Electronic equipment with a curved screen, such as a mobile phone, generally adds a function bar on the curved edge of the curved screen, such as quickly calling out important contacts and common applications, so that the set important contacts or common applications can be called out at any interface and the edge of a sliding screen. However, in the using process of the curved screen, because no corresponding mistaken touch prevention device is arranged, when a user operates/holds the mobile phone with one hand, the problem of misoperation often occurs because the root of the thumb is in contact with the edge of the curved screen, and the interface of the mobile phone is switched to the desktop of the quick contact person.

In order to solve the above problem, as shown in fig. 1 and 2, an electronic device according to an embodiment of the present application includes: curved screen 18, frame 1 and electro-deformable member 5.
