E Ink Aurora™
E Ink Aurora™ was developed to address retailers' needs to integrate digital signage into cold temperature display cases, such as refrigerators or freezers. With operating temperature ranges of -15 to 10 degrees C and 0 to 50 degrees C, Aurora offers the same benefits as E Ink's other display platforms - paper-like readability with a wide viewing angle. In addition, displays using Aurora are low power, running off of 2 small cell batteries, with a life-time of 5 years.
