Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If separate production processes are used for different display device sizes, then manufacturing precision can be maintained for each size, but productivity decreases due to multiple dedicated production lines
Solution Approach 1:
The display device is divided into separate functional modules: active panels and driving panels. These modules can be manufactured independently using standardized processes, then assembled to create display devices of various sizes. This segmentation allows a single production line to produce multiple size configurations, improving productivity while maintaining manufacturing precision through modular assembly rather than custom production for each size.
Solution Approach 2:
The active panels and driving panels are designed as universal components that can be used across multiple display device configurations. The standardized interface and connection mechanisms allow the same panel modules to be assembled into different display sizes, enabling a single production process to serve multiple product variants, thus improving productivity without sacrificing manufacturing precision.
2Productivity
If display devices are modularized into active panels and driving panels, then productivity increases through flexible assembly, but device complexity increases due to additional connection components
Solution Approach 1:
The display device is segmented into distinct active panel and driving panel modules with standardized interfaces. This segmentation enables independent manufacturing and flexible assembly, improving productivity. The connection structures are designed as simple, standardized components rather than complex integrated systems, minimizing the increase in device complexity while enabling modular assembly.
3Adaptability or versatility
If connection members are used to couple driving panels with active panels, then adaptability increases for creating different display configurations, but manufacturing precision requirements increase due to alignment demands
Solution Approach 1:
Connection members serve as intermediary components between driving panels and active panels, providing standardized mechanical and electrical interfaces. These intermediaries incorporate alignment features and tolerance compensation mechanisms that reduce the precision demands on the panels themselves. The connection members absorb alignment variations, enabling adaptable configurations while maintaining acceptable manufacturing precision through built-in compensation rather than requiring ultra-precise panel fabrication.

AI summary
A display device includes an active panel including a display area including a plurality of pixels and a non-display area surrounding the display area, the non-display area including an adjacent area adjacent to the display area and bending areas spaced from the display area by the adjacent area, the bending areas including a connection electrode and a first driving panel in contact with a first bending area of the active panel by a first connection member, and electrically coupled to the active panel. Each of the bending areas is bent in a direction perpendicular to a plane formed by the display area, and the active panel includes an opening in the first bending area exposing the connection electrode, and the first connection member is configured to couple a first signal from the first driving panel to the active panel through the connection electrode.
