Display Control Method for Multi-Projector Area Division
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The operation of setting utilization forms for multiple display devices is cumbersome for users, as existing methods do not efficiently manage the division and assignment of display areas for multiple video outputs from video output devices.
Innovation Solution
A display control method that includes a system with video output devices and display devices, where the display area is divided into sub-areas and videos are assigned to each sub-area based on the number of videos and display devices, allowing for efficient video display without requiring user intervention in complex settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple display devices are used with manual configuration, then video display capability is improved, but operation complexity increases
Solution Approach 1:
The display system automatically detects the number of connected display devices and self-configures the display areas without requiring manual user input. The controller autonomously divides the display areas and assigns videos based on the detected device count, making the system self-configure and eliminating complex manual setup operations.
Solution Approach 2:
The system performs automatic detection and configuration actions before the user needs to use the display devices. By pre-configuring the display areas and video assignments based on automatic device detection, the system prepares the multi-device environment in advance, eliminating the need for users to perform complex setup procedures.
2Manufacturing precision
If display areas are manually divided and assigned, then video assignment precision is improved, but time consumption increases
Solution Approach 1:
The controller automatically detects the number of display devices and self-performs the division and assignment of display areas. This self-service mechanism ensures precise video assignment to appropriate display devices while eliminating the time users would otherwise spend on manual configuration, achieving both precision and efficiency simultaneously.
Solution Approach 2:
The system performs the division and assignment of display areas as a preliminary automatic action before video playback begins. By pre-configuring the display area division and video assignment based on automatic device detection, the system ensures precise allocation without requiring users to spend time on manual setup procedures.
3Ease of operation
If automatic video assignment is implemented, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The controller is designed with multi-functionality, integrating both the automatic detection of display devices and the division/assignment of display areas into a single control unit. This universal controller handles multiple tasks (detection, division, assignment) that would otherwise require separate components, achieving automatic video assignment while minimizing the increase in overall system complexity.

AI summary
A display control method includes outputting, by at least one video output device, M videos, M being an integer larger than or equal to 1, if M<N, displaying the M videos in each of M sub-areas by respectively assigning each of the M videos to each of the M sub-areas obtained by dividing a single large area in which an image is displayed by N display devices, N being an integer larger than or equal to 2, and if M=N, displaying each of the M videos by assigning each of the M videos to each of N display areas corresponding to the N display devices respectively.
