These are OLED and E Ink screens
As part of CES 2023, the Chinese manufacturer Lenovo showed a ThinkBook Plus Twist convertible laptop with two screens: OLED and E Ink. This may be important for those who are critical of laptop battery life.
Due to the form factor, the user can choose which screen he needs. OLED provides high brightness and full color mode, but E Ink dramatically reduces power consumption, while it is also color.
In technical terms, the OLED display provides a brightness of 400 cd / m 2 at a resolution of 2.8K and an image refresh rate of 60 Hz. It provides full coverage of the DCI-P3 color gamut. The screen itself is touch sensitive.
The 12-inch E Ink color touch display provides a frequency of only 12 Hz, which is not enough for games, but enough for text documents, web content and so on.
Inside, there is a 13th generation Intel Core processor, up to 16 GB of RAM and up to 1 TB of permanent memory, as well as a 56 Wh battery. It is claimed that when working only with the E Ink screen, this will last up to 21 hours. Also, the laptop is equipped with two Thunderbolt 4 (USB Type-C) ports and a 3.5 mm audio output.
The price starts at $1649, deliveries should begin in June 2023.
