Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If conventional splicing technology is used for large-size OLED displays, then large display size can be achieved, but frame size becomes large and process complexity increases
Solution Approach 1:
The display panel is divided into multiple independent display components (first display component, second display component, etc.) that can be separately manufactured and then spliced together. Each display component has its own connection terminals that interface with the driving backplane, enabling modular assembly that simplifies the overall manufacturing process while achieving large display sizes
Solution Approach 2:
The driving backplane serves multiple functions: it provides the driving circuit layer for controlling display components, contains connection terminals for electrical connection, and acts as a substrate for mounting multiple display components. This multi-functionality reduces the need for separate components and simplifies the overall structure
2Area of stationary object
If conventional splicing technology is used for large-size OLED displays, then large display size can be achieved, but frame size becomes large
Solution Approach 1:
The connection terminals of adjacent display components are bound together and integrated with the driving backplane connection terminals. This merging of connection structures eliminates the need for separate frame structures to hold and connect components, reducing frame size while maintaining structural integrity
Solution Approach 2:
The connection terminals extend in multiple directions (first direction and second direction) from the display components to the driving backplane, utilizing two-dimensional spatial arrangement rather than linear connection. This allows for compact integration and reduced frame dimensions
3Area of stationary object
If conventional splicing technology is used for large-size OLED displays, then large display size can be achieved, but manufacturing difficulty increases
Solution Approach 1:
The connection terminals are pre-formed on each display component during the component manufacturing process, and the driving backplane is prepared with corresponding connection structures before final assembly. This preliminary preparation of connection interfaces simplifies the splicing process and reduces manufacturing difficulty
Solution Approach 2:
The driving backplane acts as an intermediary structure that interfaces between multiple display components and the driving integrated circuit. It provides a standardized connection interface that simplifies the coupling of components and reduces the complexity of direct component-to-component connections
