Under-Screen Camera Light Through Hole Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electronic devices with front camera modules face challenges in achieving a full screen design while ensuring the camera function is not compromised, as traditional camera modules occupy significant screen space and are prone to damage from frequent extension and retraction.
Innovation Solution
The implementation of an under-screen camera module with a light through hole in the display screen, allowing the camera module to receive sufficient light while being integrated beneath the screen, thus reducing the overall height and preserving the full-screen design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a front camera module is provided on the same side of the display screen, then the camera function is ensured, but the screen-to-body ratio is reduced due to occupied screen space
Solution Approach 1:
The camera module is relocated from the traditional front-side position to an under-screen position, utilizing the space dimension below the display. This dimensional transition allows the camera to function without occupying screen real estate, thereby maintaining a high screen-to-body ratio while ensuring camera functionality through the light-through hole in the display.
2Area of stationary object
If a telescopic camera module is used to hide the camera, then the screen-to-body ratio is improved, but the camera module is prone to damage from frequent extension and retraction
Solution Approach 1:
The camera module is pre-positioned in a fixed under-screen location rather than requiring repeated extension and retraction movements. This eliminates the mechanical wear and damage risks associated with telescopic mechanisms while maintaining the aesthetic full-screen appearance, as the camera operates from a stationary position beneath the display.
3Area of stationary object
If the camera module is placed under the display screen, then the screen-to-body ratio is improved, but sufficient light collection may be compromised
Solution Approach 1:
The display screen is segmented with a light-through hole at the position corresponding to the under-screen camera module. This segmentation allows light to pass through the display structure to reach the camera sensor, ensuring sufficient light collection for imaging while maintaining the overall full-screen design and high screen-to-body ratio.

Function Achieved in This Case
This solution enables the camera module to collect sufficient light, improves the screen-to-body ratio, and reduces the risk of damage associated with traditional camera module mechanisms, while maintaining a sleek, full-screen appearance.
Implementation Method 1
a light through hole penetrates through at least a part of the display screen in a height direction, so that light outside the display screen is received by the camera module below the display screen via the light through hole
