Description

Mobile terminal

Technical Field

The application belongs to the technical field of electronics, and particularly relates to a mobile terminal.

Background

With the development of mobile terminal technologies such as smart phones, screens of mobile terminals are more and more designed, for example, a screen structure with a side screen formed by bending the edge of the screen backwards by a small arc (generally less than 90 degrees) is called a 3D curved screen. When the arc of the backward bending of the screen edge is larger than 90 degrees, that is, the arc of the bent portion of the screen side is larger than 90 degrees, the bent portion of the screen side looks like an "inverted" when viewed from the back, and is called an inverted screen. A middle frame is generally disposed in a mobile terminal to support a screen, so as to ensure the strength of the screen. In order to support the screen well, the shape of the middle frame is generally configured to match the shape of the screen. If the middle frame is matched with and supports the inverted screen, the side face, matched with the side screen of the inverted screen, of the corresponding middle frame is an arc-shaped face protruding outwards. And because the side screen bending of back-off screen is greater than 90 degrees, its side screen is incurved promptly, and this can lead to the back-off screen when the installation, the side of center can be scraped to the inner limit of its side screen, and leads to the back-off screen to be scraped badly.
