Abstract: A display panel is disclosed in the present application. A display portion is bent about at least a first direction to define a first arc shape, and the first arc shape has a first radius of curvature. A driving chip is bonded to a pad portion. A support pad is provided between the display portion and the pad portion, and is provided corresponding to at least the driving chip. The support pad includes a first surface toward the display portion and a second surface toward the pad portion, the first surface is in contact with the first arc shape, and the second surface is a flat surface.

Abstract: A zero-stiffness impact isolation device includes a shell, a half-hourglass-shaped boss, a sliding block, a spring, a motion guide assembly, and an inner core. Where the motion guide assembly includes a linear bearing fixed to the shell and the inner core and a corresponding sliding rod, and is divided into a transverse guide assembly and a longitudinal guide assembly. The spring is sleeved outside the sliding rod of the transverse motion guide assembly, and two ends of the spring are in contact with the sliding block and the inner core, respectively. When the device suffers from external impact load, the inner core and the separated object carry out a reciprocating motion, the sliding block is extruded by the half-hourglass-shaped boss to move side to side with respect to the inner core, and the spring provides elastic force to the sliding block in the process.
