Flexible Display Module with Colloid Support for Narrow Bezel Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge is to enhance the structural stability of display modules with thin and narrow bezel designs while maintaining strength, as blindly reducing the thickness of support structures can lead to poor stability due to decreased strength.
Innovation Solution
A display module design featuring a flexible display panel with a bearing assembly and colloids in the bending space, where the colloids are connected to the back plates and buffer layers, providing support and ensuring strength even with reduced bending radius, and including a protective adhesive layer for enhanced stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the thickness of the support structure is reduced to achieve narrow bezel design, then the bezel width is reduced, but the structural stability and strength of the display module deteriorate
Solution Approach 1:
The patent changes the material parameters by introducing a colloid with specific viscosity characteristics (20,000-60,000 Cp) that provides structural support without requiring thick rigid support structures. This allows the binding area to be bent onto a thinner support structure while maintaining structural stability through the colloid's unique rheological properties.
Solution Approach 2:
The patent creates a composite structure combining the display panel, bearing assembly, and colloid material. The colloid forms a unified structure with the bearing assembly and display panel, creating a composite system that provides both flexibility for narrow bezel design and structural strength through the combined properties of all components.

If the thickness of the support structure is reduced to achieve narrow bezel design, then the bezel width is reduced, but the reliability of the display module deteriorates
Solution Approach 1:
The patent applies beforehand cushioning by pre-positioning the colloid in the bending space before the display panel is bent. The colloid's viscous properties allow it to cushion and absorb stresses during the bending process, preventing cracks and maintaining reliability. The colloid is disposed in advance in the bending space to provide protective cushioning when the panel is bent.
Solution Approach 2:
The patent changes the physical state parameters of the support structure by using a colloid that transitions from a viscous state during bending to a solidified state after bending. This parameter change allows the material to provide flexibility during manufacturing and structural stability during use, ensuring reliability after the bending process.
