Double-Layer Support Member for Flexible OLED Panels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing support members for flexible OLED display panels fail to effectively match the shape of the panels, leading to reduced product yield and success rate in development, as they do not adequately decompose resilient forces and prevent delamination.
Innovation Solution
A double-layer support member comprising a flexible first support plate with deformable regions and a rigid second support plate, where the first support plate is bonded to the second through an adhesive layer, allowing the first deformable region to match the bending region of the display panel and decompose overall deformation stress, preventing delamination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a single rigid support plate is used to strengthen the display panel, then the support strength is improved, but the ability to match the bending shape of the flexible panel deteriorates
Solution Approach 1:
The support plate is segmented into a first support plate with deformable region and a second support plate with rigid region, allowing different parts to serve different functions - the first plate matches the bending shape while the second plate provides structural support
Solution Approach 2:
Different regions of the support structure are given different mechanical properties - the first support plate has flexible local quality to match the bending shape, while the second support plate has rigid local quality to provide strength
2Adaptability or versatility
If a single flexible support plate is used to match the bending shape, then the shape adaptability is improved, but the support strength deteriorates
Solution Approach 1:
The support structure is divided into two functional segments: a flexible first support plate for shape matching and a rigid second support plate for strength, combining both requirements in one system
Solution Approach 2:
The support structure uses a composite configuration of flexible and rigid materials/structures, where the first support plate (flexible) and second support plate (rigid) work together to provide both shape adaptability and structural strength
3Strength
If the support plate is made thicker to increase rigidity, then the support strength is improved, but the flexibility to match bending regions deteriorates
Solution Approach 1:
The support structure is segmented into thickness zones - the first support plate has smaller thickness for flexibility while the second support plate has greater thickness for rigidity, allowing both properties to coexist
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The double-layer support member enhances structural stability and product yield by reducing resilient forces and preventing delamination between the support member and the display panel, ensuring improved support and shape matching for flexible OLED display panels.
Implementation Method 1
a first adhesive layer, arranged on a side of the first support plate; and a second support plate, bonded to the side of the first support plate through the first adhesive layer
Implementation Method 2
the first support plate includes a first deformable region defined with a plurality of openings; the first deformable region of the first support plate is fitted with the bending region of the display panel

AI summary
A support member, a display module and a display device are provided. The support member is configured for supporting a display panel and includes: a first support plate, being a flexible plate, the first support plate includes a first deformable region defined with a plurality of openings; a first adhesive layer, arranged on a side of the first support plate; and a second support plate, bonded to the side of the first support plate through the first adhesive layer, where a rigidity of the second support plate is greater than a rigidity of the first support plate, and the second support plate includes a second deformable region fitted and fixed with the first deformable region and corresponds to the bending region of the display panel.
