Display Assembly Camera Module Positioning Light Blocking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices with a high screen-to-body ratio face limitations in display area due to the placement of camera modules outside the display panel, which reduces the screen-to-body ratio and can cause light interference from the display panel to the camera module.
Innovation Solution
The camera module is positioned within the display region of the display panel using a backlight module, with a light blocking layer on the mounting through hole to prevent light interference, allowing for a larger display area and improved screen-to-body ratio without complex positioning structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the camera module is placed outside the display panel, then the display area is reduced, but the camera module positioning is simplified
Solution Approach 1:
The camera module is merged with the display panel by positioning it within the display region, specifically in the non-display area. The backlight module serves dual purposes: providing backlight for the display and housing the camera module, thereby combining two functional elements into one integrated structure.
Solution Approach 2:
The backlight module is designed with multi-functionality, serving both as a light source for the display panel and as a housing structure for the camera module. This universal design eliminates the need for separate camera positioning structures, simplifying the overall device complexity while maintaining large display area.
2Area of stationary object
If the camera module is placed within the display region, then the screen-to-body ratio is improved, but light interference from the display panel to the camera module occurs
Solution Approach 1:
The backlight module is segmented into distinct functional regions: a light emitting area for display backlight and a camera housing area for the camera module. The light blocking layer further segments the optical path, creating clear separation between the light source and the camera sensor to prevent interference while maintaining the integrated structure.
Solution Approach 2:
A light blocking layer is introduced as an intermediary element between the display panel and the camera module. This layer selectively blocks light from reaching the camera module while allowing the camera to function normally, thereby resolving the light interference issue without requiring the camera to be positioned outside the display region.
3Object-affected harmful factors
If a light blocking layer is added to prevent light interference, then light interference is reduced, but the manufacturing complexity increases
Solution Approach 1:
The light blocking layer is merged with the mounting through hole structure, forming an integrated component. The mounting through hole serves multiple functions: positioning the camera module, providing light blocking walls, and facilitating assembly. This combination reduces the number of separate manufacturing steps and simplifies the overall manufacturing process.
Solution Approach 2:
The mounting through hole is designed with multi-functionality, serving as both a positioning feature for the camera module and a light blocking structure. By making the mounting structure itself perform the light blocking function, the patent eliminates the need for separate light blocking components, thereby maintaining ease of manufacture while preventing light interference.

AI summary
A display assembly (10) of an electronic device (20), the electronic device (20), and a method for manufacturing the display assembly (10) are provided. The electronic device (20) includes a display assembly (10) and a camera module (21). The display assembly (10) includes a cover plate (11), a display panel (12), and a backlight module (13) that are sequentially stacked together. The cover plate (11) has a light transmitting region, and the light transmitting region corresponds to a display region of the display panel (12). The display region of the display panel (12) defines a first mounting through hole (h1). The first mounting through hole (h1) is provided with a light blocking layer (15) on a hole wall of the first mounting through hole, and an end of the light blocking layer (15) close to the cover plate (11) is attached to the light transmitting region. The backlight module (13) defines a second mounting through hole (h2) aligned with the first mounting through hole (h1). The second mounting through hole (h2) is configured to position the camera module (21). With aid of the above, the electronic device (20) has a large screen-to-body ratio. In addition, the positioning structure of the camera module (21) can be simplified, and it is possible to prevent the light of the display panel (12) from interfering with the camera module (21).
