Nokia is working on a bendable display2
The information comes from a patent that Nokia has already registered and it reveals interesting details about displays that can change their physical form. Any device equipped with such a screen would probably have to feature interface that switches between modes depending on the current shape of its display, which is yet another challenge that software developers would need to address. The patent describes the integration of such displays into cell phones, but there are indications that the technology is applicable to a wide range of consumer devices like music players, notebooks etc.
We will certainly keeps tabs on any developments relating to devices equipped with bendable displays, although we don´t really think it´s quite likely that we see any in the next 2-3 years.
