Display Panel Data Line Segmentation for Power and Color Shift

The patent segments the data transmission function by creating separate data lines for different color sub-pixels. Instead of one data line serving all colors (R, G, B), multiple data lines are introduced where each line is dedicated to specific color groups. This segmentation reduces the switching frequency and signal complexity for each data line, thereby reducing power consumption in the source driving circuit while maintaining full-color display capability.

The patent applies local quality by assigning different data lines to different spatial regions or color groups. Specifically, first data lines are used for red and green sub-pixels while second data lines are used for blue and green sub-pixels. This localized assignment optimizes the electrical characteristics for each color group and reduces the overall power consumption by avoiding the need for a single high-power data line to handle all color transitions.

By segmenting data transmission into separate channels for different color groups, the patent eliminates the color shift problem that occurs when a single data line must rapidly switch between different color signals at high frequencies. Each data line operates at a lower, more stable frequency for its assigned color group, ensuring accurate color reproduction even in high-frequency display modes.

The patent ensures color accuracy by assigning specific data lines to specific color sub-pixels (first data lines for R and G, second data lines for B and G). This localized signal path ensures that each color receives its data signal through an optimized channel, preventing the color shift that would occur if different colors shared a common data line with varying signal characteristics.
