Nokia has filed a patent application entitled "Autostereoscopic rendering and display apparatus", in which it is a 3D-technology, and do not require special glasses. The patent has a sketch and description of Nokia 3D Communicator. This unit is made in the clamshell form factor and is equipped with two displays: the top with the support of three-dimensional images and the lower, touch, where are the controls.

Design complements several frontal cameras. They are designed to monitor the eye movements of users to the best way to create a clear three-dimensional image just from the standpoint of the user. In this case, he did not need glasses and when changing the angle of the picture will remain clear. The development also provides for the following point: 3D objects from the upper display will cast a shadow on the bottom screen. The solution is really unusual, and the Finnish company remains only to realize it.
