Wave 2.9" E-Ink Flex Display for Pi

This is a flexible E-Ink display. Compared with normal e-Paper panels, this flexible panel allows bending without being damaged, and it's thinner and lighter.
Combined with the advantages like ultra low power consumption, wide viewing angle, clear display without electricity, it is an ideal choice for applications where curved surface display is required, such as industrial instruments, smart wearable-devices, and so on.
