Display Terminal Status Indication via Segmented Light Emitting Parts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display apparatuses with multiple input terminals do not clearly indicate which terminal is receiving an image signal, making it difficult for users to determine the source of the displayed image.
Innovation Solution
A display apparatus with multiple input terminals, featuring a first display part that indicates whether each terminal accepts an image signal and a second display part that shows the selected terminal, using light emitting parts and control mechanisms to visually differentiate between active and selected terminals, allowing users to easily identify the signal source.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a display apparatus shows whether input terminals accept image signals, then users can identify available terminals, but users cannot determine which terminal is currently selected and displaying the image
Solution Approach 1:
The display apparatus segments the status indication into two distinct parts: a first display part that shows whether each input terminal accepts image signals, and a second display part that shows which terminal is currently selected. This segmentation allows users to separately understand terminal availability and terminal selection status, resolving the information gap without creating confusion.
Solution Approach 2:
The second display part provides real-time feedback about which input terminal is currently selected and displaying the image. This feedback mechanism complements the first display part by adding the missing information layer, enabling users to immediately know the relationship between the displayed image and its source terminal.
2Illumination intensity
If light emitting parts are used to indicate terminal status, then visibility is improved in dark environments, but power consumption increases
Solution Approach 1:
The light emitting parts are designed to be selectively activated based on environmental conditions or operational modes. By using periodic or conditional illumination rather than continuous lighting, the system maintains visibility in dark environments while minimizing unnecessary power consumption during daylight or when not needed.
3Loss of information
If multiple display parts are added to show terminal status and selection, then information completeness is improved, but device complexity increases
Solution Approach 1:
The first display part and second display part are integrated into a unified control system that manages both terminal status indication and selection display. By merging the control logic and using a coordinated display architecture, the system provides complete information without the complexity of entirely separate indication systems.
Solution Approach 2:
The display parts are designed to serve multiple functions: the first display part not only shows terminal acceptance status but can also work in coordination with the second display part to provide comprehensive terminal information. This multi-functionality reduces the need for additional dedicated components.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables users to clearly recognize which input terminal is receiving the image signal and which is selected, improving user experience by providing visual feedback in both lit and dark environments, while reducing power consumption and preventing information overload.
Implementation Method 1
the first display part has a third display part with respect to each input terminal, the third display part indicates whether or not the input terminal corresponding to the third display part accepts the image signal
Implementation Method 2
the fourth display part is a second light emitting part, and the display apparatus further includes a second light emission control part that lights the second light emitting part when the input terminal corresponding to the second light emitting part is the selected input terminal

AI summary
A display apparatus includes a plurality of input terminals capable of receiving image signals, a first display part showing whether or not the input terminal accepts the image signal with respect to each input terminal of the plurality of input terminals, an image display unit that displays an image according to the image signal received by a selected input terminal selected from the plurality of input terminals on a display surface, and a second display part showing the selected input terminal.
