3.0 Segmented Display Options and the Electronics Ecosystem

E Ink offers two types of Segmented displays: Segmented Display Cells (SDCs), and

Segmented Display Modules (SDMs).

SDCs are independent display cells that do not include any embedded electronics; they can be

driven at either 5V or 15V. Typically, SDCs are used in simpler designs with lower segment

counts and fewer pin outs. Designs that have adequate space and less restrictive PCB

integration needs are ideal for SDC applications.

SDMs include an integrated E Ink display driver for a complete display solution, typically for

designs that have demanding integration requirements. SDMs simplify the integration effort by

reducing the number of pin outs required between the MCU and display. As a result, less space

is needed for connection to the PCB.

3.1 5V Segmented Display Cell (SDC)

E Ink Segmented Display Cells (SDCs) can be driven as low as 5V, depending upon the nature

of the application. At 5V, contrast/reflectance will be 60-80% of the performance at 15V, and

will refresh at 720 milliseconds.
