E Ink Spectra 6 technology

E Ink Spectra 6is a newly launched full color e-paper technology that brings fresh vitality to the e-paper industry with excellent color performance, high resolution and high contrast.
Adopts red, yellow, and blue as the primary colors, it offers more possibilities for e-paper color display, featuring high contrast and high saturation to make images clearer and colors brighter.

Spectra displays are made of millions of Microcups which suspend the four different colored particles in clear fluid.

By applying a negative charge the red particles rise to the top and become visible

A split charge raises blue particles to the top and become visible

More advanced performance

The resolution is up to 200ppi, features a wider range of operating temperature and faster screen refresh time. And it is more power-saving, aligning with ESG trends for energy efficiency and carbon reduction

Innovative microcup full color technology platform

Using blue charged particles to produce six primary colors, and employing dithering technology to create vivid and saturated full color images.

Advantages of EINK

E-paper display utilizes microcapsule electrophoretic technology for displaying, the principle is: charged particles suspended in clear fluid will move to sides of microcapsule when electric field is applied, making the microcapsule become visible by reflecting ambient light, just as traditional printed paper.
E-paper display will clearly display images/texts under lamplight or natural light, requires no backlight, and features nearly up to 180° viewing angle. It is usually used as e-reader due to its paper-like effect.

Standard Raspberry Pi 40PIN GPIO header

for connecting with controller boards like Raspberry Pi/Jetson Nano/RDK X3
