OLED Panel Fastening Using Embedded Bottom Cover Magnets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing OLED devices face challenges in combining and separating the OLED panel and bottom cover due to strong adhesive forces, leading to potential damage and misalignment issues, which affect productivity and ease of manufacturing.
Innovation Solution
Incorporating magnets into the bottom cover to securely fasten the OLED panel, allowing for easy assembly and disassembly, and preventing misalignment by using magnetic forces instead of double-sided tape.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If double-sided tape is used to combine OLED panel and bottom cover, then strong adhesive force is achieved, but difficulty in separation and potential damage occur
Solution Approach 1:
The combining mechanism is segmented into multiple independent magnets distributed across the bottom cover, allowing localized control and easy separation by removing individual magnets rather than dealing with a monolithic adhesive bond
Solution Approach 2:
The mechanical adhesive bonding system (double-sided tape) is replaced with a magnetic field-based combining system, enabling non-contact attachment that can be easily controlled and separated through simple removal of magnets
2Strength
If double-sided tape is used to combine OLED panel and bottom cover, then strong adhesive force is achieved, but productivity deteriorates
Solution Approach 1:
Magnets are pre-installed in the bottom cover before OLED panel assembly, eliminating the need for time-consuming adhesive application and curing processes during manufacturing, thereby improving productivity
Solution Approach 2:
The time-consuming adhesive bonding process is replaced with rapid magnetic attachment, allowing for faster assembly and disassembly operations that significantly improve manufacturing productivity
3Strength
If double-sided tape is used to combine OLED panel and bottom cover, then strong adhesive force is achieved, but misalignment occurs in curved type OLED device
Solution Approach 1:
Multiple magnets are distributed at specific positions across the bottom cover, providing independent alignment control points that maintain precise positioning even in curved OLED devices where uniform adhesive force causes misalignment
Solution Approach 2:
The uniform adhesive bonding mechanism is replaced with distributed magnetic fields that provide controllable, position-dependent attraction forces, enabling precise alignment while accommodating curved geometries
4Ease of operation
If magnets are used to fasten display panel to bottom cover, then easy assembly and disassembly is achieved, but device complexity increases
Solution Approach 1:
The magnets are extracted as separate, removable components from the bottom cover structure, allowing for easy assembly and disassembly operations while keeping the overall device structure relatively simple and modular

AI summary
An organic light emitting display device is disclosed which includes a magnet inserted into a bottom cover. The magnet is used to combine an organic light emitting display panel with a support means which is used to support the organic light emitting display panel and includes an upper cover, the bottom cover and a side cover. A sealing member included in the organic light emitting display panel is fastened to the bottom cover by a magnetic force of the magnet. As such, it is easy to separate the organic light emitting display panel and the support means from each other when a fault is generated in any component. In accordance therewith, the manufacturing process can be simplified and the faulty component can be easily replaced with a normal component. As a result, the manufacturing costs of the organic light emitting display device can be reduced.
