1Length of moving object
If traditional insulating layers are used between the transistor array layer and electrode layers, then insulation performance is maintained, but the display panel thickness and weight increase
Solution Approach 1:
The patent changes the material parameter of the insulating layer from traditional organic materials to inorganic insulating layers, which have different physical properties including thinner achievable thickness while maintaining or improving insulation performance. This material parameter change enables reduced panel thickness without sacrificing insulation reliability.
Solution Approach 2:
The patent employs composite material structures by combining inorganic insulating layers with the existing transistor array and electrode layer architecture. The inorganic insulating layers are integrated into the multi-layer structure, creating a composite system that achieves both thinness and effective insulation through material composition optimization.
2Object-affected harmful factors
If complex insulating structures are used to reduce interference, then signal interference is reduced, but preparation costs and manufacturing complexity increase
Solution Approach 1:
The patent extracts the insulating function from complex multi-layer organic insulating structures and concentrates it into dedicated inorganic insulating layers positioned strategically between the transistor array layer and electrode layers. This extraction simplifies the overall structure by removing unnecessary complex layers while maintaining the essential insulation function, thereby reducing manufacturing complexity and cost.
Solution Approach 2:
The inorganic insulating layers serve as intermediary elements between the transistor array layer and the electrode layers, providing effective electrical insulation and signal interference reduction. These intermediary layers act as mediators that block harmful electromagnetic coupling while maintaining a simple, cost-effective structure compared to complex alternative designs.
