Display Panel Segmented Scanning for 3D Crosstalk Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Large-size display panels using the SG 3D technique face issues with low brightness and high 3D crosstalk due to increased wire impedance and reduced charging time for pixels, leading to insufficient charging rates.
Innovation Solution
The display panel is divided into multiple regions, allowing simultaneous scanning of these regions, which reduces wire impedance and increases the charging rate by altering the scanning direction of data and gate lines between adjacent regions, thereby improving the 3D display effect.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the display panel uses row-by-row and column-by-column scanning manner, then the scanning process is simple and sequential, but the wire impedance of lines increases and charging time for pixels increases, resulting in low brightness and insufficient charging rate for large-size panels
Solution Approach 1:
The display panel is divided into multiple scanning zones (e.g., first scanning zone and second scanning zone) with different scanning directions. This segmentation allows parallel scanning operations in different zones, reducing the overall scanning time and increasing the charging rate for pixels, thereby resolving the contradiction between simple scanning process and insufficient charging rate.
2Ease of operation
If the display panel uses row-by-row and column-by-column scanning manner, then the scanning sequence is straightforward, but the effective charging time for a single row of pixels is considerably reduced, leading to low brightness
Solution Approach 1:
The display panel is divided into multiple scanning zones with different scanning directions. This allows different regions to be scanned simultaneously in parallel, effectively increasing the total charging time available for pixels and thereby improving brightness, while maintaining operational simplicity through systematic zone management.
Solution Approach 2:
Adjacent scanning zones use opposite scanning directions (e.g., one zone scans from top to bottom while the adjacent zone scans from bottom to top). This inversion of scanning direction enables parallel scanning operations that increase effective charging time for pixels, thereby improving brightness without complicating the overall scanning sequence.
3Device complexity
If the display panel uses traditional scanning method, then the control circuit is simple, but the 3D crosstalk is large and various picture problems occur due to insufficient charging rate
Solution Approach 1:
The display panel is segmented into multiple scanning zones with different scanning directions, enabling parallel scanning that increases pixel charging rate. This improvement in charging rate reduces 3D crosstalk and eliminates picture problems, thereby enhancing 3D display quality without requiring complex control circuits.
Solution Approach 2:
The scanning system dynamically adjusts scanning directions in different zones rather than using a fixed uniform scanning pattern. This dynamic approach increases charging efficiency and reduces crosstalk, improving 3D display reliability while keeping the control circuit relatively simple through adaptive scanning control.
