Optrex Corp. is bringing its Advanced Black Nematic (ABN) technology to passive matrix LCD displays, saying it offers true black levels, higher contrast ratios, and wider viewing angles than conventional passive matrix displays, among other benefits.

"The passive matrix monochrome LCD market remains a significant focus for Optrex," Optrex America president & CEO Cynthia Ferrell said. "While some LCD manufacturers have decided to exit the passive LCD market, Optrex continues to support it with new developments such as Advanced Black Nematic technology."

The company said in a statement that LCDs utilizing ABN technology can perform as well as or even better than those using Vacuum Florescent Display (VFD) technology, which are prevalent in automotive and some industrial applications. ABN, developed by Optrex for custom modules in automotive applications, offers true blacks, contrast ratios of up to 1000:1, super wide viewing angles, and no performance shift over a wide temperature range. Also, manufacturers can use any backlight color without compromising the contrast ratio because there is practically no color shift.

Optrex's first standard passive LCD with ABN technology is the C-55605GNFU-LW-AAN, a 20x2 character display with 600 cd/m2 brightness, a contrast ratio of 550:1, and standard 8-bit parallel interface.
