Image Display Apparatus Channel Interchange Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image display apparatuses for multiple channels on a single screen face operability issues when selecting channels, as the display area per channel is reduced, and users must perform cumbersome operations to return to previously viewed channels after interchanging them between main and sub display areas.
Innovation Solution
An image display apparatus with a main and sub display area, where the control unit manages channel interchanges to maintain the original channel's display position in the sub area, preventing it from being replaced when moving to subsequent pages, and allowing easy return to previously viewed channels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If images of multiple channels are displayed in a single screen with reduced size, then the display area per channel is reduced, but it enables viewing multiple channels simultaneously
Solution Approach 1:
The display screen is segmented into a main display area for the currently selected channel and a sub display area for displaying thumbnails of other available channels. This segmentation allows users to view multiple channels simultaneously while maintaining a large display area for the active channel, resolving the contradiction between displaying multiple channels and maintaining adequate display area per channel.
2Area of moving object
If the sub display area is limited to a small area, then the main display area can be enlarged, but users must open following pages to view all channels
Solution Approach 1:
The system performs preliminary action by automatically preventing the channel that was previously displayed in the main display area from being replaced in the sub display area after an interchange operation. This preliminary protection ensures that the recently viewed channel remains accessible in the sub display area without requiring users to navigate to following pages, thus maintaining ease of operation while preserving a large main display area.
3Adaptability or versatility
If a channel previously displayed in the main display area is allowed to be replaced in the sub display area, then the sub display area can show new channels, but the user loses access to the previously viewed channel
Solution Approach 1:
The system implements feedback by monitoring interchange operations between main and sub display areas and automatically adjusting the sub display area content accordingly. When a channel interchange occurs, the system provides feedback by preserving the previously displayed channel in the sub display area, ensuring continuous accessibility to recently viewed channels while still allowing the sub display area to show other available channels.

AI summary
An image display apparatus includes: a display unit having a main display area for displaying an image of a main channel and a sub display area for displaying images of channels which can be interchanged with the image of the main channel in the main display area; a replacement unit for replacing the images of the channels displayed in the sub display area with images of other channels not displayed in the sub display area; and a control unit which, after an operation to interchange images of channels in the main and sub display areas is performed with the image of the channel displayed in the main display area as an interchange source, controls to prevent the image of the interchange source channel previously displayed in the main display area which after the interchange is displayed in the sub display area from being a replacing target of the replacement unit.
