NEC Electronics America Inc. introduced two new color, 21.3-inch diagonal amorphous-silicon thin-film transistor (TFT) liquid-crystal display (LCD) modules for medical imaging applications.
The new display modules represent the first application of NEC LCD Technologies’ advanced, super-fine TFT (UA-SFT) display technology in a 21.3-inch LCD. Combined with NEC LCD Technologies’ newly designed high-intensity direct-backlight system, the modules achieve very high luminance levels, high contrast ratios, high brightness uniformity and ultrawide viewing angles.
The new LCD modules deliver high luminance levels for their respective resolutions. The NL160120AC27-20 module features
ultra-extended graphics array (UXGA) resolution and a brightness level of 950 candelas, while the NL204153AC21-09 module has higher-density quad-extended graphics array (QXGA) resolution and a brightness level of 800 candelas.
With UA-SFT technology, the new modules achieve 20 percent improvement in light transmittance compared to modules based on super-advanced, super-fine TFT (SA-SFT) technology. Both modules also support monochrome image interpretation as a result of their precise reproduction of grayscale images.
