Display mechanism and vehicle

The display mechanism comprises a display screen assembly, a supporting assembly and a base assembly, the supporting assembly comprises a first supporting device and a second supporting device, and the first supporting device and the second supporting device are respectively connected with the display screen assembly. The first supporting device and the second device are movably connected into the first sliding groove and the second sliding groove in a matched mode so as to drive the display screen assembly to deform in a concave-convex mode, rolling friction exists between the first supporting device and the first sliding groove, and rolling friction exists between the second device and the second sliding groove. Therefore, the first supporting device and the second supporting device can drive the display screen assembly to generate concave-convex deformation, different arc radians of the display screen assembly are achieved, and a foundation is laid for efficient utilization of the display mechanism in different scenes. The first supporting device and the first sliding groove are in rolling friction, the second supporting device and the second sliding groove are in rolling friction, deformation resistance of the display screen assembly can be reduced, and deformation of the display screen assembly is smoother.
