EPD Product Selection – The Best E-ink Displays for Industry & IoT

The different types of E ink material film (FPL)

E ink film type	Temperature range	Colors	Operating temperature	Storage temperature	Remark
Aurora	Zero above	black, white (BW)	0°C to +50°C	-20°C to +60°C	Standard monochrome display for most indoor operating conditions. Support fast updates.
Aurora -25	Freezer	black, white (BW)	-25°C to +30°C	-25°C to +60°C	Suitable for freezing operating conditions.
Wide Temperature	Wide	black, white (BW)	-15°C to +60°C (Fast Update: 0°C to +50°C)	-25°C to +70°C	New generation of our unique monochrome display and support fast updates. (-20°C is workable)
Spectra Red	Zero above	black, white, red (BWR)	0°C to +40°C	-25°C to +60°C	3-colors pigments inside. Taking longer time to complete a refresh.
Spectra 4	Zero above	black, white, red, yellow (BWRY)	0°C to +40°C	-25°C to +60°C	New generation of color display upgraded by BWR to provide additional yellow.

Note that EPDs are suitable for refresh cycles (global update, full-screen update) from tens of seconds to minutes.
Fast update rate (partial update – few hundred milliseconds) is feasible, but please share your requirements with us for further support.
EPDs are more suitable for applications where a static image is maintained without electricity and doesn’t need to be refreshed frequently.

Determine whether the operating temperature or color is the primary requirement for your product or use case.
If having red or yellow as one of the EPD colors is essential, please note that Spectra EPDs cannot be operated at sub-zero temperatures and do not support Fast/Partial refresh.
If your product needs to operate below 0°C, wide-temperature EPD (black and white) will be the only suitable model. Selecting Freezer if your case needs temperature down to -25°C.
We recommend selecting Wide Temperature if a three- or four-colors display is not essential, which also features lower power consumption, ghosting resistant and fast screen refresh.
