Solution Overview
Problem
Existing display devices face challenges in efficiently producing display devices of varying sizes due to the complexity of the production process, which often requires separate manufacturing steps for different sizes.
Innovation Solution
The display device is modularized by coupling active panels and driving panels using connection members, allowing for the assembly of display devices of various sizes by connecting these panels together.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the production process is divided and operated according to different sizes, then display devices of various sizes can be produced, but the production process becomes complex and less efficient
Solution Approach 1:
The display device is divided into multiple independent modules: active panels, driving panels, and bending areas. Each module can be manufactured separately using standardized processes, then assembled through the bending areas to create display devices of different sizes. This segmentation eliminates the need for completely separate production processes for each size.
Solution Approach 2:
The bending areas serve multiple functions: they act as connection regions between active and driving panels, provide electrical connections through connection electrodes, and enable modular assembly for different display sizes. This universal component allows the same basic modules to be used across multiple product configurations.
2Manufacturing precision
If separate manufacturing steps are used for different sizes, then each size can be optimized, but production efficiency decreases and time is lost
Solution Approach 1:
Standardized active panels and driving panels are manufactured in advance using optimized processes. These pre-manufactured modules are then quickly assembled through the bending areas, eliminating the need to perform separate manufacturing steps for each display size configuration.
Solution Approach 2:
Multiple standardized modules (active panels and driving panels) are nested and connected through bending areas to form larger display devices. This hierarchical assembly allows efficient production where smaller standardized units are combined to create various larger configurations.
3Adaptability or versatility
If multiple driving panels are coupled to active panels through bending areas, then display devices of various sizes can be assembled, but the structure becomes more complex
Solution Approach 1:
Multiple driving panels and active panels are merged through the bending areas, which serve as integrated connection structures. The bending areas combine mechanical support, electrical connection, and structural alignment functions, simplifying the overall assembly despite the multiple components involved.
