Abstract: Example mobile terminals are disclosed. One example terminal includes a rotating member, a flexible screen, a bending support part, and a temperature equalization plate. The flexible screen includes two unfolded regions and a bent region that is disposed opposite to the rotating member. The bending support part is located between the flexible screen and the rotating member. The temperature equalization plate is configured to balance temperatures in the two unfolded regions and includes two temperature equalization parts opposite to the two unfolded regions in a one-to-one correspondence and a flexible connection part that connects the two temperature equalization parts. The flexible connection part is located on a side of the bending support part and away from the flexible screen.

Abstract: This application provides a foldable screen device. The foldable screen device in this application includes two frames that are jointly articulated with a rotating shaft assembly. The two frames may rotate around rotating shafts of the rotating shaft assembly to be closed or opened. The rotating shaft assembly includes a connection structure and hinges. The connection structure has a channel that passes through two opposite sides of the rotating shaft assembly, and an electrical connection line of the foldable screen device penetrates into the channel. Two ends of the electrical connection line are respectively connected to the two frames, and the hinges and the channel are located at different positions of the rotating shaft assembly in an axial direction. In this way, bending deformation generated by the electrical connection line when the foldable screen device is folded is relatively small, and connection reliability is high.
