The third generation Fujitsu Quaderno will have an E INK Carta 1250 display panel. This is the same one that they employed on the second generation model that came out in 2021. Basically, you get all of the advantages of Carta 1200, found on many of the most popular e-readers in the world, such as the Kindle Paperwhite and Kobo Sage, however with 1250 you get improved pen latency, so it is more responsive with freehand drawing, editing PDF files or taking notes.
The A4 features a 13.3 inch screen with a resolution 2560×1920 with 240 PPI, this is a huge visual upgrade from the second generation model which had a resolution of 1650 by 2200 with 227 PPI. One of the big selling points is this is the first large screen display to use Kaleido 3. This new e-paper has support for 4096 different colors and there is a wider color gamut and 30% better saturation. However, there is a drawback with this new screen, the color PPI is only 80. This is attributed to the fundamental way that Kaleido 3 handles PPI differently. It takes the overall black and white PPI and cuts it by 1/3 and this is what the color PPI will be. There is no front-lit display on this model, however it is using a WACOM layer and will come with a new stylus. You will also be able to bring in your own stylus.
The production model had Android and full APK support, but it remains unknown if Fujitsu will support apps or not.
