Display Control Device Preventing Duplicate Screen Types
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display control devices fail to prevent identical display types from being shown on multiple screens, leading to user irritation when changing display types.
Innovation Solution
A display control device with an acceptance unit, setting unit, and change unit that accepts change instructions for display types on multiple screens, sets a display type to ensure different types are displayed, and changes images accordingly, preventing identical types from being shown on both screens.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If display types are changed independently on each screen without coordination, then each screen can display different content types, but identical display types may be displayed on multiple screens causing user irritation
Solution Approach 1:
The system monitors the display types currently shown on all screens and uses this feedback information to control which display types can be selected for change. When a user attempts to change a display type on one screen, the system checks whether that same display type is already being used on other screens, and prevents the change if it would result in duplicate display types across screens.
2Ease of operation
If the system prevents identical display types on multiple screens, then user convenience is improved, but the complexity of display type management increases
Solution Approach 1:
The system pre-establishes a set of display types that are currently being used across all screens. Before allowing a display type change on any screen, the system checks this pre-established set to determine whether the requested display type is already in use elsewhere, and only permits the change if the display type is not currently assigned to any other screen.

AI summary
A display control device according to an embodiment includes an acceptance unit, a setting unit, and a change unit. The acceptance unit accepts a change instruction for a display type on each of a plurality of screens capable of displaying images with different display types. The setting unit limits and sets the display type in such a manner that images with an identical display type are not displayed on the plurality of screens when the display type is changed based on the change instruction. The change unit changes an image on a screen with the change instruction being applied thereto to an image with the set display type.
