Bi-stable Cholesteric Display (BCD) range frontlight option
13 May 2008
Varitronix has released a frontlight option to its Bi-stable Cholesteric Display (BCD) range making the displays suitable for use in low light environments.
Varitronix BCDs are non-volatile and will retain their image contents for periods of up to 10 years with no power source, only requiring power when information on the screen is changed. 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.
Varitronix BCD technology has excellent visibility as the display contrast increases in direct sunlight. Due 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 be used at night too 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 pixels though 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.
