Multi-Screen Display Adjusting System with Independent Signal Paths
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-screen display technologies face challenges in efficiently performing image adjustments of displayed videos due to inefficient data reading and composition processes, leading to suboptimal image adjustment capabilities.
Innovation Solution
A multi-screen display system with independent signal paths for each video input, including video input processing units for blanking, color adjustment, and scaler units for size adjustment, along with a screen composing unit and frame memory for determining and storing screen arrangements, and a control unit for managing the signal paths and video output processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If data is read from multiple independent memories instead of a single memory with arranged data, then the composition process can be simplified, but image adjustment capability deteriorates
Solution Approach 1:
The patent divides the video processing system into multiple independent signal paths, each handling a specific video input with its own set of processing units. This segmentation allows each path to independently adjust image parameters while maintaining overall system organization, resolving the contradiction between simplified composition and adjustable image quality.
Solution Approach 2:
The patent performs image adjustments (contrast, brightness, color) and size adjustments in advance within each signal path before the composition process. This preliminary action ensures that image quality is optimized before screens are composed, eliminating the need for complex post-composition adjustments while maintaining image adjustment capability.
2Ease of operation
If independent signal paths with separate processing units are used for each video input, then image adjustment capability is improved, but device complexity increases
Solution Approach 1:
The patent uses identical copies of processing units (video input processing units, color adjusting units, scaler units) for each signal path. This copying approach allows independent image adjustment for each video input while maintaining consistent processing capabilities across all paths, reducing the complexity burden by using standardized modules.
Solution Approach 2:
The patent makes the signal path configuration dynamic and adaptable, allowing the system to flexibly handle different video inputs and adjustment requirements. Each signal path can be independently configured and adjusted based on specific needs, enabling the system to optimize performance without permanent complex wiring.

AI summary
A multi-screen display adjusting system including: a first signal path to which a first video input signal is input and a second signal path to which a second video input signal is input that are independent from each other; a display panel configured to display a first image based on the first video input signal and a second image based on the second video input signal; a screen composing unit configured to determine an arrangement of the first screen and an arrangement of the second screen on the display panel on the basis of an output from the first signal path and an output from the second signal path; a frame memory unit configured to store data of the arrangement of the first screen and data of the arrangement of the second screen; a video output processing unit configured to read the data of the arrangement of the first screen from the frame memory unit and generate a first signal timing for displaying the first screen and read the data of the arrangement of the second screen from the frame memory unit and generate a second signal timing for displaying the second screen; and a control unit.
