Existing display devices face reliability issues during the manufacturing process due to potential damage from heat or pressure applied during the connection of driving circuits to the display panel, which can affect the integrity and performance of the components.
Innovation Solution
Incorporating a partition member with low thermal conductivity, such as a polymer material, between the main circuit part and the driving circuit part, and using heat or light reactive adhesion members to attach these components to the display panel, thereby preventing heat transfer and ensuring stable installation of the driving circuit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If heat or pressure is applied to connect the driving circuit to the display panel, then the driving circuit can be securely mounted, but other components may be damaged due to heat transfer
Solution Approach 1:
A partition member is introduced as an intermediary component between the main circuit part and the driving circuit part. This partition member blocks heat transfer from the main circuit part to the driving circuit part during the bonding process, thereby protecting the driving circuit part from heat damage while allowing secure mounting of the driving circuit to the display panel
Solution Approach 2:
The space between the main circuit part and the driving circuit part is segmented by the partition member, creating distinct thermal zones. This segmentation prevents heat generated during bonding of one component from affecting other components, allowing independent thermal management of different circuit parts
2Area of stationary object
If the driving circuit part is placed close to the display area, then the device size is reduced, but heat from the main circuit part can damage the driving circuit part
Solution Approach 1:
The partition member serves as a thermal barrier that enables close placement of the driving circuit part to the display area while preventing heat damage from the main circuit part. This allows compact device design without sacrificing component protection
