Display Panel Camera Aperture Encapsulation Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing display technologies result in larger frame sizes for mobile terminals due to the placement of cameras in non-display areas, and attempts to integrate cameras within the display area have not effectively minimized the frame size.
Innovation Solution
A display panel design featuring a substrate with a thin film transistor layer, a light emitting layer, and an encapsulation layer, where the encapsulation layer has openings that expose the substrate, allowing for the integration of a camera within the display area while maintaining the display's functionality and preventing moisture ingress.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the camera is disposed in a non-display area of the screen, then the camera can be integrated into the display apparatus, but the frame size becomes larger
Solution Approach 1:
The patent moves the camera from the traditional non-display area (2D plane outside the display) into the display area itself, utilizing the display pixels to form the camera aperture. This dimensional repositioning allows the camera to occupy space within the display boundary rather than extending the frame outward.
Solution Approach 2:
The display pixels serve dual functions: they act as both display elements and camera aperture components. The same pixel array that displays images also creates the camera opening, eliminating the need for separate camera housing space and reducing overall frame size.
2Area of stationary object
If the camera is set in the display area to reduce frame size, then the frame size is reduced, but the display effect may be compromised and moisture resistance is challenged
Solution Approach 1:
The patent divides the display area into functionally distinct regions: a first area for normal display function and a second area for camera aperture function. This segmentation allows each region to be optimized independently - the first area maintains full display performance while the second area serves as the camera opening, with the encapsulation layer providing targeted protection where needed.
Solution Approach 2:
The encapsulation layer acts as an intermediary protective structure between the light emitting layer and the camera aperture opening. It prevents moisture ingress to the light emitting layer while allowing light to pass through to the camera sensor, thus protecting the display components without compromising the camera function or display effect.
3Adaptability or versatility
If openings are created in the encapsulation layer for camera access, then camera integration is enabled, but moisture resistance is compromised
Solution Approach 1:
The encapsulation layer is designed with spatially varying properties: it has openings in the second area to allow camera access while remaining intact and protective over the first display area and the light emitting layer. This local differentiation enables the encapsulation layer to simultaneously provide moisture protection where needed and optical access where required.
Solution Approach 2:
The patent creates a nested structure where the camera aperture is formed within the display area, and the encapsulation layer is positioned to cover the light emitting layer while having strategic openings. The encapsulation layer's opening is positioned to expose the substrate for camera access while the light emitting layer extends to cover the opening's edges, creating nested protective and functional zones.

AI summary
The present disclosure relates to a display panel comprising a display area. The display area may include a substrate having a third opening, a thin film transistor layer on a side of the substrate, a light emitting layer on a side of the thin film transistor layer opposite from the substrate, and an encapsulation layer on a side of the light emitting layer opposite from the substrate. The thin film transistor layer may have a first opening to expose the third opening and the encapsulation layer may have a second opening to expose the third opening. Orthographic projection of the second opening on the substrate may cover orthographic projection of the third opening on the substrate.
