Bi-stable LCD uses 99% less power than traditional LCDs

Lumex Inc. announces the global launch of its InfoVue Bi-Stable family of displays, a low-power LCD solution suited for a wide range of applications where display information is not changed more than a few times a day. For some applications, the Lumex InfoVue Bi-Stable LCD requires up to 99% less energy consumption than traditional LCD technologies.

A traditional LCD module requires 25 to 50 mW of constant power to display even a static, unchanging image. Lumex´s Bi-Stable LCDs can display the same information for more than a year after power has been turned off with just a one-time 2 to 5-second burst of 10 mW of power. The new technology enables users to more easily update vital display information while also generating cost and manpower savings.

Compatible with a variety of LCD configurations, the bi-stable 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 control, 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)


The InfoVue Bi-Stable LCD features an innovative cholesteric solution in place of the traditional twisted nematic liquid crystal solution. This feature allows the LCD to provide consistent performance with extremely low energy requirements. This provides significant cost savings for applications transitioning away from higher-energy consuming traditional LCDs.

Cost savings are also available for printed display applications transitioning to bi-stable LCD technology. The InfoVue Bi-Stable LCDs represent a low-energy alternative to the economic and environmental costs of repeatedly printing variable displays. Additionally, significant savings in time and cost are generated by the fact that displays can be centrally updated on a computer rather than manually updated throughout a venue.

InfoVue Bi-Stable LCD technology comes with complimentary integration support. Lumex technical design specialists can integrate the bi-stable technology with LEDs, light pipes, switches, connectors, and other key components to create solutions that maximize performance and efficiency in each individual application.

The RoHS-compliant LCDs are available in custom sizes to 9.5 in. Samples are available in a 2.8-in. size with 128 x 64 resolution. Displays are available in black-on-yellow or blue-on-white color formats.
