BOOX ePaper with Kaleido 3: The Duet of Efficiency and Color

3 mins read

The colors of the illustrations look serene and dreamy on paper, leading us into a realm of fantasy. Such experience can hardly be replicated on LED screens. However, thanks to the advances in ePaper technology, it's now possible for us to relive such wistful reverie in a digital way. And what makes it happen is Kaleido 3.

What is Kaleido 3?

Kaleido 3 is E Ink's latest generation of print color display technology for ePaper products. Compared with conventional black-and-white E INK displays, Kaleido uses an RGB Color Filter Array (CFA) to present colors on the screen. With a color filter on top, red, green, and blue can be mixed or with black and white to create a total of 4,096 colors.

Kaleido 3's Edges Over the Last Generation

E INK has produced three generations of Kaleido modules: Kaleido, Kaleido Plus, and Kaleido 3. As the latest generation, Kaleido 3 fares better in color display quality, eye-health protection, and response time.


1. Enhanced Color Saturation and Resolution

The color saturation of Kaleido 3 was improved by 30% compared to the previous generation. Moreover, Kaleido 3 raised the color display resolution from 100 PPI to 150 PPI. As a result, images are like faded watercolors being retouched, popping, and captivating eyes.


2. Gentle Front Light to Protect Eyes

Along with Kaleido 3 is a new front light technology, ComfortGaze. The light is shed evenly onto the screen and then perceived by human eyes just like the ambient light. More importantly, ComfortGaze reduces the Blue Light Ratio (BLR) and Blue Light Toxicity Factor (BLTF) by up to 60% and 24% respectively.

3. Quicker Response Brought by Better Compatibility

Kaleido 3 is compatible with Carta 1200 and Carta 1250 which can bring overall upgrades in response, creating a smoother experience in handwriting and animation playing. Furthermore, the display is polished up with a higher contrast ratio. The enhancement derived from Kaleido 3 is holistic. That is why BOOX was quick to embrace it once it hit the market.
