Multi-display layout adjustment via signal detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current multi-display systems require manual adjustment of display layouts in response to changes in the number of video signals, resolution, and viewer positions, making them inflexible and costly for applications like conference tables.
Innovation Solution
A multi-display system with a receiving unit, display layout determining unit, and display unit that automatically adjusts the layout based on the number of input video signals, resolution, and viewer positions, using a combination of sensors and look-up tables to dynamically allocate video signals and adjust magnification and display areas across multiple display devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual determination of display layout is used, then display configuration can be precisely controlled, but operation complexity increases and flexibility decreases when video conditions change
Solution Approach 1:
The system automatically determines display layout based on the number of video signals input and detected viewer positions, eliminating the need for manual configuration. The control unit self-adjusts the display layout by referencing stored layout information corresponding to different video signal conditions and sensor inputs.
Solution Approach 2:
The display layout is made dynamic and adaptable to changing conditions. The system stores multiple display layout configurations and automatically selects appropriate layouts based on real-time detection of video signal count and viewer positions, enabling flexible adaptation without manual intervention.
2Area of stationary object
If a large display device is used as a conference table, then display size is sufficient, but cost increases significantly
Solution Approach 1:
Instead of using one large expensive display device, the system segments the display function across multiple smaller, more affordable display devices. These multiple displays are arranged to form a conference table configuration, achieving the required total display area while reducing individual device costs and overall system expense.
Solution Approach 2:
Multiple separate display devices are merged to function collectively as a conference table display system. The control unit coordinates these individual displays to present unified or divided content based on viewer positions, creating the functional equivalent of a large display table at lower cost.
3Manufacturing precision
If display layout is manually changed for each participant change, then display accuracy is maintained, but time consumption increases
Solution Approach 1:
Multiple display layout configurations are predetermined and stored in the control unit before actual use. When participants are detected by sensors, the system quickly retrieves and applies the pre-prepared layout information corresponding to the detected participant count and positions, avoiding time-consuming manual adjustments while maintaining accurate display configuration.
4Adaptability or versatility
If multi-display system is used as conference table, then flexibility is improved, but difficulty in changing display layout automatically increases
Solution Approach 1:
The system incorporates sensors that detect participant positions and feed this information back to the control unit. Based on this feedback, the control unit automatically selects and applies appropriate display layout configurations from stored options, enabling flexible adaptation to different meeting scenarios through an automated feedback-driven process.

AI summary
A multi-display system provided with display devices arranged to form a rectangular video display screen as a whole includes: distributors to which video signals are input; CPUs for detecting the number of input video signals; arrangement determining units for determining a display layout on the video display screen by looking-up a pre-set look-up table using the number of input video signals detected by the CPUs; and display units for displaying an input video image or images on the video display screen, in accordance with the determined display layout and the arrangement of display devices. Thus, the display layout of the multi-display system can automatically be changed in accordance with external environment.
