Solution Overview

Problem

Flexible display panels face structural instability and risk of signal line breakage under external forces due to the deformation of flexible cover plates, which compromises their mechanical performance and stability.

Innovation Solution

Incorporating a via that passes through the bending component in a direction substantially perpendicular to the display surface, accommodating a support structure that connects with the flexible cover plate, thereby providing structural support and preventing signal line breakage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of moving object

If the flexible cover plate is deformed to achieve narrow bezel design, then the screen ratio is increased, but the signal lines are prone to breakage under external forces

Engineering Contradiction:

Improvescreen ratioVSAvoidsignal line integrity

Core Design Contradiction:

Area of moving objectVSReliability

Solution Approach 1:

A support structure is pre-installed within the via of the bending component to provide protective support to the signal lines before external forces are applied. This cushioning effect prevents the signal lines from breaking during subsequent deformation or bending operations, resolving the contradiction between achieving narrow bezel design and maintaining signal line integrity.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

Solution Approach 2:

The support structure acts as an intermediary element between the flexible cover plate and the signal lines. It mediates the mechanical stress by providing a rigid support within the via, preventing direct transmission of external forces to the signal lines while allowing the flexible cover plate to deform for narrow bezel design.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If the bending component is made flexible to enable foldability, then the adaptability is improved, but the structural stability deteriorates

Engineering Contradiction:

ImprovefoldabilityVSAvoidstructural stability

Core Design Contradiction:

Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The support structure is locally positioned within the via of the bending component, providing rigid support only at the critical location where signal lines pass through. This localized reinforcement maintains structural stability at the via region while preserving the overall flexibility and foldability of the bending component, resolving the contradiction between adaptability and structural stability.

Inventive Principle:

Principle #3Local quality
