In summary: Color e-ink displays are becoming more common in e-readers and tablets. While they may not be as vibrant as smartphone panels, their ability to show thousands of colors is a promising step for the technology. Zack Nelson from JerryRigEverything found that they also look fascinating under a microscope.
Nelson recently examined a Note Air 3 from Boox, which features E-Ink Kaleido 3 display technology also seen in Kobo’s Clara Colour and Libra Colour e-readers. Before conducting durability tests, he used a 230x digital video microscope from Dino-Lite to inspect the display.
The micro capsules appear different from traditional pixels under magnification, confirming it is an RGB display using red, green, and blue to create 4,000 colors. While this is fewer than modern displays, it is suitable for graphic novels or colored comics.
E-ink displays are highly energy efficient, but that’s a topic for another time.
There is also a resolution difference between color and black and white. The color display is limited to 1,240 x 930 (150 PPI) while black and white can reach 2,480 x 1,860 (300 PPI), which can be seen under magnification.
The tablet uses textured plastic instead of cover glass that scratches at level four on the Mohs Hardness Scale, with deeper grooves at level five. However, upon closer inspection, it is revealed that Boox has applied a plastic sheet over traditional cover glass. Removing the plastic provides a clearer view of the e-ink micro capsules.
