Electrophoretic Display (ED)

CFAP128296B0-0290 is a 2.90" graphic e-paper display, red + 3-level grayscale ‒ front view with power off, FPC unfolded.Electrophoresis is defined1 as The migration of electrically charged molecules through a fluid or gel under the influence of an electric field.”

electro2– Latinized form of Greek elektro- refers to an electrical charge
-phoresis3 – From Greek phorēsīs being carried, from pherein to bear

An Electrophoretic Display (or ED for short) is also known as ePaper.

The electrically charged molecules are black or red ink particles that move — and become visible to the viewer — when an electric field (voltage) is applied. When all of the black and red modules are moved away, the display appears white.

ED modules are typically thin, very low power, and sunlight-readable. Once an image is displayed, they require no power to operate until the display needs to update or change.

Get Started with e-Paper Displays

Crystalfontz carries several e-paper modules. For a quick introduction to this type of display, check out this blog post.

For a fast start, use our sample code to display your images. Our clean, open-source demonstration code runs directly on a low-cost Seeeduino v4.2 (3.3v Arduino clone).

For assistance in determining what module is the best one for your application, please contact our knowledgeable and friendly support staff by email, phone, or chat. We are here to answer any questions that you may have about e-paper modules or any of the LCD, TFT, and OLED modules we carry.
