NEC LCD Technologies, together with its sales and marketing channels in the Americas and Europe, NEC Electronics America and NEC Electronics (Europe) GmbH, introduced a new 22.5-inch amorphous-silicon TFT LCD module, with WUXGA resolution. The new module boasts excellent picture quality, ideal for preview monitoring and verification use in broadcast stations and post-production studios, thanks to full high-definition (1920x1080) resolution, high luminance of 460 cd/m2, a wide color gamut of 97% (NTSC ratio) and a double frame rate of 120 Hertz to improve motion picture performance.

The main characteristics of the module are as follows.

  • High level of color reproducibility

    NEC LCD Technologies’ proprietary ultra-advanced, super-fine TFT (UA-SFT) technology boasting high transmissivity achieves high luminance of 460 cd/m2 and a wide color gamut of 97% (NTSC ratio). In addition, a 10-bit source driver enables the module to provide 1024 grayscale steps per each of the primary colors (RGB), thus realizing 1073 million colors per pixel. The module attains a higher color resolution than specified by the European Broadcasting Union (EBU) standard, the de-facto standard for broadcast applications, and hence produces higher-quality images.
  • Support for improvement of motion picture performance

    Using a double frame rate of 120 Hz, the LCD module can be used by customers in equipment such as high-performance motion picture monitors to improve motion picture performance using black frame rate insertion, or interframe interpolation.
  • Ultra-wide viewing angle

    UA-SFT technology also enables an ultra-wide viewing angle of 176 degrees and reduces the color shift problem that occurs due to a change in viewing angle. Allowing greater flexibility in terms of display placement and viewing position, the module is also suitable for multi-screen use.

“The introduction of the new 22.5-inch high-definition LCD is further evidence of NEC LCD Technologies’ longstanding dedication to providing advanced display solutions that meet the sophisticated requirements for high-end monitor applications such as high-performance motion picture monitors,” said Hidetoshi Usui, department manager in charge of product planning and marketing, NEC LCD Technologies, Ltd. “

In addition to the new 22.5-inch LCD module, NEC LCD Technologies also offers a new 19.0-inch color TFT LCD module, part number NL128102BC29-10, with super-extended graphics array (SXGA) resolution. Both products will be displayed at Display 2008, April 16–18 at Tokyo Big Sight, Japan, and SID 2008, May 20–22 at the Los Angeles Convention Center, USA.
