Tokyo, October 18, 2005 --- NEC LCD Technologies, Ltd. today announced the successful development of 10.4-inch (26cm diagonal), amorphous silicon thin-film-transistor (TFT) liquid crystal display (LCD) modules with the world's fastest Motion Picture Response Time (MPRT), a standard promoted by the Video Electronics Standards Association (VESA). Both new models realize the industry's highest motion picture performance.
Outline of the two new models:
- XGA TFT LCD with wide viewing angle for broadcasting and medical use
This new XGA TFT LCD boasting the world's fastest MPRT of 6.0msec and the industry's highest motion picture performance was enabled by the following:
- Doubling of the response speed of conventional SFT LCDs through optimization of the LCD design, comprising of a change in liquid crystal material and revision of the cell structure, based on NEC LCD Technologies' proprietary super-advanced, super-fine TFT (SA-SFT) technology.
- Adoption of a blinking-backlight approach to improve motion picture blurring caused by hold-type displays, which are typical to LCDs. - Standard VGA TFT LCD for industrial applications
This new VGA TFT LCD boasting the world's fastest MPRT of 5.0msec and the industry's highest motion picture performance was enabled by the following:
- Acceleration of the response speed through optimization of the LCD design, comprising of a change in liquid crystal material and revision of the cell structure, based on a twisted nematic (TN) mode, currently the most standard driving method.
- Employment of an over-drive circuit to improve the gray-to-gray response speed, which has been an issue with TN-mode LCDs to date. In addition, adoption of a blinking-backlight approach to improve motion picture blurring caused by hold-type displays, which are typical to LCDs, and 120Hz driving, which is double the speed of the usual frame rate, simultaneously.
Recently, the market has seen a rapid increase in the use of LCDs in PC monitors and TVs, which has brought with it a rise in demands from not only these fields but also other target fields of NEC LCD Technologies including broadcasting, medical, measuring instruments and factory automation. However, issues effecting motion picture performance still remain such as the slowness of the response speed of the liquid crystal itself and the afterimage phenomenon caused by hold-type displays and the characteristics of human vision.
"We chose to develop a 10.4-inch LCD as this is the largest scale required in most industrial fields, and we have every confidence that the dramatic improvement in motion picture performance in both our new XGA and VGA models will guarantee its rapid penetration in the marketplace" said Hidetoshi Usui, department manager in charge of product planning and marketing, NEC LCD Technologies, Ltd.
NEC LCD Technologies' leading-edge technology and specialized know-how have earned it a leading position in the market and it will strive to further advance and develop a range of high value-added products to meet the various demands of its customers worldwide.
Both new models will be displayed at FPD International 2005 being held in Pacifico Yokohama, Japan, from October 19 - 21.
