Display Panel Bonding Layout for Full-Screen Sensor Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current flexible display apparatuses with photosensitive elements, such as fingerprint recognition sensors or cameras, hinder the achievement of a full screen due to their installation requirements, which are not conducive to a seamless integration with the display panel.
Innovation Solution
The display panel design includes a bonding region with specific through holes and wiring configurations that accommodate photosensitive elements, ensuring uniform wiring load and impedance, allowing for a full screen display by avoiding wiring pressure and facilitating seamless integration of these elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If photosensitive elements are installed in the display apparatus, then the display apparatus can perform additional functions (fingerprint recognition, camera), but it hinders the achievement of a full screen display
Solution Approach 1:
The patent extracts the photosensitive elements from the display region and relocates them to the bonding region. This separation allows the display region to achieve full screen coverage while the bonding region accommodates the photosensitive elements through dedicated through holes, resolving the conflict between functional integration and display area.
2Adaptability or versatility
If photosensitive elements are installed in the display region, then additional functions are enabled, but wiring pressure increases and integration with the display panel becomes difficult
Solution Approach 1:
The photosensitive elements are extracted from the display region and placed in the bonding region, where they can be connected to the data lines through dedicated through holes. This extraction simplifies the wiring arrangement by separating the signal paths and reducing wiring pressure in the display region.
Solution Approach 2:
The bonding region acts as an intermediary zone between the display region and the external components. It provides a dedicated space with through holes that facilitate the connection of photosensitive elements to the data lines, simplifying the overall integration process.
3Area of stationary object
If through holes are created in the bonding region for photosensitive elements, then seamless integration is achieved, but the wiring structure becomes more complex
Solution Approach 1:
The through holes are created locally in the bonding region rather than throughout the entire display panel. This localized modification allows seamless integration of photosensitive elements without significantly complicating the overall wiring structure, as the changes are confined to a specific area.
Solution Approach 2:
The bonding region is segmented into areas with through holes for photosensitive elements and areas with normal wiring. This segmentation allows the wiring structure to accommodate additional elements without requiring a complete redesign of the entire wiring system.
