The very thin and lightweight Yoga Book C930 features, aside from a UHD 10.8" display, a dynamic e-ink panel that can be converted, if required, into a keyboard, a notepad or an e-reader. For data input, a Bluetooth pen with 4,096 pressure stages is available and can be used to write on both displays. These displays are connected via a high-grade watchband hinge that allows the main screen to be completely folded back. In this way, the convertible laptop can be operated in the different modes.
