Operation Display Device Dynamic Button Visibility Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In multi-function peripherals, such as image forming apparatuses, the limited size of operation panels makes it difficult to display all operation buttons simultaneously, leading to partial button identification information protruding from the screen during scroll displays, which can obscure functionality recognition for users.
Innovation Solution
An operation display device with a display control unit that changes the display mode of button identification information when it protrudes from the screen, using reduction, array change, arrangement position alteration, or omission indication to ensure full visibility, maintaining readability and usability during scrolling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If scroll display is used to display all operation buttons, then the quantity of displayed buttons is improved, but the visibility of button identification information deteriorates when buttons protrude from the screen
Solution Approach 1:
The display control unit dynamically changes the display mode of button identification information based on the button's position on the screen. When a button protrudes from the screen boundary, the system automatically switches from a first display mode (e.g., normal size) to a second display mode (e.g., reduced size or condensed format) to ensure the entire identification information remains visible within the display area.
Solution Approach 2:
The system changes display parameters (such as font size, text wrapping, or abbreviation level) of the button identification information based on the button's positional parameters. When detection shows that a button is partially outside the visible area, the display control unit adjusts the identification information's parameters to fit within the available space while maintaining readability.
2Loss of information
If the size of operation panel is increased to display all buttons simultaneously, then the visibility of all buttons is improved, but the device complexity and cost increase
Solution Approach 1:
Instead of using a fixed large display panel, the system employs dynamic adjustment of the identification information display mode based on button position. This allows a compact panel to effectively display all buttons by adaptively changing text size, format, or density when buttons are positioned at screen boundaries during scrolling.
Solution Approach 2:
The display control unit modifies parameters of the identification information (such as font size, line spacing, or text condensation) to maximize the use of available display space. This enables all buttons to be visible on a smaller panel by optimizing the information density dynamically.
3Measurement precision
If button identification information is displayed in full size, then the readability is improved, but the button may protrude from the screen boundary
Solution Approach 1:
The system dynamically adjusts the display mode of identification information based on real-time position detection. When a button is detected to be at the screen boundary, the system automatically transitions from a high-readability display mode to a condensed display mode that ensures the information stays within bounds while maintaining acceptable readability.
Solution Approach 2:
The display control unit changes parameters such as font size, text wrapping, or abbreviation level of the identification information to prevent protrusion. This parameter adjustment ensures that the information remains within the display area while preserving as much readability as possible through intelligent formatting.

AI summary
Disclosed is an operation display device, including: a display unit; a display control unit configured to display operation buttons; and an operation unit configured to receive an operation to one of the operation buttons, wherein in case that identification information is arranged in the operation button in a first display mode, when the operation button is displayed so as to display whole of the identification information in the display area, the display control unit displays the identification information in the first display mode, and in case that the identification information is arranged in the operation button in the first display mode, when a part of the identification information protrudes from the display area, the display control unit changes a display mode of the identification information to a display mode which is different from the first display mode, and displays the identification information in the operation button.
