Lifetime and Environmental Stability
The lifetime of the display is directly correlated with the number of switching cycles that are performed. One switching cycle is counted when the display is switched from OFF -> ON -> OFF. The degradation of the display is caused when a voltage is applied to turn the display off (from colored to bright state). Close to no degradation is caused if the display is constantly on (colored) or when it is constantly off (bright state). With accurate driving, the lifetime will exceed 100 000 switching cycles.
The temperature range is from -20 to +80 degrees Celsius.
The displays are not sensitive to UV.
The display operates in conditions where the relative humidity (RH) is in the range of 5-95%.
General Technology Questions
No. The rdot display and E Ink display are fundamentally different technologies. They both share the same principle of being reflective display technologies, meaning that they reflect ambient light and that no backlight is needed. E Ink is an electrophoretic technology. The Rdot Display is utilizing organic electrochromic materials.
