Bi-Stable LCD tech uses 99% less power than traditional twisted nematic LCDs

Lumex has announced the global launch of their InfoVue Bi-Stable LCD displays for applications where display information is not changed more than a few times a day. Lumex says for some applications its InfoVue Bi-Stable LCD requires up to 99% less energy consumption compared to traditional LCD technologies. The low power consumption is due to the use of innovative cholesteric solution in place of the traditional twisted nematic liquid crystal solution.

A traditional LCD module requires 25-50mW of constant power to display even a static, unchanging image. Lumex´s Bi-Stable LCDs can display the same information for over a year after power has been turned off with just a one time 2-5second burst of 10mW of power, says Lumex. Bistable technology can replace standard LCD technology or printed displays where information changes with less frequency than is the case for traditional LCD applications. Bi-Stable LCD applications include:
Retail Outlets (price and sale-announcement displays on shelves and throughout the store);
Industrial Controls (thermostat-related, automation controls and drive control applications);
Security (climate, alarm and access control displays on indoor security system panels);
Hospitality (displays in common areas as well as in rooms)

“InfoVue Bi-Stable LCDs provide significant cost savings and performance benefits to a number of niche display applications that have traditionally been addressed with print displays,” explained Brian Coates, Technical Sales Manager at Lumex. “For example, not only can a retail outlet save on printing supplies and manpower by no longer having to manually print and post pricing information throughout the store, they can also more easily provide additional variable information such as ´For Today Only´ or ´´Newly Reduced Price´ on their displays.”

The RoHs compliant InfoVue Bi-Stable LCDs are available in custom sizes ranging from ¼ inch to 9½ inches. Samples are available in a 2.8 inch size with 128x64 resolution. The displays are available in black-on-yellow or blue-on-white color formats.

Price: The 2.8 inch size is approx. US$10 to US$13 per unit
