Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a planar area for additional functions is added within the display area, then the versatility of the display apparatus is improved, but the display quality and reliability may deteriorate
Solution Approach 1:
The display area is segmented into a first area for display elements and a second area for additional functions. This spatial segmentation allows both display functionality and additional functions to coexist without interfering with each other, maintaining display reliability while enabling function integration.
Solution Approach 2:
Different regions of the display apparatus are assigned different functional qualities. The first area is optimized for display quality with high-density pixel electrodes, while the second area is optimized for additional functions with appropriate component placement. This local differentiation ensures each region performs its intended function effectively.
2Area of stationary object
If the display area is expanded to include additional functions, then the planar area for functions is improved, but the display quality may deteriorate
Solution Approach 1:
The display area is divided into distinct first and second areas with different functional requirements. This segmentation allows independent optimization of each region, ensuring that the first area maintains high display quality while the second area accommodates additional functions, thereby preventing display quality deterioration.
Solution Approach 2:
Each area is designed with local quality tailored to its function. The first area uses high-density pixel electrodes for superior display quality, while the second area is configured for additional functions. This localized optimization prevents the expansion for functions from compromising display quality.
3Adaptability or versatility
If a component using light or sound is integrated into the display area, then the versatility is improved, but the display area integrity may deteriorate
Solution Approach 1:
The display area is segmented into a first area for display elements and a second area for components using light or sound. This segmentation isolates the additional components from the display region, preventing them from interfering with display area integrity while still allowing them to function within the overall display apparatus.
Solution Approach 2:
An encapsulation layer is introduced as an intermediary between the display elements and the additional components. This encapsulation layer protects the display elements from potential interference by the light or sound components, thereby maintaining display area integrity while enabling function integration.

AI summary
A display apparatus includes a display element; a substrate including: an opening area, a display area adjacent to the opening area, a non-display area between the opening area and the display area, and a boundary line separating the opening area from the non-display area; an encapsulation layer including: a first inorganic encapsulation layer, an organic encapsulation layer and a second inorganic encapsulation layer in the display area, and the first inorganic encapsulation layer and the second inorganic encapsulation layer extending from the display area to the non-display area; and a dam portion in the non-display area and corresponding to the boundary line. The dam portion which corresponds to the boundary line includes a plurality of grooves in which the first inorganic encapsulation layer and the second inorganic encapsulation layer which are in the non-display area, are in contact with each other.
