Sony unveiled a new 20.5" monochrome OLED monitor for the medical industry. This monitor offers 2048x2560 resolution, high luminance, wide viewing angle, high contrast and deep, rich black reproduction (the black level is less than 0.001cd/M2 and 500 cd/M2 luminance). The monitor isn't available yet, and apparently it doesn't have a model number yet.
Sony is already offering the full-color 25" Trimaster EL PVM-2551MD medical monitor, which has recently received FDA approval for use in surgery (the first OLED panel to do so). It costs €6,000 (which is 50% more expensive than the equivalent LCD monitor from Sony).
A couple of months ago Sony announced that they already sold over 15,000 professional OLED monitors. When we discussed OLEDs with Sony's OLED product manager back in February 2012 he said that the OLED fab at Nagoya Japan is running at full capacity.
