Sony announced their 0.5" XGA (1024x768) OLED microdisplay - as used in four new cameras. It turns out that Sony is producing this OLED display on their own. The cameras that use this displays are the A77 and A65 DSLRs and the NEX-7 and NEX-5N mirrorless interchangeable-lens cameras (the NEX-5N doesn't come with the viewfinder, but you'll be able to buy it for $350).
To create those small pixels, Sony used a new design that uses white OLEDs and color filters. Sony also uses in-built D/A converters and driver electronics to create a small footprint.
Those four cameras aren't shipping yet, but according to Engadget the OLED display is terrific: "...the camera's OLED viewfinder is the star of the show... bright and vibrant..."
We heard about this OLED microdisplay viewfinder a long time ago - and recently we heard rumors that it was actually made by Samsung. But now it's official - this is a Sony made product.
