Optrex Intros First Hi Contrast LCD
Hi-contrast LCD display.
Plymouth, MI — Optrex Corp. (Tokyo) and Optrex America, Inc. have introduced the first passive matrix LCD with Advanced Black Nematic (ABN) technology. LCDs with ABN technology provide higher contrast ratios and wider viewing angles than conventional passive matrix displays, with true black levels, no performance shift over wide temperature ranges, and virtually no color shift.

Conventional passive matrix displays offer limited performance, such as brightness of less than 100cd/m2 and contrast ratio of less than 80:1, which are not acceptable for some applications. As a result, Vacuum Florescent Display (VFD) technology has been prevalent in many automotive and certain industrial applications. However, LCDs utilizing ABN technology can achieve performance equal to or better than VFD. They provide a true black level by dramatically reducing the light leakage, resulting in contrast ratios of up to 1000:1, super wide viewing angles, and no performance shift over a wide temperature range. Because LCDs with ABN technology exhibit practically no color shift, any backlight color can be used without compromising the contrast ratio. ABN was originally developed by the company for custom modules used in automotive applications. Its first standard passive LCD with ABN technology, the C-55605GNFU-LW-AAN, is a 20 x 2 character display with 600cd/m2 brightness, a contrast ratio of 550:1, and standard 8-bit parallel interface. According to the company, this is the first time that a passive matrix monochrome display has offered such a high level of performance.
