Organic Light Emitting Display Reinforcing Lattice Impact Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Organic light emitting displays face challenges in withstanding external impacts, leading to potential deformation and breakage due to the lack of adequate reinforcement between the display panel and the bezel.
Innovation Solution
A reinforcing lattice is interposed between the display panel and the bezel, comprising a meshed structure of horizontal and vertical ribs, preventing direct contact between the substrates and enhancing the durability of the display panel by distributing external forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple frame structure is used to accommodate the display panel, then the device complexity is reduced, but the strength and impact resistance of the display panel deteriorates
Solution Approach 1:
The frame is constructed as a composite structure combining a base frame and a reinforcing lattice made of different materials (metal and/or polymer). This composite design provides both structural simplicity and enhanced strength, resolving the contradiction between low complexity and high impact resistance.
Solution Approach 2:
The frame is segmented into two functional components: a base frame for accommodation and a separate reinforcing lattice for strength enhancement. This segmentation allows each component to be optimized independently while working together to provide both simplicity and strength.
2Device complexity
If direct contact between the display panel and base plate is allowed, then the device complexity is reduced, but the reliability under impact deteriorates
Solution Approach 1:
A reinforcing lattice is introduced as an intermediary element between the display panel and the base plate. This lattice acts as a mediator that distributes impact forces, preventing direct concentration of stress on the display panel while maintaining structural integrity.
Solution Approach 2:
The reinforcing lattice is pre-installed between the display panel and base plate to provide beforehand cushioning against potential impacts. This preventive structure absorbs and distributes impact energy before it can reach the display panel, enhancing reliability.
3Strength
If a reinforcing lattice is added between the display panel and bezel, then the strength and impact resistance are improved, but the device complexity increases
Solution Approach 1:
The reinforcing lattice is constructed from composite materials (metal and/or polymer) that provide high strength-to-weight ratios and ease of fabrication. This allows the lattice structure to enhance strength without proportionally increasing overall device complexity.
Solution Approach 2:
The frame system is segmented into modular components (base frame, reinforcing lattice, side walls) that can be manufactured separately and assembled. This segmentation simplifies the manufacturing process and reduces assembly complexity while providing enhanced strength through the lattice structure.
