Bendable Display Panel Hollow Region Circuit Stress Relief

The patent moves the peripheral circuits from the traditional planar non-display region into a three-dimensional configuration by bending the bendable region away from the light-exiting surface. The circuits are positioned in a spatial dimension outside the display plane, allowing the display region to extend to the edges of the screen while maintaining circuit functionality. This dimensional transition resolves the contradiction by eliminating the trade-off between having control circuits and achieving high screen-to-body ratio.

The patent introduces a hollow region as an intermediary stress-relief structure between the bending axis and the display region. This hollow region acts as a mediator that absorbs and distributes the stress generated during bending, preventing stress concentration that would otherwise lead to defects. The hollow region enables the bendable region to be bent away from the light-exiting surface while maintaining reliability by managing the mechanical stress.

The patent positions the peripheral circuits in a three-dimensional space outside the display plane by bending the bendable region. This spatial repositioning allows the circuits to be located in an accessible position for manufacturing and maintenance while not occupying the planar display area. The circuits remain accessible through the bent structure, resolving the contradiction between maximizing display area and maintaining circuit accessibility.
