Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional alignment methods capturing intersection points of boundaries are used, then the alignment process is simple, but alignment precision deteriorates due to the curved plane structure of three-dimensional foldable screens
Solution Approach 1:
An alignment mark structure is introduced as an intermediary element between the flexible display panel support and the display panel. This alignment mark structure includes a first alignment mark on the support body and a second alignment mark on the display panel, serving as a mediator to achieve precise alignment despite the curved surface geometry. The alignment marks provide a reference system that bridges the complexity of the curved surface with the need for precise positioning.
Solution Approach 2:
The alignment mark structure is pre-configured on both the flexible display panel support and the display panel before the actual assembly process. By establishing the alignment marks in advance during manufacturing, the complex alignment task is simplified during assembly, as the marks provide pre-established reference points that guide the positioning process.
2Ease of operation
If alignment marks are positioned in display areas, then alignment is facilitated, but display effect deteriorates due to visual interference
Solution Approach 1:
The alignment mark structure is specifically positioned in the non-display area of the flexible display panel, creating a local distinction between the display area (which maintains visual quality) and the non-display area (which contains the alignment marks). This local placement strategy allows the alignment marks to serve their function without interfering with the display effect, as they are confined to a region that does not affect the visual output.
3Adaptability or versatility
If the support body is made with curved plane structure for three-dimensional foldable screens, then the display functionality is improved, but alignment and attachment precision deteriorates
Solution Approach 1:
The support body is segmented into distinct functional regions: a plane region that provides a flat surface for precise alignment and attachment of the display panel, and curved regions that enable the three-dimensional foldable screen functionality. This segmentation allows different parts of the support body to serve different purposes - the plane region ensures manufacturing precision while the curved regions provide adaptability for foldable displays.
Solution Approach 2:
The alignment mark structure acts as an intermediary that connects the curved plane structure of the support body with the flat display panel. By providing reference marks that span across the transition from curved to plane regions, the alignment marks enable precise positioning despite the geometric complexity introduced by the curved surfaces.
