Monochrome TFT is high-performance alternative
Transflective mono TFT unit delivers better sunlight readability and maintains a greater contrast ratio in sunlight than a transmissive unit.
This makes them ideal for signage, labelling and status indicators where information is presented for long periods without updating.
The new frontlight system uses white LEDs and a special light guide to provide the maximum efficient illumination with minimal power consumption.
A strength of Varitronix BCD technology is its excellent visibility.
Far from degrading under bright light, display contrast actually increases in direct sunlight.
Thanks to the absence of polarisers in this technology, viewing angles of up to nearly 180 degrees are achievable.
The new frontlight option means that the displays can now also be used at night, opening up a wider range of possible applications.
Varitronix is offering standard BCD displays in resolutions from 32 x 32 to 240 x 160 and 478 x 638 pixel, although displays are customisable depending on project requirements.
Varitronix's BCDs are available in a range of attractive monochrome colour combinations, including blue/white, red/amber, yellow/green, pink/peach and orange/yellow.
