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 100 cd/m2 and contrast ratio of less than 80:1, which are not acceptable for some applications. 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.
