Display Device Layer Management for Selective Content Output
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices require users to manually manage and differentiate between content to be stored and printed, and content to be retained or deleted, which is cumbersome and limits user freedom in writing and layer management.
Innovation Solution
A display device with a mode switching unit that allows objects to be disposed in either a standard processing layer for printing or a special processing layer for retention, enabling intuitive selection and movement between layers without conscious consideration of storage and print settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users manually manage and differentiate between content to be stored and printed, then content output control is achieved, but user operation becomes cumbersome and time-consuming
Solution Approach 1:
The patent segments content into different layers (first layer for print content, second layer for non-print content) and assigns different processing rules to each layer. This allows automatic differentiation of content destined for storage/print versus retention only, eliminating the need for users to manually manage each content item's output settings.
Solution Approach 2:
The system performs preliminary classification of content into different layers based on predetermined processing rules before the user completes input. By pre-establishing layer-based processing logic, the system automatically determines which content should be printed and which should be retained, saving user time and effort in content management.
2Quantity of substance
If all input content is stored and printed, then complete record is maintained, but unwanted content is also printed increasing output volume
Solution Approach 1:
The patent divides content into separate layers with different processing destinies. The first layer contains content intended for printing and storage, while the second layer contains content to be retained but not printed. This segmentation enables selective output that reduces printed volume while preserving all input content in appropriate locations.
Solution Approach 2:
The system extracts content that should not be printed from the general input stream and places it in a separate second layer. This extraction mechanism allows unwanted content to be isolated and excluded from print output while still being preserved in the system for future reference if needed.
3Ease of operation
If layer-based processing is implemented, then selective print control is achieved, but user awareness of current layer becomes necessary increasing cognitive load
Solution Approach 1:
The system automatically tracks and manages the current layer state without requiring user intervention. The layer switching and content routing occur automatically based on the system's internal state management, freeing the user from needing to consciously track which layer is active while still benefiting from layer-based processing.
4Ease of operation
If region-based input restriction is applied, then input organization is improved, but writing freedom decreases
Solution Approach 1:
Instead of restricting input to specific spatial regions on the display, the patent introduces a new dimensional approach by using temporal/logical layers. Users can input content freely in any spatial location, and the system automatically routes content to appropriate layers based on processing rules, thereby maintaining writing freedom while achieving input organization.

AI summary
A display device includes a display unit that displays an object disposed in a layer on a display screen, an output unit that outputs the object, a mode switching unit that switches a mode between a first mode and a second mode, and an object disposing unit that disposes an object in a first layer when the mode is the first mode and disposes an object in a second layer when the mode is the second mode. The display unit displays the objects disposed in the first layer and the second layer. The output unit outputs the object disposed in the first layer.
