Notched Retaining Wall for Flexible LCD Uniformity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The closed retaining wall structure in flexible liquid crystal display panels affects the uniformity of alignment solution and liquid crystal dispersion during the celling process, leading to display quality issues and the generation of dead pixels.
Innovation Solution
Incorporating notches in the retaining wall structure around sub-pixel regions on the flexible liquid crystal display panel allows for the circulation and self-adjustment of liquid crystals when the panel is bent, ensuring uniform diffusion and alignment of liquid crystals, thereby improving display quality and reducing dead pixels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a closed retaining wall structure is used to define sub-pixel regions, then the structural integrity and boundary definition are improved, but the uniformity of alignment liquid and liquid crystal diffusion deteriorates
Solution Approach 1:
The retaining wall is segmented by introducing notches that divide the closed structure into sections, allowing alignment liquid and liquid crystal to diffuse uniformly across sub-pixel regions while maintaining overall structural integrity
Solution Approach 2:
The retaining wall has different properties in different locations: solid walls provide structural integrity and boundary definition, while notched regions provide diffusion pathways for uniform liquid crystal distribution, achieving local optimization of both functions
2Shape
If a closed retaining wall structure is used, then the boundary definition of sub-pixel regions is improved, but the circulation and self-adjustment of liquid crystals during bending deteriorates
Solution Approach 1:
The retaining wall structure is made dynamic by adding notches that allow liquid crystals to move and circulate when the display panel is bent, enabling self-adjustment and adaptation to mechanical deformation while maintaining clear boundary definition
3Manufacturing precision
If notches are added to the retaining wall, then the uniformity of liquid crystal distribution is improved, but the structural integrity may deteriorate
Solution Approach 1:
Notches are strategically positioned at specific locations within the retaining wall where they provide necessary diffusion pathways without compromising the overall structural integrity, achieving local optimization of liquid crystal distribution while maintaining global structural strength
