Magnetic Adhesion for Display Panel Curved Surfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the manufacturing of display apparatuses, existing methods struggle to ensure precise and complete adhesion of panel members to cover members, especially on bent or curved surfaces, often resulting in inadequate bonding and the formation of air bubbles or foreign substances trapped between the components.
Innovation Solution
An apparatus and method utilizing a first mold with a magnetic guide and a shape-variable unit to control the adhesion process, where a magnetic force guides the panel member to contact the cover member sequentially from a flat portion to curved portions, ensuring precise and rapid adhesion while minimizing the occurrence of air bubbles and foreign substances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a panel member is adhered to a bent or curved cover member using conventional methods, then the adhesion process becomes complex and time-consuming, but the adhesion quality is insufficient with air bubbles and foreign substances trapped
Solution Approach 1:
The patent replaces conventional mechanical adhesion methods with a magnetic field-based system. A magnetic guide unit generates a magnetic field that acts on a magnetic substance embedded in the panel member, enabling precise control of the panel member's movement and adhesion to the cover member without complex mechanical mechanisms
Solution Approach 2:
The patent introduces a magnetic substance as an intermediary between the panel member and the magnetic guide unit. This magnetic substance mediates the interaction by being attracted to the magnetic guide unit, thereby controlling the panel member's position and movement during the adhesion process
2Reliability
If conventional adhesion methods are used on flat and curved surfaces, then the process time increases, but the adhesion is incomplete and unreliable
Solution Approach 1:
The patent applies different magnetic field intensities to different regions of the panel member through the magnetic guide unit. The magnetic field intensity is higher at curved portions and lower at flat portions, enabling tailored adhesion control for different surface geometries and ensuring complete, reliable adhesion across the entire panel member
Solution Approach 2:
The magnetic guide unit dynamically adjusts the magnetic field distribution during the adhesion process. By controlling the movement and positioning of the magnetic guide unit, the system adapts the magnetic field application to the specific geometry of the cover member, ensuring reliable adhesion on both flat and curved surfaces

AI summary
An apparatus for manufacturing a display apparatus includes: a first mold configured to accommodate a cover member thereon; a magnetic first guide in the first mold; a second mold arranged to face the first mold; and a magnetic shape-variable unit in the second mold. The shape-variable unit is configured to come into contact with and move a panel member toward the cover member, and a first portion of the panel member is configured to contact the cover member before a second portion of the panel member contacts the cover member due to a magnetic force between the shape-variable unit and the first guide.
