Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a flexible display device is manufactured using a flexible process, then the display device can have various shapes and increased design flexibility, but mass production efficiency and manufacturing precision deteriorate
Solution Approach 1:
The display device is divided into separate components: a flexible display unit and a rigid cover window. The flexible display unit can be pre-manufactured and tested independently, then integrated with the cover window in a controlled assembly process. This segmentation enables standardized mass production of the flexible unit while maintaining design flexibility through various configurations.
Solution Approach 2:
An adhesive layer is introduced as an intermediary between the flexible display unit and the cover window. This adhesive layer enables reliable bonding while allowing the flexible unit to maintain its curved shape. The adhesive intermediary facilitates precise alignment and secure attachment during assembly, improving manufacturing precision.
2Shape
If a curved shape is implemented in the display device, then design flexibility and aesthetic appeal improve, but manufacturing precision and reliability deteriorate
Solution Approach 1:
The cover window is designed with a curved surface that matches the curvature of the flexible display unit. This pre-formed curved geometry guides the lamination process, ensuring precise alignment and consistent bonding across the curved surface. The curved design is maintained throughout manufacturing, eliminating deformation.
Solution Approach 2:
The cover window is pre-formed with its final curved shape and surface geometry before the lamination process. This preliminary formation ensures that when the flexible display unit is laminated onto the cover window, the curvature is already established, simplifying the lamination process and improving precision.
3Loss of substance
If the panel member size is reduced to match the curved surface area, then material utilization improves, but alignment precision and assembly difficulty worsen
Solution Approach 1:
The adhesive layer is designed to extend across the entire curved surface of the cover window, creating a uniform bonding area. This equipotential approach ensures consistent adhesive distribution and bonding strength across the curved surface, simplifying alignment and assembly while maximizing material utilization.

AI summary
A display device includes a cover window including a curved portion, and a panel member laminated on the cover window. A method of manufacturing a display device includes mounting a cover window including a curved portion on a first jig including a curved portion, mounting a panel member on a second jig that conforms to a surface of the first jig, and laminating the cover window to the panel member by moving a first one of the first jig or the second jig to a first other one of the first jig or the second jig. An apparatus for manufacturing a display device includes a first jig including a mount surface that is partially curved to conform to a surface of a cover window, a second jig including a surface conforming to the mount surface and configured to contact a panel member, and a driving unit.
