Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current lamp bank controllers fail to accurately capture display picture content due to mismatched display ratios or sizes, leading to loss of atmosphere and immersion effects, especially with non-full-screen displays or aspect ratios like 21:9, resulting in black edges and poor user experience.
Innovation Solution
A light control method and apparatus based on boundary identification, which acquires video data, identifies invalid edge picture regions, and generates light control signals to match the valid display picture content, synchronizing lamp bank operations with the actual display content by removing black edges and adjusting color data accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the lamp bank controller uses a fixed control mode without boundary identification, then the control system is simple, but the controller cannot accurately capture display picture content when display ratios or sizes mismatch, causing loss of atmosphere and immersion effects
Solution Approach 1:
The system performs preliminary boundary identification on the display picture before generating light control signals. By pre-detecting the valid picture region boundaries and calculating the correspondence relationship between picture pixels and lamp beads in advance, the system ensures accurate capture of display content without requiring complex real-time adjustments during operation.
Solution Approach 2:
The patent introduces a boundary identification module as an intermediary between the video source device and the lamp bank controller. This intermediary component analyzes the display picture to determine valid picture region boundaries and establishes the mapping relationship between picture coordinates and lamp bead coordinates, enabling accurate content capture without directly complicating the core control system.
2Adaptability or versatility
If the controller processes the entire frame picture including black edges, then the processing is simple, but the lamp bank cannot follow the change of valid display picture content, losing atmosphere and immersion effects
Solution Approach 1:
The system applies different processing quality to different regions of the picture. By identifying the valid picture region boundaries, the controller focuses computational resources and control precision only on the relevant content area, while excluding black edge regions. This local quality approach enables adaptability to various display ratios without requiring complex full-frame processing.
Solution Approach 2:
The patent dynamically changes the picture processing parameters based on the identified valid picture region. By adjusting the region of interest, coordinate mapping relationships, and control signal generation parameters according to the actual display content boundaries, the system achieves high adaptability to different display ratios and sizes while maintaining reasonable processing complexity.
3Reliability
If the lamp bank controller does not identify invalid edge regions, then the control process is straightforward, but the lamp bank cannot synchronize with actual display content in non-full-screen displays, resulting in poor user experience
Solution Approach 1:
The system implements a feedback mechanism where the boundary identification module continuously monitors the display picture content and adjusts the valid picture region boundaries accordingly. By using feedback from the actual display content analysis, the system reliably identifies synchronization regions and maintains accurate light-display coordination, overcoming the difficulty of boundary detection through iterative refinement.
