Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Liquid crystal display panels face issues with light leakage and display quality due to displacement of structural layers under external forces, which affects contrast and viewing angle, particularly in large-size panels.
Innovation Solution
A display panel design featuring magnetic subunits with opposite magnetic polarities on two substrates, which attract each other, ensuring stability and preventing displacement under external forces, with the magnetic subunits being part of a black matrix or spacer layers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional structural layers are used in liquid crystal display panels, then the panel can be manufactured with standard materials and processes, but the structural layers displace under external forces causing light leakage and reduced display quality
Solution Approach 1:
The patent replaces conventional mechanical bonding methods with magnetic attraction to hold structural layers in place. Magnetic particles are embedded in the black matrix and spacer layers, creating magnetic fields that attract opposing layers together, preventing displacement under external forces and eliminating light leakage without requiring additional mechanical fastening structures.
Solution Approach 2:
The patent introduces magnetic properties as a new parameter to the structural layers. By embedding magnetic particles and creating magnetic fields within the black matrix and spacer layers, the system gains the ability to resist external forces through magnetic attraction, fundamentally changing how structural stability is achieved from purely mechanical to magnetomechanical coupling.
2Reliability
If magnetic particles are embedded in structural layers to prevent displacement, then structural stability is improved, but the manufacturing process becomes more complex
Solution Approach 1:
The patent merges the magnetic stabilization function with the existing black matrix and spacer layer structures. The magnetic particles are embedded directly into these layers during standard manufacturing processes, combining structural support and magnetic attraction functions into single integrated layers rather than adding separate magnetic components or assembly steps.
Solution Approach 2:
The black matrix and spacer layers serve multiple functions simultaneously: they provide structural support, define display regions, and now also provide magnetic attraction through embedded particles. This multi-functionality eliminates the need for additional dedicated magnetic components, reducing overall device complexity despite the enhanced stabilization capability.
3Object-affected harmful factors
If magnetic particles are used to maintain structural position, then light leakage is prevented, but the display panel becomes sensitive to magnetic fields
Solution Approach 1:
The magnetic particles are localized specifically within the black matrix and spacer layers at positions where they provide maximum structural stabilization. The magnetic fields are confined to these specific regions rather than being distributed throughout the entire display panel, allowing light leakage prevention where needed while minimizing overall magnetic field sensitivity in the display area.
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 magnetic attraction maintains structural stability, preventing light leakage and enhancing display quality by ensuring uniform thickness and position of the black matrix, even under external forces, thereby improving the overall performance of the display panel.
