Multi-tiling Display Synchronization via Dynamic Scan Direction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In multi-tiling image display systems, misalignment occurs between image display devices when displaying moving images, as the vertical display lines are not synchronized, leading to delayed data display across adjacent devices.
Innovation Solution
An image display system with detection and signal control units that adjust the vertical display direction and image data transmission order of each device to synchronize the display lines, using position information signals to ensure proper alignment, allowing odd-numbered devices to display from top to bottom and even-numbered devices from bottom to top.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple image display devices are arranged vertically in multi-tiling configuration, then the display area is increased, but misalignment occurs at the interfaces between adjacent devices
Solution Approach 1:
The patent applies dynamics by making the vertical display direction adjustable rather than fixed. Each image display device can dynamically switch between top-to-bottom and bottom-to-top display directions based on its position in the multi-tiling arrangement. This dynamic adaptation allows the system to maintain proper alignment at interfaces while preserving the increased display area benefit of vertical multi-tiling.
2Device complexity
If image data is transmitted in fixed sequential order from top to bottom, then the data transmission process is simple, but misalignment occurs at device interfaces
Solution Approach 1:
The patent applies inversion by reversing the data transmission order for specific devices in the multi-tiling arrangement. Instead of all devices transmitting data in the same top-to-bottom sequence, devices at even positions transmit data in bottom-to-top order. This inverted transmission approach for certain devices eliminates interface misalignment while maintaining relatively simple transmission logic.
