What is E Ink Carta Plus

E Ink Carta Plus is the latest generation of screens made by "electronic paper" technology. Compared to the previous models, this screen has a higher definition and contrast. Pixel density of the screen is 300 dpi that is a record for this type of E Ink screens and corresponds to the high-quality paper printing. Reading on such screens is as comfortable as on regular paper pages.

What is SNOW Field?

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+ technology enables one 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.

What is MOON Light+?

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 + 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.

Capacitive Multi-touch screen

E Ink Carta Plus display has a lighter base and higher contrast than other screens of this class. It allows one to read in bright sunlight and has a high rate of screen refresh. Absence of a shimmering light and the principle of image formation with E Ink method makes reading comfortable for eyes. Capacitive sensor, supporting a Multi-touch function, provides an easy control with fingers.

Additional screen protection

Protective glass from the famous Japanese manufacturer ASAHI is located atop the E Ink screen and protects it from scratches and other damage. This new glass allows to avoid additional frames, so the screen is flush with the body of the device. This makes the e-book more comfortable and it looks more modern. In addition a special coating reduces the glare of the screen.

After installing the firmware, you need to calibrate the battery. Before calibrating, you must reset the device to factory settings (Settings> Right arrow (top right of the screen)> Reset to factory settings). During the reset process, uncheck the "Clear internal memory" box, otherwise all files will be deleted. The procedure consists of four stages:
- Write down the books that you will read soon.
- Charge the book to the maximum without removing it from the charge until the orange LED turns off.
- After that, disconnect from charging and use the device in normal mode until the battery is completely discharged (the cable icon appears with a request to charge), regardless of the rate of battery discharge. In the process of discharging, the reader cannot be connected to a computer or charger. Also, before the process is complete, you cannot do a factory reset.
- Then recharge the book with continuous charge up to 100 percent.
