Grooved Support Members for Two-Sided OELD Panels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Two-sided emission Organic Electroluminescent Display (OELD) devices require a support structure that does not interfere with the light emission path, as light is emitted from the emission layer towards both the substrate and encapsulation substrate, necessitating a support system that exposes portions of the top and bottom surfaces of the panel while securely holding the panel without obstructing the light path.
Innovation Solution
A support system comprising a first support member with a groove for one side of the panel and a pair of second support members with grooves for the opposite sides, allowing the panel to be securely positioned and exposing portions of the top and bottom surfaces, which can be made from thin metallic plates and may be separate or combined as a unitary body, ensuring the light emission path is not obstructed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a support member is used to hold the flat display panel, then the panel is securely supported, but the support member may obstruct the light emission path from the two-sided emission OELD panel
Solution Approach 1:
The support member is divided into multiple segments: a first support member with a first groove for supporting one side of the panel, and a pair of second support members with second grooves for supporting the opposite sides. This segmentation allows the panel to be held securely at multiple points while maintaining exposure of the top and bottom surfaces for light emission.
Solution Approach 2:
The support members are designed with grooves that provide localized support only at the edges of the panel, while the central display areas remain completely exposed. This local quality approach ensures that support function is concentrated where structurally necessary, while light emission paths remain unobstructed in the display regions.
2Reliability
If the support members cover the entire panel for secure holding, then the panel is well-supported, but portions of the top and bottom surfaces corresponding to the display element cannot be exposed
Solution Approach 1:
The support structure uses multiple discrete support members positioned at specific locations rather than a continuous covering, allowing selective exposure of the display surfaces while maintaining support at critical points.
Solution Approach 2:
The support members provide localized support at the panel edges while leaving the central display areas completely exposed, optimizing both support stability and light emission surface area.
3Device complexity
If a single unitary support structure is used, then the structure is simple, but it may not provide adequate support for all four sides of the panel
Solution Approach 1:
The support system uses a first support member for one side and a pair of second support members for the opposite sides, providing distributed support across multiple edges while maintaining structural simplicity through modular design.
Solution Approach 2:
The support members are designed to be versatile, with grooves that can accommodate the panel thickness and provide support for different panel configurations, making the modular support system adaptable to various display panel sizes and types.

AI summary
An apparatus for supporting a two-sided emission Organic Electroluminescent Display (OELD) panel having a display element includes: a first support member having a first groove and supporting one side of four sides of the flat display panel; and a pair of second support members each having a second groove and supporting opposite sides excluding the one side of the four sides of the flat display panel. A side opposite to the one side of the four sides of the flat display panel is exposed, and the flat display panel is arranged in the first groove of the first support member and the second grooves of the pair of second support members and is supported by the first support member and the pair of second support members.
