Under-Screen Camera Assembly for Full-Display Image Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The arrangement of a front camera on the front side of electronic devices, such as mobile phones, reduces the screen-to-body ratio due to occupying screen space, compromising display functionality.
Innovation Solution
The camera assembly is positioned under the screen with light transmitting portions smaller than the minimum visual resolution threshold, allowing multiple photographing sections to collect partial image data, which are processed to form an overall image, thus increasing the screen-to-body ratio without interfering with display effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the front camera is disposed on the front side of the apparatus body outside the display area, then the photographing function is ensured, but the screen-to-body ratio is reduced due to occupying screen space
Solution Approach 1:
The camera assembly is relocated from the front surface (2D plane) to the rear side of the display panel, utilizing the third dimension (depth) to resolve the space conflict. This allows the camera to function without occupying front screen space, thereby maintaining a high screen-to-body ratio while ensuring photographing capability.
Solution Approach 2:
The camera assembly is integrated within the display panel structure itself, with the lens positioned behind the display layer. The light transmitting portions are embedded in the display panel, creating a nested configuration where the camera system is housed within the existing device architecture without adding external protrusions.
2Area of stationary object
If light transmitting portions are made smaller than the minimum visual resolution threshold, then the screen-to-body ratio is increased and display quality is maintained, but the camera's ability to collect light may be compromised
Solution Approach 1:
The camera lens is divided into multiple photographing sections, each corresponding to a specific light transmitting portion. This segmentation allows the lens to collect light through multiple small apertures distributed across the display panel, maintaining sufficient light gathering capability while using smaller individual opening sizes that preserve display quality.
Solution Approach 2:
Multiple light transmitting portions, though individually small and invisible to the naked eye, are combined to work with multiple photographing sections of the lens. The light collected through these distributed small apertures is merged to form complete images, achieving both high screen-to-body ratio and adequate light collection capability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Ensures both photographing and display functions while enhancing the screen-to-body ratio by making the light transmitting portions invisible to the naked eye and optimizing camera assembly movement.
Implementation Method 1
the screen is provided with at least one light transmitting portion having a structural size smaller than a minimum visual resolution threshold of naked eyes
Implementation Method 2
the camera assembly is disposed under the screen, and includes a main control and at least one camera. The camera includes a plurality of photographing sections, and a photographing angle of view of each of the photographing sections is for correspondingly photographing a partial area of a scene to be photographed

AI summary
An electronic apparatus (1) comprises a screen (11) and a camera assembly (12). By disposing the camera assembly (12) under the screen (11) and setting the structural size of the light transmitting portion (111) smaller than the minimum resolution threshold of the naked eyes, the light transmitting portion (111) on the screen (11) is invisible to the naked eyes. A camera (121) of the camera assembly (12) includes a plurality of photographing sections (1211), and collects partial image data in the scene to be photographed by cooperation of each photographing section (1211) with a light transmitting hole. The main control (122) process all the partial image data, and finally produces an overall image of the scene to be photographed. Through above structural configuration, not only realization of a photographing function of the camera assembly (12) of the electronic apparatus (1) is ensured, but also the screen-to-body ratio of the screen (11) is increased, while avoiding interference of the camera assembly (12) with display effects of the screen (11).
