Magnetic Layer Substrate Stabilization for Display Panel Ripple Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display panels experience relative displacement between substrates under pressure, leading to ripples and light leakage due to the flow of liquid crystals and misalignment of the black matrix layer, which degrades display quality.
Innovation Solution
Incorporating a first and second magnetic layer with opposite polarities on the substrates to form an attractive magnetic field force, preventing relative displacement and maintaining the position of the black matrix layer, thereby reducing ripples and light leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional display panels are used, then the structure is simple, but relative displacement occurs between substrates under pressure causing ripples and light leakage
Solution Approach 1:
The patent replaces mechanical bonding structures with a magnetic field-based holding mechanism. Magnetic layers with opposite polarities are deposited on the substrates to generate attractive magnetic forces that prevent relative displacement under pressure, eliminating the need for complex mechanical bonding structures while improving display quality by preventing ripples and light leakage
Solution Approach 2:
The patent changes the physical state and properties of the substrates by introducing magnetic layers with specific polarities. This parameter change enables the substrates to interact through magnetic fields, transforming the holding mechanism from mechanical to magnetic, thereby preventing relative displacement without adding mechanical complexity
2Stability of the object's composition
If magnetic layers with opposite polarities are added, then relative displacement is prevented, but the structure becomes more complex
Solution Approach 1:
The patent replaces mechanical bonding structures with a magnetic field-based holding mechanism. Magnetic layers with opposite polarities are deposited on the substrates to generate attractive magnetic forces that prevent relative displacement under pressure, eliminating the need for complex mechanical bonding structures while improving display quality by preventing ripples and light leakage
Solution Approach 2:
The patent uses composite material structures by combining magnetic layers with the substrate materials. The magnetic layers are deposited on the substrates to create a composite structure that provides both the original substrate functionality and the magnetic holding capability, achieving stable substrate position without excessive structural complexity

AI summary
The general inventive concepts relate to display technology, and provides a display panel, a display device, and a method for fabricating a display panel. It reduces ripples in the display panel and light leakage around the pixel region from occurring when the display panel is subject to a pressure. The display panel comprises a first and second substrate which are arranged oppositely. The first substrate comprises a black matrix layer and a first magnetic layer. The second substrate comprises a second magnetic layer which corresponds to the first magnetic layer in position. The first and second magnetic layers form an attractive magnetic field force between the first and second substrates.
