Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image quality improvement methods for vehicle display devices, such as OLEDs and LCDs, suffer from high costs and errors due to the need for high-capacity memory and complex display panels, and are particularly vulnerable to burn-in due to fixed graphic user interfaces.
Innovation Solution
A method and system that uses a user device and vehicle display controller to capture and analyze images for quality analysis, determining validity and calculating a compensation value to improve image quality without requiring continuous pixel data accumulation or complex panels, using personal electronic devices like smartphones.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If image data accumulation and storage method is used, then image quality improvement is achieved, but high-capacity memory is required causing high costs
Solution Approach 1:
The patent extracts only the necessary pixel data from the entire screen for compensation, rather than accumulating all pixel data. By focusing on specific regions or representative samples, the system achieves image quality improvement without requiring high-capacity memory storage for the complete display buffer.
Solution Approach 2:
The patent uses a user device (smartphone) to perform multiple functions: capturing the display screen, analyzing image quality, calculating compensation values, and transmitting correction data. This multi-functional approach eliminates the need for dedicated high-capacity memory hardware in the display system.
2Reliability
If image data accumulation and storage method is used, then image quality improvement is achieved, but prediction compensation based on estimation results in large errors
Solution Approach 1:
The patent implements a feedback mechanism where the user device captures the actual displayed image, analyzes the burn-in or image quality issues in real-time, and generates compensation values based on actual observed degradation. This closed-loop feedback system significantly improves compensation accuracy compared to open-loop prediction methods.
Solution Approach 2:
The system performs preliminary capture and analysis of the display image to identify burn-in patterns before applying compensation. By pre-analyzing the actual image quality state and calculating compensation values in advance, the system achieves more accurate correction rather than relying on estimation during display operation.
3Reliability
If active sensing method is used, then image quality improvement is achieved, but structurally complex display panel increases manufacturing cost
Solution Approach 1:
The patent introduces a user device as an intermediary between the display panel and the compensation system. Instead of embedding complex sensing hardware directly in the display panel, the external user device captures the displayed image and performs quality analysis, thereby avoiding structural complexity in the panel itself while still achieving image quality improvement.
Solution Approach 2:
The system creates a digital copy of the displayed image by capturing it with the user device camera. This optical copy is then analyzed for quality issues and used to generate compensation values, eliminating the need for physical sensors or complex structural modifications to the display panel.
4Ease of operation
If fixed graphic user interface is used, then vehicle display device operation is simplified, but vulnerability to burn-in and image quality deterioration increases
Solution Approach 1:
The patent applies periodic compensation actions to counteract the static nature of fixed GUIs. By continuously or periodically capturing the display, calculating compensation values, and applying corrections, the system addresses burn-in issues caused by fixed images without requiring changes to the GUI design or user interaction patterns.
