Display Panel Isolation Slot Layout for Under-Screen Camera Openings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display panels with a front photographing function face issues of abnormal patterns around the opening area due to the camera device, affecting display effect, and existing isolation slots lead to air entrapment and process disruptions.
Innovation Solution
The display panel incorporates a staggered isolation slot design with a first and second slot body, disconnecting the light-emitting functional layer, and using different materials for the separation and planarization layers to facilitate air discharge while blocking water vapor and oxygen intrusion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a hole is opened in the screen for the camera device, then the camera can take images without being blocked by the screen, but abnormal patterns appear around the opening area affecting display effect
Solution Approach 1:
The isolation slot is divided into two separate slot bodies (first slot body and second slot body) that are sequentially arranged towards the substrate. This segmentation allows the slot to effectively isolate the opening area and prevent abnormal patterns while maintaining the camera's photographing function through the opening.
2Productivity
If an isolation slot is provided to prevent air entrapment, then the manufacturing process can be completed smoothly, but the slot structure becomes complex requiring multiple slot bodies
Solution Approach 1:
The isolation slot is segmented into two slot bodies arranged in sequence, where each slot body serves a specific function in air discharge. The first slot body allows air to escape during manufacturing, and the second slot body provides additional isolation. This segmented approach prevents air entrapment that would disrupt the manufacturing process while maintaining structural feasibility.
Solution Approach 2:
The two slot bodies are sequentially arranged in the depth dimension towards the substrate, creating a three-dimensional isolation structure. This dimensional arrangement allows effective air discharge pathways without requiring excessive lateral complexity, resolving the contradiction between isolation effectiveness and structural simplicity.
3Reliability
If the light-emitting functional layer is disconnected in the isolation slot, then water vapor and oxygen intrusion is blocked protecting the display panel, but the layer continuity is interrupted
Solution Approach 1:
The light-emitting functional layer is intentionally disconnected or extracted from the isolation slot region. By removing the layer continuity in the slot area, the patent creates effective isolation that blocks water vapor and oxygen intrusion pathways, accepting the localized discontinuity as necessary for protective function.
Solution Approach 2:
The light-emitting functional layer maintains continuity in the pixel area while being disconnected only in the isolation slot region. This local quality change ensures that the protective isolation function is achieved where needed (in the slot) without compromising the overall functionality of the light-emitting layer in the display area.

AI summary
A display panel of the present disclosure includes a substrate. A driving layer is arranged on a side of the substrate, and has an opening, a pixel area outside the opening, and a transition area therebetween; a surface of the driving layer distal to the substrate is provided with an isolation slot, located in the transition area and surrounding the opening. The isolation slot includes a first and second slot body intercommunicated towards the substrate. An orthographic projection of one side wall of the second slot body is outside that of the first slot body, and an orthographic projection of another side wall of the second slot body is between that of the two side walls of the first slot body. The light-emitting device layer is arranged on the surface of the driving layer distal to the substrate and includes a light-emitting functional layer, disconnected in the second slot body.
