Display Device Fixed Base Area Screen Layout
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display technologies for operation panels in multifunctional digital image forming apparatuses face issues with visibility and usability due to varying screen sizes, as text and buttons become too large or small when enlarged or reduced, and require additional buttons and screens in extra blank areas, which is time-consuming to prepare.
Innovation Solution
A display device with a touch panel, memory storing screen configuration information, and a display processor that allocates fixed and unfixed areas for displaying primary and secondary screens, allowing users to expand extra areas dynamically based on user input, maintaining optimal screen visibility and usability across different screen sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the operation screen is enlarged or reduced to match the screen size of the display, then the display can accommodate various screen sizes, but the text and buttons become too large or small which degrades visibility and usability
Solution Approach 1:
The display screen is divided into a fixed-size base area and a variable extra area. The base area maintains a consistent coordinate system and displays critical operation screens with fixed positioning, ensuring text and buttons remain at optimal sizes. The extra area accommodates additional content and adapts to different screen sizes, resolving the contradiction between adaptability and visibility.
Solution Approach 2:
Different regions of the display are assigned different functions and scaling properties. The base area maintains fixed scaling for critical operations, while the extra area provides flexible scaling for additional content. This local differentiation allows the system to adapt to various screen sizes while preserving the visibility and usability of essential elements.
2Manufacturing precision
If the operation screen is displayed without being enlarged on a display having a large screen, then the original screen layout is maintained, but extra buttons and screens need to be created to fill the blank area which increases development time
Solution Approach 1:
The extra area is designed as a universal container that can display various types of content (buttons, screens, information) depending on the operational context. Rather than creating specific extra elements for each scenario, the system uses a single versatile area that adapts its content based on needs, significantly reducing development time while maintaining the original screen layout in the base area.
3Area of stationary object
If extra buttons and screens are created to be shown in the extra blank area, then the large screen can be fully utilized, but it requires significant time and resources to prepare and manage these additional elements
Solution Approach 1:
The extra area is implemented as a dynamic region that adjusts its content and size based on operational requirements. Rather than having a fixed set of extra buttons and screens, the system dynamically populates this area with relevant content, reducing the need to pre-create and manage numerous static elements while still utilizing the full display area effectively.

AI summary
A display device includes: a display; a touch panel disposed on the display; a memory that stores screen configuration information essentially including information of a base area of a fixed size and an extra area of an unfixed size; a retrieving portion that retrieves the screen configuration information therefrom; a display processor that allocates the base area in an image displayable area of the display on the basis of a reference point of the screen of the display and displays a first screen in the allocated base area, and that further allocates the extra area in an area other than the base area and displays a second screen in the allocated extra area when the image displayable area of the display is larger than the base area; and a judgment portion that judges whether or not a user stretches the extra area toward the base area on the touch panel.
