E Ink’s digital paper, often called ePaper, has found a home in e-readers, displays, and even covering cars. Balancing the need for high-quality displays and power requirements has always been a challenge. It started as a grayscale display, but color ePaper displays have been available for a while.
The latest generation, E Ink’s Kaleido 3, takes the quality to a new level. It can deliver 16 levels of grayscale and 4,096 colors. This new display increases color saturation by 30% compared to the earlier Kaleido Plus. It can display animations and videos.
The Kaleido 3 employs a color filter array (CFA) that’s used in conjunction with E Ink’s Carta black-and-white ink film. The display also uses the company’s ComfortGaze, a front-light technology designed by E Ink's Front Light Team. The technology reduces the amount of blue light reflected off the surface of the display and lowers the blue light ratio (BLR) by 60% and blue light toxicity factor (BLTF) by 24%. This provides more comfortable viewing for users.
The E Ink Kaleido 3 module is available in 7.8-, 10.3-, and 13.3-in. versions. It targets eBooks as well as other display applications.
