Varitronix has extended its range of high contrast IBN displays with the addition of a range of character modules based on this technology, in sizes from 1x8 characters to 4x40.

The IBN (Improved Black Nematic) displays offer a contrast ratio of 500:1, as well as a wide viewing angle of -35 degrees to 35 degrees horizontally and vertically, a wide temperature range of -35 to +80 deg C.

IBN technology works along similar principles as standard twisted nematic (TN). However, the liquid crystal molecules are vertically aligned, as opposed to horizontally, allowing a very pronounced black in negative mode. 

The new range of modules not only increases the variety of characters and graphics that can be presented on the displays, but also adds the option of colour filters to offer the opportunity to show different colour characters.

They are likely to be suitable for automotive and industrial applications where high contrast ratios and wide viewing angle displays are required to present segmented characters or pictograms.
