OLED Display Connecting Member With Magnetic Bodies
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing OLED displays face challenges in reliably supplying power due to the potential for film cracking when bent and damage during compression processes, which can lead to panel damage and unreliable connections.
Innovation Solution
The OLED display employs a connecting member with magnetic bodies and elastic pin-type terminals, eliminating the need for a power supply film and avoiding compressive processes, ensuring stable power supply through conductive layers and pads with varying thicknesses to maintain connection reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a film for power supply is compressed and bonded to the power supply pad, then power can be supplied to the OLED, but the film may crack when bent and cause panel damage
Solution Approach 1:
The patent extracts and removes the power supply film from the system, replacing it with direct bonding between the sealing member (which has integrated conductive layers) and the FPC. This eliminates the film that was causing cracking issues while maintaining the power supply function through the sealing member's conductive layers.
2Reliability
If compression process is used to bond the film for power supply, then electrical connection is established, but panel damage may occur during compression
Solution Approach 1:
The patent removes the compression bonding process by integrating the conductive layers directly into the sealing member, which is then bonded to the FPC without requiring separate film compression steps. This eliminates the harmful compression effects on the panel while achieving reliable electrical connection.
3Reliability
If a power supply film is used to connect power supply pad, then power can be supplied, but the connection may be unreliable due to film cracking
Solution Approach 1:
The patent merges the conductive layers with the sealing member structure, creating an integrated component where the sealing member contains first and second conductive layers that directly provide power supply connections. This eliminates the separate power supply film and its associated integrity issues.

Function Achieved in This Case
This solution allows for reliable power supply to OLED displays without the risk of film cracking or panel damage, facilitating assembly and detachment while maintaining connection stability and preventing deformation of terminal portions.
Implementation Method 1
Each of the first and second connecting members may include a case body; pin-type first and second terminal portions respectively coupled to opposite side portions of the case body, each terminal portion having an elastic force substantially perpendicular to a lower surface of the case body; and magnetic bodies inserted into the case body disposed in areas corresponding to the first and second pads.

AI summary
An organic light-emitting diode (OLED) display is disclosed. In one aspect, the OLED display includes a substrate, an organic light-emitting portion, a sealing member, and first and second connecting members. The organic light-emitting portion includes a first electrode positioned on the substrate, an organic light-emitting layer formed on the first electrode, and a second electrode formed on the organic light-emitting layer. The sealing member includes a first conductive layer positioned on the organic light-emitting portion and electrically connected to the second electrode, a second conductive layer electrically connected to the first electrode, and an insulating layer interposed between the first and second conductive layers. The first connecting member is connected to the first conductive layer to supply a first power source, and the second connecting member is connected to the second conductive layer to supply a second power source.
