Bi-stable Cholesteric technology is truly unique in that it doesn’t require any power to drive the display. Power is only necessary when the image is refreshed; image would be retained after power off. No Polarizer or backlight is needed without any viewing angle penalties, resulting in a thinner and lighter display. This makes it perfect for applications such as signage, price labels, e-books and USB memory sticks where updating is less frequent.

Key features:

  • High resolution (VGA, SVGA, XVGA or even higher)
  • Extreme wide viewing angles (nearly 180°)
  • Wide operating temperature range
  • Exceptional sunlight readability
  • Various colour combinations
  • Zero power consumption



For advice regarding a suitable display for your application, please contact us, we will be more than happy to assist.

*All Varitronix displays offer a range of backlight colour and temperature range options.
