Asymmetric TFT Pixel Structure for LCD Striation Elimination

The patent applies asymmetry by intentionally designing different connection configurations for odd and even rows. Specifically, pixel units in odd rows are connected to data lines on the left side, while pixel units in even rows are connected to data lines on the right side. This asymmetric design compensates for the manufacturing alignment errors that cause unequal capacitance, allowing the common electrode to effectively compensate voltages and eliminate transverse striations and flicker while maintaining low power consumption through column inversion.

The patent segments the pixel array into odd rows and even rows with different connection patterns. By dividing the display into two groups with asymmetric connections, the patent achieves dot inversion effect (improving display quality) while using column inversion methodology (reducing power consumption). This segmentation allows each row type to be optimized independently, resolving the contradiction between display quality and power consumption.

Instead of trying to achieve precise alignment to ensure equal capacitance (traditional approach), the patent inverts the problem by intentionally designing different connection configurations for odd and even rows. This inversion approach accepts the alignment variations and compensates through asymmetric design, thereby reducing manufacturing complexity while maintaining display quality.
