Camera Hole Display With Intermittent Organic Layer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The integration of a camera into display devices, such as organic light emitting display devices, often results in a protruding bezel and increased thickness, compromising the visual appeal and reliability due to separate manufacturing processes for the camera and display panel.
Innovation Solution
A display device structure with a camera hole in the active area, where subpixels are spaced apart from the camera hole, and organic common layers are intermittently removed to prevent moisture penetration, combined with an anti-crack pattern and barrier layer to enhance reliability and prevent structural damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the camera is accommodated in a bezel part at the peripheral portion of the display panel, then the camera can be integrated into the display device, but the bezel part protrudes and the peripheral portion has an increased portion to be hidden, resulting in increased thickness and degraded visual sense
Solution Approach 1:
The camera is relocated from the peripheral bezel area to the active display area, changing the spatial dimension of camera placement. This allows the camera to be integrated without increasing the peripheral thickness of the display device, as the camera module is positioned within the existing active area boundaries rather than extending the device envelope.
Solution Approach 2:
The camera module is nested within the active area of the display panel, utilizing the existing space allocated for display elements. By positioning the camera among or near the subpixels in the active area, the camera is accommodated without requiring additional peripheral space, thereby avoiding increased device thickness.
2Adaptability or versatility
If the camera is accommodated in a bezel part at the peripheral portion of the display panel, then the camera can be integrated into the display device, but the bezel part protrudes and the peripheral portion has an increased portion to be hidden, resulting in degraded visual appeal
Solution Approach 1:
The camera is relocated from the peripheral bezel area to the active display area, changing the spatial dimension of camera placement. This allows the camera to be integrated without creating protruding bezel portions that would disrupt the flat, uniform visual appearance of the display surface.
Solution Approach 2:
The camera is positioned within the active area where local structural variations are already present due to the pixel matrix. By placing the camera in this region with inherent subpixel structures, the camera integration does not create additional visual irregularities or protrusions that would degrade the overall visual appeal of the display.
3Ease of manufacture
If the organic common layer is continuously formed around the camera hole, then the manufacturing process is simplified, but moisture can penetrate through the continuous organic layer to the camera module, reducing reliability
Solution Approach 1:
The organic common layer is segmented into intermittent portions rather than being continuously formed around the camera hole. This segmentation creates discontinuities in the organic layer material that would otherwise provide a continuous moisture penetration path, thereby blocking moisture while maintaining manufacturing feasibility through patterned deposition processes.
Solution Approach 2:
The organic common layer material is selectively removed or not deposited in the region surrounding the camera hole, extracting the continuous layer structure in this specific area. This creates an interrupted organic layer configuration that prevents moisture penetration to the camera module while preserving the organic layer's moisture-blocking function in other regions.
4Area of stationary object
If subpixels are disposed close to the camera hole, then the active area utilization is maximized, but the structural integrity near the camera hole is compromised, increasing the risk of damage from foreign matter
Solution Approach 1:
The subpixels are positioned at a specific distance from the camera hole, creating a local quality difference in the spatial arrangement. This controlled spacing establishes a buffer zone that maintains structural integrity near the camera hole while maximizing active area utilization, as the subpixels are disposed as close as possible without compromising reliability.

AI summary
A display device can include a substrate having an active area and a peripheral area surrounding the active area; a camera hole disposed in the active area of the substrate; a plurality of subpixels disposed in the active area while being spaced apart from the camera hole by a first distance, the plurality of subpixels including a plurality of light emitting layers, respectively; and at least one organic common layer disposed on or under the plurality of light emitting layers, in which the at least one organic common layer includes an intermittent portion corresponding to a second distance from the camera hole, the second distance being less than or equal to the first distance.
