Display Panel Non-Linear Signal Routing for Moire Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Grating-type 3D display devices face issues with moire formation, which affects the 3D display effect due to the overlapping regions of light-emitting regions and signal routing wires on the display panel.
Innovation Solution
The display panel design includes a base substrate with sub-pixels and signal routing wires, where the overlapping regions between the orthographic projections of the light-emitting regions and signal routing wires are non-linear, specifically in a broken line shape with a bending angle greater than or equal to 70° and less than 180°, allowing for light interference that improves the 3D display effect by reducing moire.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If signal routing wires are placed in overlapping regions with light-emitting regions, then manufacturing is simplified, but moire is formed affecting display quality
Solution Approach 1:
The patent applies curvature by designing the signal routing wires to follow a curved path through the overlapping region rather than a straight line. Specifically, the wire forms an arc with a predetermined radius of curvature, which disrupts the regular interference pattern that causes moire while still allowing the wire to pass through the overlapping region between the light-emitting regions.
Solution Approach 2:
The patent changes the geometric parameters of the signal routing wire by defining its path using specific mathematical relationships. The wire's position is determined by equations involving the radius of curvature and angular parameters, transforming the wire from a straight linear path to a curved path that avoids moire formation while maintaining electrical connectivity.
2Device complexity
If straight signal routing wires are used in overlapping regions, then device complexity is reduced, but light interference patterns deteriorate causing moire
Solution Approach 1:
The patent introduces curvature to the signal routing wire path, transforming it from a straight line to an arc. This curved configuration changes how light interacts with the wire in the overlapping region, creating a more favorable interference pattern that reduces moire while maintaining acceptable device complexity through systematic geometric design.
3Manufacturing precision
If signal routing wires overlap with light-emitting regions, then manufacturing precision requirements are relaxed, but display quality deteriorates due to moire
Solution Approach 1:
By designing the signal routing wire with a curved path characterized by a specific radius of curvature, the patent creates a configuration that is more robust to manufacturing variations. The curved path distributes the wire's presence across multiple positions in the overlapping region, reducing sensitivity to precise positioning while maintaining optimal light interference characteristics that minimize moire.
