Display Apparatus with Segmented Films for Water-Resistant Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display apparatuses face challenges in integrating various components within the display area while maintaining structural integrity and preventing water penetration, especially when incorporating components that require transmission of optical and acoustic signals.
Innovation Solution
A display apparatus design featuring a transmission area with a broken organic film connection and a second sub-intermediate area devoid of organic layers, utilizing an uneven pattern layer with inorganic films and protrusions to enhance structural integrity and prevent water penetration, while allowing for components to communicate optical and acoustic signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If various components are arranged in the display area to add functions, then the functionality and area utilization are improved, but water penetration risk and structural integrity deteriorate
Solution Approach 1:
The intermediate area is divided into first and second sub-intermediate areas with different film structures. The second sub-intermediate area has fewer thin film layers and no organic matter, creating a segmented approach to water protection while allowing component integration in the transmission area.
Solution Approach 2:
Organic matter and certain thin film layers are extracted (removed) from the second sub-intermediate area to eliminate water penetration paths. This extraction creates a cleaner, more water-resistant structure in the region adjacent to the transmission area while preserving functionality elsewhere.
2Strength
If organic film connection is maintained between transmission area and display area, then structural integrity is improved, but water penetration risk increases
Solution Approach 1:
Organic film connection is extracted (broken) between the transmission area and display area through the second sub-intermediate area. This removal of organic matter eliminates water penetration paths while the inorganic film structure maintains structural integrity.
Solution Approach 2:
Different regions have different film compositions: the first sub-intermediate area maintains full organic film connection for structural integrity, while the second sub-intermediate area removes organic matter to prevent water penetration. This local differentiation resolves the contradiction.
3Strength
If multiple thin film layers are stacked in the intermediate area, then structural support is improved, but water penetration paths increase
Solution Approach 1:
The intermediate area is segmented into regions with different numbers of thin film layers. The second sub-intermediate area has fewer layers than the first sub-intermediate area, reducing water penetration paths while maintaining necessary structural support through the inorganic film.
Solution Approach 2:
Certain thin film layers are extracted (removed) from the second sub-intermediate area to eliminate water penetration paths. This selective removal reduces the number of potential water channels while preserving essential structural functions.

AI summary
A display apparatus includes a display area and a transmission area on a substrate, and an intermediate area arranged between the display area and the transmission area and including a first sub-intermediate area and a second sub-intermediate area between the first sub-intermediate area and the transmission area, and a number of layers of thin films stacked on the substrate in the first sub-intermediate area is different from a number of layers of thin films stacked on the substrate in the second sub-intermediate area.
