Horizontal Field LCD Multi-Electrode Segmentation

The common electrode is divided into multiple segments (first common electrode, second common electrode, third common electrode) arranged in different layers. This segmentation allows the electrical field to be applied more uniformly and effectively to the liquid crystal material across different regions and depths, resolving the insufficient electrical field application while maintaining reasonable device complexity.

The patent introduces a multi-layer electrode structure where electrodes are arranged not only in the plane but also in the vertical dimension. The first common electrode is in the same layer as the gate electrode, while the second and third common electrodes are in different layers, creating a three-dimensional electrical field distribution that improves liquid crystal control.

The multiple common electrodes (first, second, and third) are electrically connected to serve a unified function of controlling the liquid crystal material. This multi-functional design allows the electrode system to provide comprehensive electrical field coverage while being controlled through a coordinated potential difference application, balancing improved reliability with managed complexity.

The patent combines multiple common electrodes into a coordinated system where the first common electrode is in the same layer as the gate electrode, and the second and third common electrodes are in different layers but electrically connected. This merging of multiple electrodes into a unified control system achieves better electrical field application while preventing excessive complexity through integrated control.

The patent applies different electrode configurations to different spatial regions and layers. The first common electrode is positioned in the same layer as the gate electrode, while the second and third common electrodes are in different layers, creating localized electrical field distributions that optimize both viewing angle and color consistency across different observation angles.

The multi-layer electrode structure creates a composite electrical field environment that simultaneously achieves wide viewing angle characteristics and minimizes color-shift. The combination of electrodes in different layers with coordinated potential differences produces a composite effect that resolves the trade-off between viewing angle and color accuracy.
