Guoyue Color K3 - Kaleido 3 e-note

Here is a new e-note in town. The Guoyue K3 Color comes with a 10.3-inch E Ink Kaleido 3 display. The display specs should be familiar by now, including support for 4096 colours and 300 PPI resolution in Black and White mode, which drops down to 150 PPI for coloured display. The company said the colour saturation is enhanced by 30 percent. At the same time, a microcrystalline etching panel is used to simulate 256 levels of grayscale, which the company said helps eliminate ghosting significantly.

Another highlight of the new Guoyue K3 Color e-note is its adoption of the XRapid fast refresh algorithm that results in a refresh rate of 12 frames per second. Then there also is ComfortGaze front light technology onboard, allowing for adjustable brightness and colour temperature. All of this reduces blue light reflection by 60 percent, while damage caused by blue light exposure is decreased by 24 percent.

Further, the Guoyue K3 Color has its reading engine, xReader. It supports five pen types, 16 handwriting colours, five levels of width adjustment, and four sharing or export options. Then there are more than 100 note templates available too. Making up the core of the e-note is an octa-core 2.3 GHz chipset that works in tandem with 4GB of RAM and 64GB of storage, the latter being further expandable to up to 1TB. There are also four integrated microphones as well as dual speakers.

Connectivity options with the Guoyue K3 Color include Bluetooth 5.0 and Wi-Fi (2.4G + 5G), while a USB Type-C port is also onboard for charging and data transfer. The e-note also comes with a fingerprint scanner embedded within the Power button. Running the entire show is Android 11. The bundled pen supports 4096 levels of pressure sensitivity.
