1Reliability
If a connector and conductive adhesive are used to conduct the array substrate and color filter substrate, then electrical conduction is achieved, but the device complexity and production cost increase
Solution Approach 1:
The patent merges the conduction function into the existing color filter layers and metal layers, eliminating the need for separate connectors and conductive adhesives. The color filter layers are configured to conduct electrical signals between the array substrate and color filter substrate, while metal layers provide additional conduction paths, thereby simplifying the overall conduction structure.
Solution Approach 2:
The color filter layers serve dual functions: optical filtering and electrical conduction. By making the color filter layers conductive, the patent eliminates the need for separate conductive components, reducing device complexity while maintaining reliable electrical connection between substrates.
2Reliability
If a connector and conductive adhesive are used to conduct the array substrate and color filter substrate, then electrical conduction is achieved, but the production cost increases
Solution Approach 1:
The patent combines multiple functions into existing layers to eliminate additional materials and manufacturing steps. The color filter layers are made conductive to replace both optical filters and conductive adhesives, while metal layers provide structural support and additional conduction, reducing material costs and simplifying the manufacturing process.
Solution Approach 2:
The patent eliminates the need for separate conductive adhesives and connectors by recovering and utilizing the conduction capability within the existing color filter and metal layers, thereby reducing material costs and simplifying the manufacturing process.
3Reliability
