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
