Multi-display Misalignment Correction via Line Start Signal Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional multi-display systems lack effective techniques to manage misalignments that may occur across multiple displays, particularly due to differences in physical dimensions and screen resolutions, leading to imperfect alignment of displayed information.
Innovation Solution
The system identifies misalignment between displays and adjusts the line start position by transmitting a first line start signal at a modified position to correct the misalignment, using a processor and memory to determine the necessary adjustments and implement changes, such as inserting dummy pixels to align images across multiple displays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple displays with different physical dimensions and screen resolutions are used to increase display capacity and versatility, then the system can show more information concurrently, but misalignment and pixel mismatch occur across the displays
Solution Approach 1:
The patent changes the timing parameters of display signal transmission by adjusting the horizontal sync start position and inserting dummy pixels. This modifies when pixel data is sent to each display device, compensating for physical misalignment differences between displays with varying resolutions and dimensions, thereby maintaining visual continuity across the multi-display system
Solution Approach 2:
The system performs preliminary detection of misalignment between displays and pre-calculates the necessary timing adjustments and dummy pixel insertions before actual display content is rendered. This advance preparation ensures that alignment corrections are already in place when content is displayed, preventing visual discontinuities without requiring real-time adjustments
2Adaptability or versatility
If displays are physically mounted with tolerances to achieve multi-display configuration, then system versatility is improved, but mechanical tolerance causes pixel misalignment and visual discontinuity
Solution Approach 1:
The patent introduces dummy pixels as an intermediary element between the content source and the display devices. These dummy pixels act as a buffer that absorbs the timing differences caused by mechanical mounting tolerances, allowing displays with different physical dimensions and resolutions to be synchronized visually without requiring precise mechanical alignment
Solution Approach 2:
The system adjusts the horizontal synchronization timing parameters for each display device based on its specific physical characteristics and position. By dynamically changing the sync start position and inserting varying numbers of dummy pixels for different displays, the system compensates for mechanical tolerances and achieves visual continuity across physically diverse display devices
