Color-Coded Disabled Input Element Indication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices fail to clearly indicate the cause of a disabled input element on a display panel, leading to user confusion and inefficient input operations, especially in limited display areas and when deactivation is due to reasons other than exclusive settings.
Innovation Solution
A display device that determines the cause of a disabled input element and displays the corresponding area in a specific color, allowing users to identify the reason for deactivation without requiring additional display space, by using a determiner and display controller to perform color-based identification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If grayout function or uniform color is used to deactivate input element, then deactivation is achieved, but user cannot identify the cause of deactivation
Solution Approach 1:
The patent applies different colors to represent different causes of deactivation. When an input element is deactivated, the system displays a background color corresponding to the specific cause (e.g., red for required field empty, yellow for format error). This color-coded system allows users to quickly identify the cause of deactivation without additional text explanations, directly resolving the information loss problem while maintaining reliable deactivation indication.
Solution Approach 2:
The system changes the visual parameter (color) of the input element or its container based on the deactivation cause. By mapping different cause types to different color parameters, the system transforms invisible cause information into visible visual cues, enabling users to understand why an input element is deactivated without requiring extra display space or text.
2Loss of information
If area around input item is displayed in different color to indicate cause, then cause identification is improved, but display area is wasted
Solution Approach 1:
The patent applies color coding locally to the input element itself or its immediate container, rather than displaying the cause explanation in a separate area. By making the input element or its direct background color-coded, the system provides cause identification information within the minimal necessary space, avoiding waste of display area while maintaining excellent cause identification.
Solution Approach 2:
The system merges the deactivation indication and cause identification into a single visual element - the color of the input element or its container. Instead of separating the deactivated state display from the cause explanation, the patent combines both functions into one color-coded visual cue, eliminating the need for additional display area while providing complete information.
3Adaptability or versatility
If exclusive setting indication is displayed, then exclusive relationship is clear, but cannot be applied to other deactivation causes
Solution Approach 1:
The patent creates a universal color-coding system that can handle multiple types of deactivation causes through a single mechanism. Different colors represent different cause categories (required field empty, format error, business rule violation, etc.), allowing the same visual indication method to serve multiple functions across various deactivation scenarios, greatly enhancing adaptability while maintaining cause specificity.
Solution Approach 2:
The system uses color as a variable parameter that changes according to the deactivation cause. By mapping different cause types to different color values, the system maintains a consistent indication mechanism (color change) while adapting to various deactivation reasons, achieving both universality and cause specificity through parameter variation.

AI summary
To provide a display device including a display that displays an input screen having one or a plurality of areas arranged with an input element, a determiner that determines a cause of a disabled state if the input element is in the disabled state, and a display controller that performs control to identifiably display the one or the plurality of areas arranged with the input element in the disabled state, in a color corresponding to the cause.
