Display Panel Cushioning for Local Stress Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing image display apparatuses suffer from display unevenness due to local stress on the display panel, particularly when the lower end is caught by the panel holder or subjected to external forces, leading to deformation and stress that is not relieved unless the panel is disengaged, causing localized brightness issues and reduced display quality.
Innovation Solution
The image display apparatus incorporates cushioning members between the display panel and the holding member, with a higher pressing force applied to the lower side than the other sides, to reduce local stress and prevent display unevenness by suppressing movement and stress on the panel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the display panel is held by the panel holder at the lower end, then the display panel is supported and positioned, but the weight of the display panel and burrs cause the lower end to be caught on the panel holder, leading to deformation and stress
Solution Approach 1:
The holding structure is segmented into multiple pressing members distributed at different positions (upper end, lower end, left side, right side) rather than a single panel holder at the lower end. This distributes the supporting force and prevents localized catching and deformation.
Solution Approach 2:
Pressing members apply counteracting forces at multiple positions to balance the weight of the display panel. The pressing forces are specifically designed to counteract gravitational force and prevent the lower end from being caught, eliminating the harmful effect of weight-induced deformation.
2Adaptability or versatility
If the display panel is subjected to external force or vibration, then the display panel may move to an offset position, but the lower end gets caught on the panel holder and fails to return to the original position, causing deformation
Solution Approach 1:
The pressing members are designed with elastic bodies that can dynamically adjust to external forces and vibrations. The elastic bodies deform under external force and then restore the display panel to its original position, providing dynamic stability rather than rigid constraint.
Solution Approach 2:
Elastic bodies are placed between the pressing members and the display panel to provide beforehand cushioning. This cushioning allows the system to absorb external forces and vibrations without causing the display panel to get caught and deform, enabling recovery to the original position.
3Force
If static pressure or impact is applied directly in the display area, then the entire screen is locally stressed, but the stress is prevented from being relieved, causing display unevenness
Solution Approach 1:
The pressing force is segmented and applied at multiple discrete positions (upper end, lower end, left side, right side) rather than uniformly across the entire display area. This prevents concentrated stress in the display area while maintaining overall panel stability, allowing stress to be relieved without causing display unevenness.
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
This configuration effectively reduces local stress on the display panel, preventing display unevenness by ensuring the lower side is securely held, thus maintaining even brightness and improving display quality.
Implementation Method 1
cushioning members disposed between the display panel and the holding member such that a pressing force depending on an amount of deformation is applied to the display panel

AI summary
An image display apparatus including a display panel, a holding member holding four sides of the display panel, and cushioning members disposed between the display panel and the holding member such that a pressing force depending on an amount of deformation is applied to the display panel, wherein a pressing force acting on the display panel through the cushioning member for a lower side among the four sides of the display panel is higher than a pressing force acting on the display panel through the cushioning members for other sides of the display panel.
