Display Control Apparatus for Multi-Signal Daisy Chaining
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display apparatuses fail to meet the increasingly diverse display requirements in offices and education settings where multiple screens are used to display different signal sources.
Innovation Solution
A display control method and apparatus that allows for controlling image signals to be output on a single display apparatus in different display areas or on multiple connected display apparatuses based on configuration information, enabling flexible display modes such as daisy chaining or split-screen arrangements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple display apparatuses are connected to display different signal sources, then display versatility is improved, but system complexity increases
Solution Approach 1:
The patent merges the functions of multiple display apparatuses into a unified system where a first display apparatus can display content from a first signal source while a second display apparatus displays content from a second signal source. The system integrates signal source selection, display area determination, and content distribution into a coordinated framework, allowing multiple displays to work together as a unified system rather than independent devices.
Solution Approach 2:
The first display apparatus is designed to perform multiple functions: it can display content from the first signal source in a first display area, simultaneously transmit the second signal source to the second display apparatus, and coordinate with the second display apparatus to create a unified multi-display system. This multi-functionality allows a single apparatus to serve as both a primary display and a distribution hub.
2Adaptability or versatility
If a single display apparatus displays multiple image signals in different display areas, then display flexibility is improved, but display area utilization is reduced
Solution Approach 1:
The patent segments the display system into distinct display areas on the first display apparatus, where a first display area is dedicated to displaying the first image signal and a second display area can display the second image signal. This segmentation allows different signal sources to be displayed in separate, non-overlapping regions, optimizing the use of available display area while maintaining flexibility in content distribution.
Solution Approach 2:
The patent extends the display system from a single-dimensional (one display) to a multi-dimensional configuration by utilizing both the first display apparatus and the second display apparatus. This dimensional expansion allows the system to display multiple image signals simultaneously without compromising the display area utilization of each individual apparatus, as the second display apparatus provides an additional spatial dimension for content display.

AI summary
A display apparatus includes a display device, a first interface configured to be connected to an electronic apparatus, a second interface configured to be connected to another display apparatus, a switch device connected to the second interface, and a processor connected to the first interface and the switch device, and configured to obtain an image signal from the electronic apparatus through the first interface. The image signal includes at least a first image signal and a second image signal. The processor is further configured to, in response to the display apparatus being in a first display mode, control the first image signal to be output and displayed on the display device, and transmit the second image signal to the switch device, and in response to the display apparatus being in a second display mode, transmit the second image signal to the switch device.
