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

VSEngineering 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

Engineering Contradiction:
ImprovefunctionalityVSAvoidwater penetration resistance
Core Design Contradiction:
Adaptability or versatilityVSReliability

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.

Inventive Principle:
Principle #1Segmentation

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.

Inventive Principle:
Principle #2Taking out (Extraction)

2Strength

If organic film connection is maintained between transmission area and display area, then structural integrity is improved, but water penetration risk increases

Engineering Contradiction:
Improvestructural integrityVSAvoidwater penetration
Core Design Contradiction:
StrengthVSObject-affected harmful factors

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.

Inventive Principle:
Principle #2Taking out (Extraction)

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.

Inventive Principle:
Principle #3Local quality

3Strength

If multiple thin film layers are stacked in the intermediate area, then structural support is improved, but water penetration paths increase

Engineering Contradiction:
Improvestructural supportVSAvoidwater penetration paths
Core Design Contradiction:
StrengthVSObject-affected harmful factors

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.

Inventive Principle:
Principle #1Segmentation

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.

Inventive Principle:
Principle #2Taking out (Extraction)
