Organic Conductive Polymer Array Substrate for Flexible Displays

The patent changes the material parameter of the active layer from low-temperature polysilicon to organic conductive polymer material. This material substitution fundamentally alters the mechanical properties of the substrate, enabling flexibility while maintaining transistor functionality. The organic material's inherent flexibility overrides the rigidity constraint of polysilicon, resolving the contradiction between performance and flexibility.

The patent employs composite material structures, specifically using organic conductive polymer materials combined with various insulating layers and electrode materials. This composite approach allows the active layer to provide both electrical performance and mechanical flexibility, while other layers contribute their specialized properties, collectively resolving the contradiction between transistor performance and substrate flexibility.

The patent utilizes multi-layer stacking architecture, arranging transistors, insulating layers, and electrodes in vertical dimensions. This dimensional organization allows compact integration of multiple components within a reduced planar footprint, increasing aperture ratio while managing complexity through systematic layering rather than chaotic miniaturization.

The patent divides the array substrate into distinct functional layers, including first insulating layers, second insulating layers, active layers, and electrode layers. Each layer performs a specific function and can be manufactured independently through sequential processing steps. This segmentation enables precise control of each component while simplifying the overall manufacturing process despite the reduced device size.
