NEC NL204153AC21-09 Specifications:

NEC: On January 2, 2008 NEC Electronics America, Inc. introduced two new 21.3″ TFT LCD modules intended for medical imaging applications. These two modules are the first to incorporate NEC LCD Technologies’ ultra-advanced, super-fine TFT (UA-SFT) display technology in a 21.3″ LCD. The UA-SFT technology improves light transmittance by 20% allowing for brighter displays with the same backlight. In addition, the 21.3″ medical panels use a high-intensity direct-backlight system for improved brightness. Samples are available now and pricing can be acquired via NEC Electronics America.
The 1600×1200 pixel format does not seem to be high-density enough for x-ray or MRI applications that require extreme fine detail. The 2048 x 1536, however, should be quite a bit more adequate. When little spots can mean the difference in the health industry, I would hope that there are absolutely zero pixel and sub-pixel defects on 100% of these panels.
