Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current optical testing methods for display panels face challenges in accurately determining the position of a detector due to non-uniform optical characteristics across the panel, often relying on rough estimates or patterns, which can lead to errors in measurement.
Innovation Solution
A detecting device comprising a controller, a detector, and at least one image acquirer with an adjustable shooting angle, which acquires images of adjacent sides of a rectangular plane to determine the detector's position based on the shooting angle and acquired images, using edge information and shooting ratios to calculate precise positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the detector position is determined roughly using unaided eyes or tessellated patterns, then the operation is simple and quick, but the measurement precision deteriorates due to non-uniform optical characteristics across the display panel
Solution Approach 1:
The patent introduces an image acquirer as an intermediary device that captures images of the display panel and its surrounding environment. This intermediary system mediates between the detector and the positioning system, providing visual information that enables accurate detector positioning without requiring complex direct measurement mechanisms. The image acquirer serves as a bridge that translates physical spatial relationships into processable image data.
Solution Approach 2:
The patent replaces rough manual positioning methods with an automated image-based positioning system. Instead of relying on human eyes or simple mechanical patterns, the system uses image acquisition and processing to automatically determine detector position. This substitution of mechanical/manual methods with optical-digital methods significantly improves measurement precision while maintaining operational simplicity.
2Measurement precision
If multiple image acquirers are used to capture images of adjacent sides, then the measurement precision improves through comprehensive edge detection, but the device complexity increases
Solution Approach 1:
The patent divides the image acquisition task into segments by using multiple image acquirers positioned to capture different sides of the display panel. Each image acquirer is responsible for capturing images of specific adjacent sides, allowing comprehensive edge detection through distributed sensing. This segmentation approach improves measurement precision by ensuring all relevant edges are captured while distributing system complexity across multiple simple, identical components.
Solution Approach 2:
The patent merges the positioning information from multiple image acquirers to determine the final detector position. By combining images from different sides and integrating the edge detection results, the system achieves comprehensive position determination. This merging process consolidates information from multiple sources to overcome the limitations of individual image acquirers.
3Adaptability or versatility
If the image acquirer has an adjustable shooting angle, then the adaptability improves for capturing different panel configurations, but the device complexity increases
Solution Approach 1:
The patent implements a dynamic shooting angle capability in the image acquirer, allowing the capture angle to be adjusted based on the specific display panel configuration being tested. This dynamic adjustment enables the system to adapt to different panel sizes, orientations, and test requirements. The adjustable angle mechanism provides versatility while maintaining relatively simple implementation through basic mechanical or motorized adjustment.
