Display Apparatus Object Overlay and State Reproduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display systems face challenges in displaying content that exceeds the display range of the apparatus, often resulting in partial content being cut off, and there is a need to easily reproduce the display state of content data without specifying the displayed range.
Innovation Solution
A display apparatus with a control unit that generates and combines display objects with the primary image, storing both the original and combined image data to allow easy reproduction of display states, including the option to display or hide the objects, and handle content larger than the display surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If content data larger than display range is displayed, then content completeness is improved, but display apparatus cannot show entire content at once
Solution Approach 1:
The content data is divided into multiple pages, with each page representing a manageable segment that fits within the display apparatus's display range. The display apparatus sequentially displays these segmented pages, allowing complete content to be shown through pagination while each individual display remains within the physical constraints of the device.
2Measurement precision
If display state needs to be reproduced, then accuracy is improved, but manual specification of displayed range is required
Solution Approach 1:
The display apparatus creates a digital copy or representation of the display state that includes metadata about the current page and displayed range. This copied state information is stored and can be automatically restored, eliminating the need for manual re-specification of display parameters while maintaining precise reproduction of the original display state.
3Adaptability or versatility
If display objects are combined with primary image, then functionality is improved, but data management complexity increases
Solution Approach 1:
The display object data and primary image data are merged into a single integrated data structure that represents the complete display state. This combined data structure manages both elements together, reducing the complexity of managing separate data streams while enabling versatile display functionality where objects can be overlaid on or combined with the primary content.

AI summary
A display apparatus includes: a display unit that displays a first image on a display surface; a control unit that causes the display unit to display the first image on the display surface; an object processing unit that generates a display object; and a storage unit. The control unit generates a second image by combining the display object generated by the object processing unit with the first image displayed on the display surface, and causes the display unit to display the second image. The storage unit stores first display data which represents the first image displayed on the display unit. The storage unit also stores second display data which represents the second image in association with the first display data.
