Segmented E-ink Display -- FAQ
Q: What is the difference between an epaper matrix display and an epaper segmented display?
A: The underlying ePaper technology is very similar but is tuned to the needs of the different applications of a matrix display versus a segmented display.
Matrix displays are intended for applications requiring the display of many different forms of text and images. These displays comprise of a large array of pixels. These individual pixels are controlled by a TFT array similar to what you will have a typical computer monitor or TV screen.
Segmented displays are intended for applications where the display requirements can be met using predefined segments that can be turned on or off. This is similar to what one would see in a typical calculator with a numeric or alphanumeric display.
