Display Device Setting Screen Accessibility via Preliminary Action
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices do not effectively display user setting images to users who are not familiar with user settings, as the conditions for displaying these images are limited.
Innovation Solution
A display method and device that preset a display mode for showing a setting screen, accept an image signal from an external device, and display the setting screen when the image signal is inputted and the display mode is determined to be operational.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the display device determines the type of inputted image signal before displaying the user setting image, then the display device can avoid displaying the setting screen when the image signal type is known, but this limits the conditions for displaying the user setting image and may prevent users who are not familiar with user settings from accessing the setting screen
Solution Approach 1:
The display device displays the user setting image by default when an image signal is inputted, without first determining the signal type. This preliminary action ensures that the setting screen is always accessible to users, including those who are not familiar with user settings, while the device complexity is managed by using a straightforward display control mechanism rather than complex conditional judgment logic
2Ease of operation
If the display device displays the user setting image whenever an image signal is inputted regardless of signal type, then users can easily access the setting screen, but the display device cannot differentiate between known and unknown image signal types
Solution Approach 1:
The invention extracts the essential function of displaying the user setting image from the complex condition judgment process. By removing the prerequisite of image signal type determination, the system ensures that the setting screen is always displayed when an image signal is inputted, making it accessible to all users regardless of their familiarity with user settings, while maintaining reliable image signal type recognition through the interface circuit's normal signal processing functions

AI summary
A display method includes: presetting a display mode for displaying a setting screen; accepting an input of an image signal from an external device; and displaying the setting screen, when the image signal is inputted and it is determined that the display mode is in operation.
