Optrex Passive Monochrome LCDs with Advanced Black Numatic Technology
Originally developed by Optrex as one of it technological innovations for the American automotive market, Advanced Black Numatic (ABN) achieves a true black level by dramatically reducing the light leakage, resulting in exceptional performance for a passive monochrome display.
ABN technology uses a special liquid crystal alignment structure to achieve a true black level, it dramatically reduces the light leakage to 0.008%. The LCD panel features contrast ratio of 1000:1(for segment type), super wide viewing angle, and with no performance shift over wide temperature range.
This technology also exhibits practically no color shift, so any backlight color can be used without compromising contrast ratio.
