Display Panel Pixel Layout for Crosstalk and Aperture Ratio
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The 1G1D pixel driving architecture in display panels suffers from low aperture ratio, low transmittance, and excessive chromaticity change due to crosstalk factors, particularly when displaying color images.
Innovation Solution
The display panel is redesigned with sub-pixel groups comprising multiple columns, data line groups with alternating polarities, and a cross-shaped pixel electrode structure, eliminating the need for a shielding electrode above data lines.

Engineering Contradiction Analysis
1Object-affected harmful factors
If a shielding electrode is provided above the data line in the 1G1D pixel driving architecture, then crosstalk is reduced, but the aperture ratio of the pixel is low and the transmittance of the display panel is low
Solution Approach 1:
The patent extracts and removes the shielding electrode structure from above the data lines, eliminating the component that was causing the aperture ratio reduction. This is achieved by redesigning the pixel driving architecture to not require shielding electrodes, thereby extracting the harmful element while maintaining crosstalk control through alternative means.
Solution Approach 2:
The patent segments the data line structure by dividing it into multiple data lines within each data line group, arranged in specific patterns. This segmentation allows for reduced crosstalk through spatial distribution while eliminating the need for shielding electrodes, thus improving aperture ratio without sacrificing crosstalk control.
2Object-affected harmful factors
If a shielding electrode is provided above the data line in the 1G1D pixel driving architecture, then crosstalk is reduced, but the transmittance of the display panel is low
Solution Approach 1:
The patent removes the shielding electrode structure that was blocking light transmission, thereby extracting the harmful element that reduced transmittance. The redesigned architecture achieves crosstalk control without requiring the light-blocking shielding electrode, thus improving panel transmittance.
3Device complexity
If the 1G1D pixel driving architecture is used, then the display panel can be manufactured with simpler structure, but the chromaticity change exceeds predefined value when displaying color images
Solution Approach 1:
The patent segments the data line structure into multiple data lines per data line group, with specific arrangements that reduce crosstalk. This segmentation approach maintains relatively simple manufacturing processes while improving chromaticity control by distributing the electrical signals across multiple lines, thereby reducing the harmful electromagnetic interference that causes chromaticity shifts.
Solution Approach 2:
The patent applies different arrangements and configurations to different data lines within each data line group, optimizing the local electrical characteristics to minimize crosstalk. This local quality approach allows for improved chromaticity control in specific areas without requiring complete redesign of the entire display structure.
4Area of moving object
If data lines are arranged on one column of sub-pixel units, then the aperture ratio is increased, but crosstalk between adjacent data lines increases
Solution Approach 1:
The patent segments each data line into multiple data lines within a data line group, arranged in specific patterns on the sub-pixel units. This segmentation reduces the current density on each individual line, thereby reducing crosstalk while maintaining the aperture ratio benefits of having data lines positioned on sub-pixel columns.
Solution Approach 2:
The patent employs asymmetric arrangements of data lines within data line groups, where adjacent data lines have different polarities or configurations. This asymmetry creates opposing electromagnetic fields that cancel each other out, reducing crosstalk between adjacent lines while allowing the data lines to be positioned for optimal aperture ratio.
