Flexible Display Reinforced Insulating Layer Bending Resistance

The inorganic insulating layer is divided into multiple regions: a first insulating region and a second insulating region with different material compositions or structures. This segmentation allows each region to have optimized properties - the first region provides insulation while the second region enhances bending resistance, resolving the contradiction between insulation performance and bending resistance

The patent uses composite material structures where the insulating layer combines different inorganic materials or integrates with organic flexible layers. This composite approach maintains the insulation functionality while introducing materials with better flexibility and bending resistance, preventing cracking during repeated bending

Different regions of the insulating layer are designed with different qualities - the first insulating region maintains full insulation coverage while the second insulating region has modified properties to enhance flexibility. This local differentiation ensures insulation functionality is preserved where needed while bending resistance is improved in other areas

The patent introduces a vertical dimension to the insulating layer structure by creating multi-layer configurations or varying thickness across different regions. This dimensional change allows the insulating function to be maintained through sufficient insulation depth in critical areas while reducing horizontal coverage in areas requiring flexibility, thus resolving the contradiction between insulation functionality and bending resistance
