Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional liquid crystal display apparatuses experience deformation and pooling effects when pressed, especially in touch control displays, leading to reduced display quality due to liquid crystal molecule dissipation and alignment changes.
Innovation Solution
Incorporating a display apparatus with a first and second substantially transparent magnetic layer on opposite sides of a display substrate, both having the same magnetic polarity to generate a repulsive force, reducing deformation and pooling effects by preventing liquid crystal molecule dissipation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a touch panel is added to enable touch control functionality, then user interaction capability is improved, but deformation and pooling effects occur when pressed, leading to reduced display quality
Solution Approach 1:
The patent introduces a magnetic layer with opposite magnetic polarity between the touch panel and display substrate to generate a repulsive force that counteracts the pressing force applied during touch operations. This repulsive magnetic force acts as a counterweight to the mechanical pressure, preventing deformation of the display substrate and eliminating pooling effects while maintaining touch control functionality.
Solution Approach 2:
The patent changes the magnetic polarity parameter of the magnetic layer to create a repulsive force field. By setting the magnetic polarity of the magnetic layer in the touch panel opposite to that of the magnetic layer on the display substrate, the system generates a repulsive magnetic force that dynamically counteracts external pressing forces, thereby maintaining display quality during touch interactions.
2Length of moving object
If the display substrate is made thinner to reduce overall device thickness, then device compactness is improved, but the substrate becomes more susceptible to deformation under pressure
Solution Approach 1:
The patent replaces the mechanical support structure with a magnetic field-based support system. Instead of relying solely on the mechanical strength of a thicker substrate, the invention uses a magnetic layer with opposite polarity to generate a repulsive magnetic force that compensates for the reduced mechanical strength of thinner substrates, thereby preventing deformation while maintaining device compactness.
Solution Approach 2:
The magnetic layer acts as a virtual counterweight that provides upward support force to counteract the downward pressing force on the thin display substrate. This magnetic counterweight effect allows the substrate to remain thin while maintaining sufficient resistance to deformation through the repulsive magnetic force.

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 repulsive force between the magnetic layers significantly reduces deformation in the display substrate, thereby minimizing pooling effects and maintaining display quality even under pressure, including from touch panel interactions.
