In the mobile terminal of the prior art, since the edge of the cover is designed with a 2.5D curved surface, the distance from the camera located at the gap of the display screen to the edge of the cover is the distance from the camera to the 2.5D curved surface plus the 2.5D curved surface. If the width is too large, the distance from the camera to the edge of the mobile terminal is too large, so that the screen ratio of the mobile terminal is not high. In the mobile terminal 10 of the present application, since the first surface 310 has a light incident area extending to the side peripheral surface 330 , the light incident area is set on the first transition surface 341 and the second transition surface 342 (the first transition surface 341 and the second transition surface 342 ) The second transition surface 342 may be a 2.5D arc surface) so that the camera 400 can be partially or completely disposed in the light incident area, and the camera 400 is closer to the edge of the cover 300 , that is, the edge of the mobile terminal 10 (the camera 400 to the cover The distance from the edge of 300 can reduce the width of the 2.5D arc surface), thereby increasing the screen ratio of the mobile terminal 10 and enhancing the user experience.
