What E Ink Carta is...

E Ink Carta is the newest development of E Ink Company. This is a display made on the "electronic paper" technology. Reading on such a screen is as comfortable as on ordinary paper. Compared to previous generations of ePaper, this screen has a lighter base and higher contrast.

What the SNOW Field is...

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

Screen frontlight

The MOON Light 2 technology allows you to use the device in the dark or under poor lighting conditions. When this function is in use, soft luminescence of the screen comfortable for reading in dark rooms is being generated. It also has a color temperature control and, thanks to the use of Flicker-Free technology, the front-light system is perfectly smooth.

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. The Flicker-Free technology completely eliminates shimmering of the LEDs used in this screen front light 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.
