TOKYO, June 24, 2008 - Casio Computer Co., Ltd., announced today that it has developed a new transmissive liquid crystal display module intended for commercial use in handheld terminals and similar devices. The new "Blanview LCD" module, samples of which will be shipped commencing July 2008, offers both lower power consumption and superior visibility regardless of where it is used - indoors or out. Transmissive LCDs have been adopted for displays in a wide variety of devices, thanks to their excellent ability to reproduce color and their superb visibility. Until now, however, the power consumption for the backlight needed to offer a light source intense enough to compete with bright outdoor light has been quite high. Batteries would run out too quickly. The conventional solution for commercial handheld devices frequently used outdoors has been to use semi-transmissive LCDs, which do not require a backlight outdoors. Because of their construction, however, with each pixel part transmissive and part reflective, semi-transmissive LCDs are not able to offer as clear a display image as transmissive LCDs, and the percent of light transmitted is low. This means that, when used indoors, the backlight has to be even brighter, which drives power consumption even higher. But users need displays that work indoors and out, without running out of batteries all the time. Casio has found an outstanding solution for reducing power consumption without sacrificing visibility. The new Blanview LCD achieves a pure white screen by optimizing color balance, and boasts a light transmission factor about 30% higher than conventional units. Thanks to these breakthroughs, characters and icons clearly display on a pure white screen, without using very much power. The power consumption of the backlight has been kept to about half that required by the transmissive LCDs currently used indoors, and about 1/3 that needed by the semi-transmissive LCDs commonly used today. In addition, Casio found a way to make the LCD panel take in external light efficiently, eliminating the need for a backlight when outdoors while still delivering a clear display with excellent visibility in broad daylight. All of these innovations combine to make the Blanview LCD the best choice of display for commercial handheld devices used for extended periods of time indoors and out.

The product name, Blanview, was derived from a combination of the French "blanc," meaning white, and the English "view." Blanview is a trademark of CASIO COMPUTER CO., LTD.
