LCD Common Voltage Line Stacked Interconnection Noise Reduction

The patent applies the 'Blessing in disguise' principle by converting the harmful surface noise generated during crystal orientation into a beneficial effect. The patent introduces a specific crystal orientation (radial orientation) where the c-axis of the crystal aligns with the normal direction of the substrate, and controls the a-axis orientation to be parallel to the rubbing direction. This specific orientation configuration transforms the potentially harmful surface noise into a controlled phenomenon that does not cause malfunction, thereby enabling successful touch panel integration while maintaining display performance

The patent applies the 'Parameter changes' principle by fundamentally changing the crystal orientation parameters to eliminate surface noise issues. Specifically, the patent sets the c-axis orientation perpendicular to the substrate surface and the a-axis orientation parallel to the rubbing direction, which transforms the liquid crystal display device into an ultra-thin and lightweight design without compromising reliability. This parameter change enables the device to achieve both portability and high reliability simultaneously

The patent applies the 'Local quality' principle by introducing a directional quality difference in the crystal orientation. Instead of uniform random orientation, the patent creates a specific local orientation where the a-axis of the crystal aligns parallel to the rubbing direction while the c-axis remains perpendicular to the substrate. This local quality enhancement in crystal orientation eliminates surface noise and ensures touch panel compatibility while maintaining manufacturing feasibility through standard rubbing processes
