Display Panel Stem and Branch Electrode Multi-Domain Structure

The pixel electrode is segmented into multiple independent electrode regions (first electrode region, second electrode region, third electrode region, fourth electrode region) that can be independently controlled. This segmentation allows creation of multiple liquid crystal domains within the pixel without requiring additional transistors, as adjacent regions share common electrode connections. The segmentation enables achieving 4-domain or more multi-domain structures while maintaining high aperture ratios.

The common electrode structure serves multiple functions simultaneously: it acts as a driving electrode for multiple adjacent electrode regions, provides reference potential for voltage application, and enables independent control of different liquid crystal domains. This multi-functionality allows the same electrode structure to control multiple domains without increasing device complexity or reducing aperture ratio.

The pixel electrode is divided into multiple independently controllable electrode regions with different voltage phases. By applying different voltages to adjacent regions, the liquid crystal orientation is segmented into different domains, which eliminates the uniform orientation that causes dark stripe areas in conventional PSVA displays while maintaining high contrast and fast response characteristics.

Instead of using a single uniform voltage across the pixel as in conventional PSVA, the invention applies inverted or complementary voltage patterns to different electrode regions. This voltage inversion creates opposing liquid crystal orientations in adjacent domains, which prevents the formation of dark stripe areas while preserving the high contrast and quick response benefits of PSVA technology.
