NEC LCD Technologies’ New 21.3-Inch Monochrome LCD
for Medical Use Achieves Industry’s Highest Resolution
For immediate use October 17, 2006
NEC LCD Technologies, Ltd.
Tokyo, October 17, 2006 --- NEC LCD Technologies, Ltd. today announced the development of a new monochrome, 21.3-inch (54-centimeters-diagonal) amorphous silicon thin film transistor (TFT) liquid crystal display (LCD) module. Boasting the industry’s highest resolution in the category of monochrome LCDs for medical use, this LCD is ideal for diagnosis of radiogram interpretation, in particular, digital mammography images.
The new LCD module is being positioned as a top-end product in the company’s monochrome LCD module lineup and commercial production is targeted for the middle of 2007. Its resolution of 2800 x 2100 pixels (approx 6 mega-pixels) surpasses that of NEC LCD Technologies’ high-end module NL256204AM15-01/01A, which has a resolution of 2560 x 2048 pixels.
Furthermore, each pixel of this monochrome LCD module consists of three sub-pixels, and a 10-bit TFT LCD source driver enables individual sub-pixel control of 1024 grey-scales from input to output. This realizes simultaneous display of 3070 grey-scales (equivalent to 11.5 bits) per pixel, without the need for any interpolation technologies such as frame rate control (FRC). As a result, the new LCD boasts extremely high quality, making it appropriate for radiographic image diagnosis with mammography, which requires a high density and high level of grey-scale quality.
The main characteristics of the new model are as follows:
- Industry’s Highest Resolution
The new LCD boasts the industry’s highest resolution in the category of monochrome LCDs at 2800 x 2100 pixels (approx 6 mega-pixels) enabling 12% greater display of screen information than NL256204AM15-01/01A. - High Level of Grey-Scale Quality
Each pixel of the LCD consists of three sub-pixels, and a 10-bit TFT LCD source driver enables individual sub-pixel control of 1024 grey-scales from input to output, realizing simultaneous display of 3070 grey-scales (equivalent to 11.5 bits) per pixel, without the need for any interpolation technologies, such as frame rate control (FRC). - High Luminance, High Contrast Performance and Wide Viewing Angle
Further refinement of NEC LCD Technologies' own unique super-advanced, super-fine TFT (SA-SFT) technology combined with panel design optimization achieve luminance of 1000cd/m2 and a contrast ratio of 1000:1, the highest levels in the 5 mega-pixel and above monochrome class. In addition, the new module boasts superior control of viewing angle dependence of grey-scale and contrast performance, achieving steady screen quality even in multi-screen environments. - Size Compatibility
Compatibility with NEC LCD Technologies’ existing 2 and 3 mega-pixel monochrome modules is achieved by an aspect ratio of 4:3 and its 21.3-inch (54cm) diagonal size. This enables sharing of molding die with LCD monitors that adopt NEC LCD Technologies’ 2 and/or 3 mega-pixel LCDs, contributing to shortened product development periods and a reduction in development cost for LCD monitor manufacturers.
Recently, there has been a trend toward digitalization of medical equipment such as electronic medical chart systems and picture archiving and communication systems (PACS). Monitors used for interpretation of radiogram diagnosis, which have replaced the film business, require far higher picture quality than that of general IT monitors for accurate screen reproduction of image information obtained from various modalities. In particular, extremely high picture quality in resolution, grey-scale performance, dynamic range and screen uniformity is required for diagnostic imaging of digital mammography in order to accurately distinguish microscopic calcification, an initial symptom of breast cancer.
"Our new 21.3-inch LCD fills an important gap in the market for medical monitors. Not only does it offer the industry’s highest resolution providing the best display environment for diagnostic imaging of digital mammography, it also offers great benefits to monitor manufacturers in terms of reduced development costs and shortened product development cycles," said Masaaki Hiroshima, department manager in charge of product planning and marketing, NEC LCD Technologies, Ltd.
NEC LCD Technologies will continue to pursue an even higher level of picture quality to supply products unrivaled in the medical field. This new product will be displayed at FPD International 2006, which is being held in Pacifico Yokohama, Japan, from October 18 - 20.
