Crack Sensing Lines for Display Openings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices with integrated cameras face space constraints due to camera placement outside the image display area, leading to reduced display space and challenges in detecting cracks around openings.
Innovation Solution
Incorporating crack sensing lines around openings in the display device, which disconnect when a crack occurs, allowing for the detection of cracks through changes in pixel column luminance, enabling accurate identification of crack locations and distinguishing them from other cracks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a camera is integrated into the display device, then the camera function is achieved, but the display area is reduced
Solution Approach 1:
The patent places the camera within the opening area of the display panel, nesting the camera structure inside the display device housing. The camera is positioned in the opening without requiring additional external space, thus achieving camera integration while minimizing impact on display area.
2Measurement precision
If crack sensing lines are added around openings, then crack detection accuracy is improved, but device complexity increases
Solution Approach 1:
The patent divides the crack sensing function into multiple separate sensing lines, with each sensing line assigned to detect cracks around specific openings. This segmentation allows for precise localization of cracks to particular openings while maintaining independent sensing pathways, improving detection accuracy without creating a monolithic complex system.
Solution Approach 2:
The sensing lines serve multiple functions: they detect cracks around openings, identify the specific location of cracks, and differentiate between cracks around openings versus cracks in other areas. This multi-functionality reduces the need for separate specialized sensors for each detection task.
3Adaptability or versatility
If multiple openings are present in the display panel, then camera integration is enabled, but crack detection becomes more difficult
Solution Approach 1:
The patent assigns dedicated sensing lines to each opening, creating distinct detection zones. When a crack is detected, the system can identify which specific opening's sensing line triggered the detection, thereby locating the crack to a specific opening among multiple openings in the display panel.
Solution Approach 2:
The sensing lines act as intermediaries between the cracks and the detection system. Each sensing line mediates the detection for its associated opening, translating physical crack presence into detectable signal changes that can be correlated with specific opening locations.
