Unlike traditional LCDs, InfoVue Bi-Stable LCDs do not require polarizers. The elimination of the polarizer offers an increase in light reflection for the displays, with less power consumption. The increased percentage of light reflection is also responsible for the increased contrast between pixels in the ON and OFF states—about 25:1 from directly in front of the display. A traditional LCD module requires 25 to 50mW of constant power to display even a static, unchanging image. InfoVue Bi-Stable LCDs can display information over a year after the power has been turned off with just a one-time 2-5 second burst of 10mW of power.
