Display Technologies

In the transmissive mode, the display is illuminated from the rear side to make the segment visible. This technology is used for indoor applications, with low ambient brightness.

In the transflective mode, a partially transmissive reflector foil is placed behind the LCD. The reflector reflects the bright ambient light or the direct sunlight, and the back light can at the same time go through the reflector foil. This kind of technology is used basically for outdoor applications.

The bi-stable cholesteric display technology (ChLCD) requires no energy for displaying information. Power is only required during update times. ChLCDs are reflective display systems, the segments become visible by reflection of the incident ambient light. Informations are readable under all light conditions and a backlight is not needed.

Geameleon® are colored, high-resolution, large-area displays based on the bi-stable ChLCD technology. This display technology is optimized for indoor and outdoor applications.

With TFT flat screens, informations can be colored displayed. The high resolution matrix display systems are used for indoor or outdoor applications with no direct sunlight.
