Solution Overview
Problem
Current display panels face challenges in integrating various components within a limited display area while maintaining reliability and efficiency, particularly in arranging components like light-emitting diodes and electrodes to optimize display performance.
Innovation Solution
The display panel design includes a substrate with a display area, an opening area, and an intermediate area, featuring a light-emitting diode with a pixel electrode and opposite electrode, an inorganic insulating layer defining a trench, and a separator with a protrusion at the corner, which enhances component arrangement and reliability by separating functional layers and electrodes effectively.
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 of the display panel is improved, but the reliability deteriorates due to increased complexity and potential impurity penetration
Solution Approach 1:
The display panel is divided into distinct functional areas: a display area for light-emitting diodes, an opening area for component arrangement, and an intermediate area serving as a transition zone. The inorganic insulating layer with trench structure further segments the intermediate area to create isolated regions, preventing impurity penetration between different functional zones while maintaining overall reliability.
Solution Approach 2:
The inorganic insulating layer acts as an intermediary barrier between the display area and the opening area where components are arranged. The trench structure within this insulating layer creates additional isolation, serving as a mediator that prevents harmful factors from the component area from affecting the display area, thus maintaining reliability while allowing functional expansion.
2Adaptability or versatility
If the display area is expanded to include more components, then the functionality is improved, but the manufacturing precision deteriorates due to increased complexity
Solution Approach 1:
The display panel structure is segmented into distinct areas with clear boundaries: display area, opening area, and intermediate area. The inorganic insulating layer with trench structure further divides the intermediate area into isolated regions, creating well-defined manufacturing zones that simplify the fabrication process and maintain manufacturing precision despite the expanded functionality.
Solution Approach 2:
Different regions of the display panel are assigned different structural characteristics: the display area contains light-emitting diodes with specific layer structures, the opening area accommodates components, and the intermediate area features an inorganic insulating layer with trench structures. This local differentiation allows each region to be optimized for its specific function while maintaining overall manufacturing precision.
3Adaptability or versatility
If components are arranged in the display area, then the functionality is improved, but the display performance deteriorates due to potential impurity penetration and interference
Solution Approach 1:
The inorganic insulating layer with trench structure serves as an intermediary barrier that isolates the display area from the opening area where components are arranged. This mediator prevents impurity penetration from the component area to the display area, protecting the display performance and illumination intensity while allowing functional expansion.
Solution Approach 2:
The display panel is segmented into functionally isolated areas using the inorganic insulating layer with trench structures. This segmentation creates physical barriers that prevent impurity migration between regions, ensuring that component arrangement in the opening area does not compromise the display performance and illumination quality in the display area.

AI summary
A display panel includes a substrate including an opening area, a display area surrounding at least a portion of the opening area, and an intermediate area between the opening area and the display area, a light-emitting diode disposed on the display area and including a pixel electrode, an opposite electrode, and an intermediate layer between the pixel electrode and the opposite electrode, an inorganic insulating layer disposed on the intermediate area and defining a trench surrounding the opening area, and a separator disposed on an upper surface of the inorganic insulating layer and a side surface of the inorganic insulating layer, the side surface defining the trench, in the intermediate area, where the separator includes a protrusion at a corner portion of the inorganic insulating layer where the upper surface meets the side surface.
