filters directly on the silicon substrates - which results in larger viewing angles.
