Hollowed-Out Support Base Plate for Flexible Display Bending
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional flexible display panels have unsatisfactory bending performance due to the rigidity of their support base plates, which can lead to warping or breaking under bending stress, hindering the improvement of overall display panel performance.
Innovation Solution
A support base plate with a two-layer structure in the bending area, featuring a hollowed-out design with varying density and shape, such as a mesh or grid pattern, to reduce bending resistance and enhance flexibility, while maintaining structural support through an adhesive layer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the support base plate is made thicker and more rigid to provide structural support, then the structural strength is improved, but the bending performance deteriorates causing warping or breaking under bending stress
Solution Approach 1:
The support base plate employs different structural characteristics in different regions: the bending area uses a hollowed-out structure with lower density to enhance flexibility, while the non-bending area maintains solid construction for structural support. This local differentiation resolves the contradiction by providing flexibility where needed and strength where required.
Solution Approach 2:
The support base plate is divided into distinct functional regions: a bending area with hollowed-out structures and a non-bending area with solid support. This segmentation allows each region to be optimized for its specific function, enabling the plate to bend easily in the bending area while maintaining strength in the non-bending area.
2Reliability
If the support base plate is made thinner to improve bending performance, then the bending flexibility is improved, but the structural support capability deteriorates
Solution Approach 1:
The support base plate employs different structural characteristics in different regions: the bending area uses a hollowed-out structure with lower density to enhance flexibility, while the non-bending area maintains solid construction for structural support. This local differentiation resolves the contradiction by providing flexibility where needed and strength where required.
Solution Approach 2:
The support base plate combines different structural configurations (hollowed-out and solid) within a single component, creating a composite structure that exhibits both flexibility and strength. The hollowed-out structure in the bending area provides flexibility while the solid non-bending area provides structural support capability.

AI summary
A support base plate and a display panel are provided. In embodiments of this application, a support base plate in a bent area is correspondingly disposed as a structure having at least two layers. In the two-layer structure, at least one layer is a hollowed-out structure, and another layer is a support structure. When a flexible display panel is bent or folded, the support base plate provided in the embodiments of this application not only can support the panel, but also can effectively improve the bending performance of the panel, thereby improving the comprehensive performance of the flexible panel.
