Outdoor Digital Signs - Using E Ink

Using E Ink's epaper display technology these outdoor displays are visible in direct sunlight and ultra-low-power. In addition if there is no power the image will remain on the display.

E Ink Technology

E Ink Technology

E Ink's e-paper technology uses normal printing pigments in a liquid that can be moved from the front to the back of microcapsules making up the display as illustrated below.

The reason E Ink's displays are so low power is twofold:

● They hold their image without power, referred to as bistable, so once the image is written to the display it remains there until an updated image is written. Added to this is is possible to just update the part of the image that needs changing rather than the whole image. Other display technologies such as LCD and LED typically have the image updated 60 times a second.

● They are reflective so like normal paper they rely on ambient light, this is one of the reasons they are so effective as sunlight readable displays. Other display technologies are emissive, ie light shines from them. LCD typically has an LED backlight and LED, which is often referred to as direct view LED, is in effect a lamp. OLED is like LED, the pixels themselves emit light.

Applications

Applications

The benefit of being low power and sunlight readable makes E Ink displays uniquely suitable for outdoor displays, expecially where there is no power source as they can be powered by solar.

These sign type applications can make use of the widely avaialble live data feeds that are then formatted for the display as well as user created text based messaging using templates or free form graphics. Volanti provides demonstration applications together with source code.

Suitable For Solar Power

Suitable For Solar Power

E Ink displays are ultra-low power so well suited for solar power installations, this frees them from the constraints of being located near sources of mains power. A typical installation with solar would also include a battery.
