Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display panels with outer bending designs suffer from poor impact resistance at the bent portion due to the supporting steel plate, leading to increased risk of display failure upon impact.
Innovation Solution
A display panel design featuring a support member with a first support portion and a second support portion, where the second support portion is in a bent state and has a lower stress buffering capacity than the first, utilizing materials like stainless steel and foam to enhance impact resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a supporting steel plate is provided on the back of the display panel to meet bending performance requirements, then the bending performance is improved, but the impact resistance deteriorates
Solution Approach 1:
The support member is divided into multiple support portions (first support portion, second support portion, third support portion) with different stress buffering capacities. Each portion is positioned at different locations on the back of the display panel to provide differentiated support: the first support portion provides strong support for structural stability, the second support portion provides moderate support for bending performance, and the third support portion provides weak support to allow impact absorption, thereby resolving the contradiction between bending performance and impact resistance.
Solution Approach 2:
Different regions of the support member are assigned different material properties and stress buffering capacities. The first support portion uses material with high stress buffering capacity for strong support, the second support portion uses material with moderate stress buffering capacity for bending support, and the third support portion uses material with low stress buffering capacity for impact absorption. This local differentiation allows each region to perform its specific function optimally.
2Volume of moving object
If the display screen is positioned at the outermost bottom of the display device to achieve outer bending design, then the device size is reduced, but the impact resistance deteriorates
Solution Approach 1:
The third support portion is specifically designed with low stress buffering capacity and positioned at the outermost bottom where the display screen is located. This creates a predetermined cushioning zone that can absorb impact energy before it reaches the display screen, providing beforehand protection against impact while maintaining the compact outer bending design.
Solution Approach 2:
The support member acts as an intermediary structure between the display screen and the device frame. The third support portion serves as a mediator that allows controlled deformation and impact absorption, protecting the display screen from direct impact forces while enabling the outer bending design that reduces device size.
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 design improves impact resistance at the bent portion by distributing and absorbing impact forces, reducing the risk of display failure and maintaining structural integrity under stress.
Implementation Method 1
a stress buffering capacity of the first support portion is less than a stress buffering capacity of the second support portion
Implementation Method 2
a material of the second support portion includes foam

AI summary
The present disclosure discloses a display panel and a display device. The display panel includes a first support portion which supports a side of a first flexible display portion, and a second support portion in a bent state which supports a side of a second bending portion, wherein a stress buffering capacity of the first support portion is less than a stress buffering capacity of the second support portion, so as to improve impact resistance of the second bending portion through the second support portion, and reduce a risk of failure of the display panel due to impact on the second bending portion.
