E-ink (electronic ink) displays come in several types, each optimized for different applications. Here’s a breakdown of the main types of e-ink displays:
Description: The most common and widely used type. Shows text and simple graphics in black and white.
Applications: E-readers like Amazon Kindle, basic electronic shelf labels (ESL), industrial devices.
Advantages: Low power, high readability in sunlight, cost-effective.
Limitations: No color, limited refresh rate.
Description: Similar to monochrome but supports multiple levels of gray (4–16 shades).
Applications: E-readers that want to display images with shading, medical/industrial displays.
Advantages: Better visual depth than pure black & white.
Limitations: Still no full color, slow refresh.
First-generation color e-ink, supports thousands of colors.
Rarely used now due to lower saturation and contrast.
E Ink Kaleido (Kaleido, Kaleido Plus, Kaleido 3)

In summary:
Monochrome / Grayscale → Text-focused (e-readers, labels).
Color (Kaleido / Gallery / Triton) → Color e-readers, signage.
Carta / Mobius → High-res or flexible e-readers.
Spectra → Retail labels (3-color).
Prism / JustWrite → Design and handwriting applications.
