Buffer Part for Impact-Resistant Display Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display devices, particularly OLED devices, are vulnerable to external impacts that can damage the sealing substrate and member, allowing moisture and oxygen to infiltrate and degrade the organic emission layer.
Innovation Solution
Incorporating a buffer part adjacent to the corner regions of the sealing part, which is designed to absorb and dissipate external impact, thereby protecting the sealing substrate and preventing moisture and oxygen infiltration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a sealing substrate and sealing member are used to seal the organic emission layer, then the display panel is protected from moisture and oxygen infiltration, but the sealing structure becomes vulnerable to external impact damage
Solution Approach 1:
A buffer part is positioned at the corner region of the sealing structure before external impact occurs. This buffer part absorbs and dissipates impact energy when external forces are applied, preventing the sealing substrate and sealing member from direct impact damage. The buffer part acts as a sacrificial element that protects the critical sealing components, thereby maintaining sealing integrity while improving impact resistance.
2Weight of stationary object
If the sealing substrate and sealing member are made thinner to reduce device weight, then the display device becomes lighter, but the sealing structure becomes more vulnerable to external impact
Solution Approach 1:
The sealing structure is divided into multiple functional components: the sealing substrate, the sealing member, and the newly added buffer part. Each component has a specific function - the sealing substrate and member provide the sealing barrier, while the buffer part provides impact protection. This segmentation allows the sealing components to remain thin for weight reduction while the buffer part handles impact resistance.
Solution Approach 2:
The buffer part serves as an intermediary element between the external environment and the sealing structure. It absorbs impact energy before it reaches the sealing substrate and sealing member, allowing the sealing components to be made thinner without compromising durability. The buffer part mediates the interaction between external impacts and the delicate sealing system.
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 buffer part effectively absorbs external impact, preventing damage to the sealing member and maintaining the integrity of the display panel by reducing the transfer of force to the sealing part, thus protecting the organic emission layer from degradation.
Implementation Method 1
The buffer part is proximate to a corner region of the sealing part to at least partially surround the corner region of the sealing part, the buffer part extending from the substrate to the sealing substrate... The buffer part effectively absorbs external impact
