NEC Electronics America Inc. announced two 21.3-inch amorphous-silicon TFT LCD modules from NEC LCD Technologies Ltd. These include the NL280210AM15-01A and NL160120AM27-13A monochrome LCD modules for medical applications.

The six-million-pixel monochrome LCD module, part number NL280210AM15-01A, features a resolution of 2800 x 2100 pixels, which is said to be among the highest resolutions available in a monochrome LCD module for medical use, making it suitable for use in high-resolution radiographic image applications.

The NL280210AM15-01A LCD module can display approximately 12 percent more screen information than NEC's five-million-pixel monochrome display modules, the NL256204AM15-01 and NL256204AM15-01A. In addition, the module's 10-bit TFT-LCD source driver enables individual sub-pixel control of 1024 grayscales for excellent grayscale quality. This means the module can display 3070 grayscales (11.5 bits) per pixel simultaneously without the need for interpolation technologies such as frame rate control (FRC), according to the company.

Offering a wide viewing angle, the NL280210AM15-01A LCD module offers an aspect ratio of 4:3, high luminance of 1,000cd/m?, and high contrast of 1000:1. With an aspect ratio of 4:3 and its 21.3-inch diagonal size, the module is compatible with NEC LCD Technologies' existing two- and 3Mpixel monochrome modules, which enables sharing of monitor enclosures with LCD monitors that adopt NEC's two- and/or 3Mpixel LCDs.

The NL160120AM27-13A two-million-pixel monochrome LCD module offers an ultra-extended graphics array (UXGA) resolution and a luminance level of 1,700cd/m?, which is said to be one of the highest luminance levels of any monochrome UXGA or higher-resolution LCD module currently available. The combination of NEC's super-advanced, super-fine TFT (SA-SFT) technology and a high-intensity direct backlight system enables the NL160120AM27-13A to achieve this luminance level, said the company.

Suitable for use in X-ray image applications, the NL160120AM27-13A module offers a high contrast ratio of 850:1 and uniform high brightness over the entire screen. An optimized optical design inhibits the "washed-out black" phenomenon that occurs when a viewing angle is enlarged, which is a common issue with in-plane switching (IPS)-type LCD modules, and results in enhanced contrast ratio over wider viewing angles, said the company.
