Stretchable Transparent Conductor for Vehicle Lighting Heaters

The patent divides the conductive layer into a network pattern of thin conductive lines rather than a continuous thick layer. This segmentation maintains electrical conductivity through the interconnected network while preserving light transmittance in the spaces between the lines, resolving the contradiction between conductivity and light transmission.

The patent uses composite materials by combining transparent conductive materials (such as ITO, IZO, or FTO) with transparent resin materials in a layered structure. This composite approach allows the conductive layer to achieve low resistance through the network pattern while the transparent resin maintains overall light transmittance and provides mechanical flexibility.

The patent replaces complex vapor deposition or sputtering processes with simpler coating methods such as solution coating, spray coating, or printing techniques. This substitution maintains conductivity by depositing conductive material in a network pattern while dramatically improving productivity and reducing material loss through more efficient deposition processes.

The patent changes the formation parameters by using lower temperature processing and simpler deposition methods instead of high-energy vapor deposition. This allows the conductive network to be formed with standard coating equipment, improving productivity while maintaining the required electrical conductivity through optimized network density and material composition.

The patent merges the conductive network formation with the transparent electrode layer deposition into a single integrated process. The conductive network is formed directly on the transparent substrate in one coating or printing step, eliminating the need for separate busline formation processes and reducing overall device complexity while maintaining conductivity.

The patent creates a multi-functional transparent electrode layer that simultaneously provides both the transparent conductive function and the conductive network function. This universal layer eliminates the need for separate conductive buslines and additional processing steps, reducing device complexity and manufacturing cost while maintaining electrical conductivity.

The patent uses thin film conductive materials arranged in a network pattern instead of thick wires. This thin film approach maintains heat generation capability through the distributed network structure while preserving visibility and transparency, as the thin conductive lines and spaces between them allow light to pass through effectively.

The patent segments the conductive material into a network of thin lines rather than using continuous thick wires. This segmentation maintains the total conductive cross-section for heat generation while creating transparent spaces between the lines that preserve visibility, resolving the contradiction between heat generation capability and visibility.
