Display Panel Abnormality Detection and Prioritized Image Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When a failure occurs in a display panel, the images and information intended to be displayed are not properly shown, leading to a disruption in the display of critical information such as navigation maps and vehicle control data.
Innovation Solution
A display device with a displayable region detecting unit, an abnormality-time display image generating unit, and an abnormality-time display control unit that identifies and displays a simplified or prioritized image in functional regions of the display panel, ensuring that essential information is still visible even during panel failures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the display panel operates normally without abnormality detection, then the full display functionality is available, but when an abnormality occurs, the image cannot be displayed properly
Solution Approach 1:
The system performs preliminary detection of displayable regions before abnormality occurs by continuously monitoring panel status. When abnormality is detected, the predetermined display scheme is already prepared and can be immediately activated, ensuring reliable display functionality without waiting for complex real-time analysis during failure
Solution Approach 2:
The system creates a copy or alternative representation of the display content that can be rendered in the displayable region. By generating a simplified or alternative image layout that fits within the functional portion of the panel, the system maintains display reliability without requiring complete system redesign
2Loss of information
If the system displays all intended images and information, then complete information is provided, but when abnormality occurs, not all images can be displayed
Solution Approach 1:
The system extracts and prioritizes critical information from the complete set of intended displays. By identifying and displaying only the most essential images and data in the available displayable region, the system minimizes information loss without requiring complex mechanisms to manage all possible display scenarios
Solution Approach 2:
The system displays a partial set of images that are most critical for safety and operation rather than attempting to display all intended information. This partial display approach accepts that not all information can be shown but ensures that essential information remains accessible, avoiding the complexity of managing complete information display under all failure modes
3Area of stationary object
If the display panel uses full display regions, then maximum display area is utilized, but when abnormality occurs in part of the panel, the affected region cannot display images
Solution Approach 1:
The system segments the display panel into functional displayable regions and non-functional abnormal regions. By identifying the boundaries and characteristics of each segment, the system can optimize image placement to utilize maximum displayable area while ensuring that critical information is positioned within reliable display regions
Solution Approach 2:
The system applies different display strategies to different regions of the panel. In displayable regions, full-quality display is maintained, while in abnormal regions, alternative approaches such as blacking out or redirecting content are applied. This local differentiation maintains overall display reliability while maximizing usable area
