Display Panel QR Code Mapping for Crack and Distortion Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information handling systems lack effective methods for detecting cracks and distortions in display panels, which are crucial for timely maintenance and authentication of visual inspections.
Innovation Solution
Incorporating a basic input/output system (BIOS) that generates and displays multiple QR codes across the entire display panel, allowing for the capture and validation of these codes using a mobile device to determine panel integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional visual inspection methods are used for display panel detection, then the detection process is simple to perform, but the detection precision and reliability are insufficient to accurately identify cracks and distortions
Solution Approach 1:
The patent uses QR codes as digital copies/representations of display panel regions. Each QR code encodes information about its location and serves as a machine-readable copy that can be validated to detect physical damage. This allows automated detection without complex imaging equipment.
Solution Approach 2:
The patent replaces manual visual inspection (mechanical/human process) with automated QR code scanning and validation (digital/electronic process). The mobile device camera and processing algorithms substitute for human eyes and judgment, significantly improving detection precision and reliability.
2Reliability
If multiple QR codes are displayed across the entire display panel to improve detection coverage, then the detection reliability improves, but the complexity of generating and managing the codes increases
Solution Approach 1:
The display panel is divided into multiple regions, each represented by a QR code. This segmentation allows comprehensive coverage of the entire panel while maintaining manageable individual code units. Each QR code independently represents a specific region, enabling localized damage detection.
Solution Approach 2:
The QR codes serve multiple functions: they encode location information, serve as validation targets for damage detection, and provide a standardized format that can be processed by any QR code scanner. This multi-functionality reduces the need for specialized detection equipment.
3Measurement precision
If comprehensive data collection from multiple QR codes is performed to improve detection accuracy, then the measurement precision improves, but the time required for data processing increases
Solution Approach 1:
The QR codes are pre-generated and displayed on the display panel before the actual inspection process. This preliminary action prepares the detection system in advance, so that during inspection, only simple scanning and validation operations are needed, minimizing processing time while maintaining high accuracy.

AI summary
An information handling system includes a display panel, and a basic input/output system (BIOS) in communication with the display panel. The BIOS builds multiple quick response (QR) codes. The BIOS provides the multiple QR codes to the display panel. When displayed the multiple QR codes fill an entire display area of the display panel. The BIOS stores the multiple QR codes in a storage of the BIOS.
