Multi-Layer Common Electrode Array Substrate for Display Transmittance

The common electrode is divided into multiple independent common electrodes (first common electrode and second common electrode) that are arranged in different film layers. Each common electrode can be independently controlled with different voltages, allowing for optimized electric field distribution that improves transmittance while maintaining manageable device complexity through modular segmentation.

The patent transitions from a single-plane electrode configuration to a multi-layer three-dimensional electrode arrangement. By positioning common electrodes in different film layers (above and below the pixel electrode) and using alternating strip patterns, the system creates multi-dimensional electric fields that enhance LC molecule rotation efficiency and improve transmittance beyond the limitations of conventional single-layer designs.

Multiple common electrodes are merged into a coordinated system where the first and second common electrodes work together with the pixel electrode to generate enhanced multi-dimensional electric fields. The electrodes are positioned in different film layers with alternating strip patterns that interlock spatially, creating a unified electric field distribution that improves transmittance while the integrated design maintains manufacturing feasibility.

The system uses vertical stacking of electrodes in different film layers to add a third dimension to the electrode configuration. This multi-layer arrangement creates overlapping electric field regions that enhance the overall electric field strength and distribution, improving transmittance without requiring excessive horizontal electrode proliferation that would increase complexity.

The common electrode function is segmented across multiple electrodes in different layers, allowing each electrode to contribute specifically to electric field generation. This segmentation enables optimized voltage application to different regions, improving LC molecule rotation efficiency while the segmented structure can be manufactured using standard multi-layer thin-film fabrication processes.

By adding vertical layering to the electrode configuration, the system creates multi-dimensional electric fields that more effectively rotate LC molecules throughout the liquid crystal layer. The alternating strip patterns in different layers generate intersecting electric field lines that enhance rotation efficiency without requiring complex manufacturing steps, as the layered structure follows conventional display manufacturing approaches.
