NEC Expands Lineup of Displays for Medical Imaging with Two New 21.3-Inch LCD Modules

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 ultra-wide 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 a 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.

The company says enhanced panel design combined with UA-SFT technology help prevent light leakage and image and color distortion, thereby improving viewability of the display from almost any angle. As a result, the NL160120AC27-20 and NL204153AC21-09 modules achieve high contrast ratios of 800:1 and 750:1, respectively. The panel design also inhibits the "washed-out black" phenomenon that occurs when the viewing angle is enlarged.
