![]() I have seen a few 10.3 with Kaleido Plus, and the colors looked really good at 117 PPI, which was increased beyond the standard 100 PPI, via software enhancements. At this time, all will have the same resolution.” This seems like a NO to me, so how will 150 PPI look on a 13.3? Will colors be bright and vibrant? We might have to wait for an official release to make the ultimate call. It has been optimized for 7.8, 10.3 and finally 13.3 Will the color resolution increase beyond 150 PPI on larger displays? E INK told me “Potentially yes – mainly as the TFT resolution will dictate the final resolution of the display. One of the big advancements in this new color e-paper is support for larger screens. An example of software being able to increase frames is with various speed modes, such as A2 or Onyx Boox X-Mode. It is achieved by an updated module hardware design with enhanced compatible waveforms, and customer’s software enhancements. The framerate will be 8-9 frames per second. When used with E Ink Kaleido Plus or E INK Kaleido 3, the color contrast ratio and color saturation increase by 40% and 15% respectively, providing an enhanced display for color ebook and digital textbooks.Į INK Kaleido 3 will be able to play videos, similar to other e-paper. This new technology dramatically increases performance of black and white displays by 30% and increases the contrast ratio, providing readers with clearer and more defined text. It will be the new standard going forward, and capacitive displays will be a thing of the past. E Ink’s new technology incorporates touch directly into the e-paper – making the display clearer for the end-user and the cost of materials lower for device manufacturers. E INK also disclosed to Good e-Reader that K3 is compatible with On-Cell Touch, which is only found on the Onyx Boox Nova 3 Color. It includes all of the benefits of 1200, except it reduces the latency in drawing with a stylus, so pen to screen is quicker. It is also compatible with Carta 1250, which is primarily designed for digital note taking devices. The main benefits is 30% performance increase, across the board. It is now compatible with E INK Carta 1200, which the latest generation Amazon Kindle Paperwhite and Paperwhite Signature edition employ. With the Advent of Kaleido 3, E INK put a priority on supporting their latest generation screens. Kaleido and Kaleido Plus were only compatible with E INK Carta HD display panels, this limited the number of digital note taking devices that employed the technology. ComfortGaze was not exclusively designed for Kaleido 3 in mind, instead it will be compatible with traditional e-readers and e-notes that use a black and white display panel. In the past, most front light designs did not address both of these color spectrums, and they were tuned specifically for the aesthetics of the light color to the viewer, rather than the eye health benefit. What is the deal with the new ComfortGaze technology? ComfortGaze was specifically designed to be within certain guidelines for BLR and BLTR. E INK is also using RBGW colors and not CMYK. The tradeoff is energy efficiency, and eye fatigue. LCDs using CFA do not have this issue given that they are emissive. Do colors look washed out as previous versions of Kaleido? E INK said K3 reduces the light scatter and loss of color. ![]() The company did further updates to the print pattern, in the past they used glass and they switched over to plastic. This was accomplished by putting the Color Filter Array closer to the ink layer. Kaleido 3 managed to increase the color accuracy to 150 PPI. ![]() The last few generations of color e-paper could only display 4,096 colors and 100 PPI. How does the innerworkings of this new color e-paper work? Additionally, the responsiveness of the ink means that Kaleido 3 can play animations and videos. BLR is the ratio of toxic blue to total blue light output, and BLTF is the ratio of brightness to hazardous blue. Kaleido 3 also uses E Ink ComfortGaze, a new front light technology that reduces the amount of blue light, with a reduced Blue Light Ratio (BLR) and Blue Light Toxicity Factor (BLTF) by up to 60% and 24% respectively. It offers richer colors, increasing its color saturation by 30% compared to the previous generation, E Ink Kaleido Plus, in addition to 16 levels of grayscale and 4,096 colors. The 3rd generation color e-paper, E Ink Kaleido 3 is now available for e-readers and digital note taking devices.
