Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display panels face challenges in maintaining stability and noise shielding, especially when bent, due to the lack of effective shielding mechanisms and structural flexibility, which can lead to functional layer breakdown and display disturbances.
Innovation Solution
A functional panel design incorporating a third region with a functional layer, a bonding layer, and a conductive film, where the conductive film is positioned between the functional layer and the bonding layer, forming a capacitor to shield noise and maintain stability during bending, with optional features like a base for external force protection and alternate bending directions to prevent breakdown.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the functional panel is designed to be bent for flexibility, then adaptability is improved, but the functional layer may break down and noise shielding deteriorates
Solution Approach 1:
The panel is divided into three distinct regions: a first region with the functional layer, a second region without the functional layer, and a third region that can be bent. This segmentation allows the bendable third region to accommodate flexibility requirements while the first region maintains functional integrity, resolving the contradiction between bending adaptability and functional layer stability.
Solution Approach 2:
Different regions of the panel are assigned different properties: the third region is designed with bendable characteristics while the first region maintains structural integrity for noise shielding. This local differentiation allows the panel to be bent in specific areas without compromising the overall stability and noise shielding performance of the functional regions.
2Object-affected harmful factors
If the conductive film is positioned closer to the functional layer for better noise shielding, then noise shielding is improved, but stress on the conductive film increases during bending
Solution Approach 1:
The panel structure segments the conductive film placement: in the first region, the conductive film is positioned between the functional layer and bonding layer for optimal noise shielding, while the third region is designed to be bent without the functional layer. This segmentation allows the conductive film to be close to the functional layer where needed for noise shielding while avoiding high-stress bending zones.
3Device complexity
If a single-layer structure is used for simplicity, then device complexity is reduced, but noise shielding and stability deteriorate
Solution Approach 1:
The panel employs a segmented three-region structure where each region serves a specific function. The first region contains the functional layer with conductive films for noise shielding, the second region provides structural support, and the third region enables bending. This segmentation achieves effective noise shielding and stability without requiring complex additional components.
Solution Approach 2:
The bonding layer serves multiple functions: it bonds the functional layer to the support structure, provides mechanical support, and contributes to noise shielding when the conductive film is positioned between the functional layer and bonding layer. This multi-functionality reduces the need for separate components, maintaining structural simplicity while achieving effective noise shielding.

Function Achieved in This Case
The solution provides a stable and noise-shielded functional panel that remains reliable and convenient, even when bent, by reducing stress on the conductive films and preventing functional layer breakdown, thus enhancing the panel's operational stability and display quality.
Implementation Method 1
A capacitor is formed between the first conductive film and the second conductive film. Thus, with the use of the first conductive film, the circuit can be shielded from a noise.
