Solution Overview
Problem
Current display apparatuses lack an efficient method to integrate additional functions beyond image display, such as transmission of light or signals, while maintaining a compact and lightweight design.
Innovation Solution
A display apparatus design featuring a transmission area surrounded by a display area and a non-display area, with an insulating layer, display elements, and spacers, including organic and inorganic materials, to enable the integration of various functions like light transmission without compromising thickness or weight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a transmission area is integrated into the display apparatus to enable additional functions like light transmission, then the versatility and functionality of the display apparatus is improved, but the structural complexity increases
Solution Approach 1:
The display apparatus is divided into distinct functional areas: a display area for image display and a transmission area for light transmission and additional functions. This segmentation allows each area to be optimized independently, enabling the integration of transmission functionality without disrupting the display area's structure.
Solution Approach 2:
The transmission area is designed to serve multiple functions: light transmission, signal transmission, and housing additional components. By making this area multi-functional, the patent achieves versatility without requiring separate dedicated areas for each function, thereby managing structural complexity.
2Weight of moving object
If the display apparatus is made thinner and lighter to maintain compact design, then the portability and aesthetic appeal is improved, but the space available for integrating additional functions is reduced
Solution Approach 1:
The patent employs thin-film structures for the insulating layer and other components, allowing the display apparatus to maintain a thin and lightweight profile while still providing sufficient space within the layered structure to integrate additional transmission functionality.
Solution Approach 2:
Instead of adding transmission functions in the horizontal plane which would increase area, the patent utilizes the vertical dimension by creating a transmission area that extends through the thickness of the display apparatus, allowing light and signals to pass through multiple layers without significantly increasing the overall footprint.
3Reliability
If the insulating layer and spacer structures are added to enable transmission area functionality, then the reliability and performance of the transmission function is improved, but the manufacturing complexity increases
Solution Approach 1:
The insulating layer is designed to serve dual purposes: providing electrical insulation for the display elements and forming the base structure for the transmission area. The spacer is integrated to both maintain the gap between substrates and define the boundaries of the transmission area. By merging multiple functions into single structures, the patent improves reliability without proportionally increasing manufacturing complexity.

AI summary
A display apparatus includes: a first substrate including a transmission area, a display area that surrounds at least part of the transmission area, and a first non-display area between the transmission area and the display area; an insulating layer in the display area and the first non-display area; a plurality of display elements in the display area; a spacer above the insulating layer in the first non-display area and surrounding the transmission area; and a second substrate facing the first substrate.
