High-contrast mono LCDs available with colour filters
A range of high-contrast mono LCDs, which are optionally available with colour filters, has been released by Varitronix. The displays use Improved Black Nematic (IBN) technology to provide a high contrast ratio of around 1000:1 with low bleed-through of light around the edges of the ON segment characters and graphics.
Colour filters can be customer-specified to provide areas of bright, coloured characters on a black background. As an alternative option to colour filters, tri-colour backlights can be specified to highlight the display status with differing colours.
IBN technology offers a stable optical performance and wide viewing cone over a typical operating temperature range of -30 to +85°C and typical drive conditions of 1/9 duty, 1/4 bias. The IBN technology is already widely used within the automotive sector for dashboard and HVAC applications where clarity of information over a wide viewing cone is paramount.
The high-contrast mono LCDs are manufactured in accordance with international certifications, including ISO 9001 for general quality management and ISO/TS 16949 for quality management of automotive products. Suitable markets include automotive, industrial, commercial and medical.
