Sony announces their 0.5" XGA OLED microdisplay and four cameras that use it as viewfinder
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.
