What E Ink Kaleido 3 is...

E Ink Kaleido 3 screens display 4096 colors color mode and 16 shades of gray in black and white mode. Optimization of the screen structure allowed to increase the intensity of colors by 30% compared to the previous generation. The E Ink Kaleido 3 uses E Ink Print Color ePaper technology, in which the color filter array (CFA) complements the basis of the E Ink Carta 1200, allowing you to output full-color images.

What SNOW Field (Regal) is...

SNOW Field (Regal) is an operating mode of the screen, allowing you to reduce the number of artifacts on the screen during partial refresh. If this function is on, full refresh of the screen is not needed.

Dual touch control

Tab Ultra С has two touch layers. Above the surface of the screen there is a capacitive layer supporting multi-touch, thanks to which you can turn book pages and zoom documents with intuitive finger pinches. In addition, there is a Wacom touch layer under the E Ink panel, so you can make notes and sketches using a special stylus coming with the device. The stylus recognizes 4096 degrees of pressure and allows you to draw with amazing accuracy.

Screen frontlit system

Screen frontlit system

MOON Light 2 technology allows you to use the device in the dark or in poor lighting conditions, without any harm to your sight. When using this function, a soft glow of the screen is being created which is optimal for reading in dark rooms. This front light system has a color temperature adjustment, and thanks to the use of Flicker-Free technology, shimmering of the screen is completely absent.

What MOON Light 2 is...

The latest researches have shown that blue light prevents the production of melatonin (daily rhythms regulator), which is necessary for a person to sleep. Therefore, after reading on a glowing screen of an ordinary tablet or smartphone, it is often difficult to fall asleep. MOON Light 2 allows you to adjust the brightness of cold and warm LED lights independently, choosing at will white light for reading during the daytime, and more yellow for reading before sleeping.

Flicker-Free

The Flicker-Free technology completely eliminates shimmering of the LEDs used in this screen frontlit system. This is due to the use of a DC power supply. The Flicker-Free technology significantly reduces discomfort for sight and eye fatigue and decreases the chances of headache, caused by long use of the E Reader.

The built-in camera with a 16MP matrix and special software with OCR technology allow you to scan documents, recognize text information and save it to a file in internal memory.

Additional screen protection

Protective ONYX Glass is located on the E Ink screen and protects it from scratches and other damage. The new glass made it possible to abandon additional screen borders, so the screen is flush with the body of the device. This makes working with this E Reader more comfortable and its appearance is more modern. In addition, a special coating reduces the likelihood of glare on the screen.

What ONYX Glass is...

ONYX Glass is a fundamentally new generation of protective glasses from ONYX. Aluminosilicate glass has increased transparency and ensures the absence of distortion of the original image. The glass is applied on top of the front light layer without an air gap during the manufacturing the display module. Instead of applying a matte layer, which can reduce contrast, 5% etching is used. It provides improved glare protection and does not hamper light passing.
