Note:

Refresh time: The refresh time is the experimental results, the actual refresh time will have errors, and the actual effect shall prevail. There will be a flickering effect during the global refresh process, this is a normal phenomenon.Power consumption: The power consumption data is the experimental results. The actual power consumption will have a certain error due to the existence of the driver board and the actual use situation. The actual effect shall prevail.

Working Principle

This product is an E-paper device adopting the image display technology of Microencapsulated Electrophoretic Display. The basic principle is that charged nanoparticles suspended in a liquid migrate under the action of an electric field. The E-paper screen display patterns by reflecting the ambient light, so it has no background light requirement. Under ambient light, the E-paper screen still has high visibility with a wide viewing angle of 180 degrees. It is the ideal choice for E-reading.

Provide online user manual, please check the manual carefully before using. With development resources and manual(driver board schematic, examples for Raspberry Pi/Arduino/STM32).
Doesn’t support partial refresh. No backlight, keeps displaying last content for a long time even when power down.
Low power, wide viewing angle, paper-like effect without electricity. Ideal for price tags, shelf labels, industrial instruments…
Ultra low power consumption, basically power is only required for refreshing.
Red/Yellow/Black/White display color. Outline dimension (raw panel): 45.5mm x 36.4mm x 0.91mm.
