Touch Sensing Unit Insulation Patterns for Display Noise Reduction

The patent introduces an intermediate insulation layer positioned between the touch signal lines and other conductive components (such as electrode patterns). This insulation layer acts as a mediator that electrically isolates the signal lines from potential noise sources, allowing touch sensing to function while maintaining signal integrity and reducing electromagnetic interference.

The patent applies insulation patterns selectively in specific regions where noise interference is most likely to occur. Rather than insulating the entire device uniformly, the insulation layers and patterns are strategically placed at critical locations such as where signal lines cross over electrode patterns or pass through high-noise areas, providing targeted noise reduction while maintaining overall device performance.

The patent combines multiple insulation functions into integrated insulation layers that serve both as electrical isolation barriers and as structural support elements. The intermediate insulation layer, for example, simultaneously provides noise reduction and mechanical support for routing touch signal lines, thereby reducing the need for separate dedicated components and simplifying the overall device architecture.

The insulation layers are designed to perform multiple functions: electrical insulation to block noise, mechanical support to maintain layer spacing, and routing guidance for signal lines. By making these layers multi-functional, the patent achieves effective noise reduction without proportionally increasing device complexity, as each layer contributes to multiple aspects of device performance.
