Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If light-emitting components are assembled in a fixed direction to ensure proper electrical connection, then electrical connectivity is improved, but assembly flexibility and manufacturing efficiency deteriorate
Solution Approach 1:
The patent applies asymmetry by designing the light-emitting component with an asymmetric structure where the first electrode and second electrode are positioned at opposite ends of the semiconductor layer. This asymmetric electrode arrangement allows the component to be assembled in multiple directions while maintaining proper electrical connection, as the asymmetric design creates a unique orientation that can be easily identified and connected during assembly, thereby improving both electrical connectivity and assembly flexibility
Solution Approach 2:
The patent employs inversion by creating a light-emitting component structure where the stacking order of layers can be inverted while maintaining functionality. The component is designed such that whether assembled in the original orientation or inverted, the electrical connection remains proper, allowing assembly in two directions without compromising electrical connectivity or manufacturing efficiency
2Illumination intensity
If multiple light-emitting elements are stacked to increase luminance, then luminance is improved, but device complexity and manufacturing difficulty increase
Solution Approach 1:
The patent merges multiple light-emitting elements into a single integrated component structure where first and second light-emitting elements are stacked and bonded together. This merging approach increases luminance by combining multiple light sources while simplifying the overall device structure through the bonding layer integration, reducing manufacturing complexity compared to separate assembled components
Solution Approach 2:
The patent utilizes vertical stacking in the third dimension to increase luminance by stacking multiple light-emitting elements one above another. This dimensional approach allows multiple light sources to be integrated in a compact vertical arrangement, increasing luminance output without significantly increasing the horizontal footprint or overall device complexity
3Reliability
If light-emitting components are designed with specific stacking order to ensure proper function, then device performance is improved, but assembly difficulty and potential breakage increase
Solution Approach 1:
The asymmetric electrode design creates a naturally identifiable orientation for the light-emitting component, allowing workers to assemble the component in the correct orientation without complex alignment procedures. The asymmetric structure maintains proper device performance while significantly easing assembly by providing visual and structural cues for correct placement
Solution Approach 2:
The component is designed to function properly in both original and inverted orientations, allowing assembly in two directions without compromising device performance. This inversion capability reduces assembly difficulty by eliminating the need for precise orientation control during manufacturing, thereby reducing assembly time and potential breakage

AI summary
Disclosed are a light-emitting component and a display device including the same. The light-emitting component includes a first light-emitting element, a second light-emitting element, and a bonding layer between the first and second light-emitting elements. The first and second light-emitting elements each have a first electrode, a first semiconductor layer, an active layer, a second semiconductor layer, and a second electrode are sequentially stacked, and in which the order in which the first electrode, the first semiconductor layer, the active layer, the second semiconductor layer, and the second electrode of the first light-emitting element are stacked and the order in which the first electrode, the first semiconductor layer, the active layer, the second semiconductor layer, and the second electrode of the second light-emitting element are stacked are opposite to each other. Therefore, the light-emitting elements may be autonomously assembled in two directions.
