Under-Display Sensor Cover Assembly for Protected Position Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing optical sensor technologies face challenges in protecting the sensor at the bottom of a display while minimizing the increase in the size of the cover glass member, which can compromise design quality and rigidity.
Innovation Solution
The solution involves using a double-sided tape to secure the sensor module and replacing assembly screws, with a cover glass member extending downward to cover the optical sensor, and incorporating lenses and adhesive to refract light, maintaining sensor protection and rigidity while minimizing cover glass size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the cover glass member extends downward to cover the optical sensor, then the sensor is protected, but the size of the cover glass member increases
Solution Approach 1:
The patent divides the cover structure into two separate parts: the display cover glass member and a dedicated sensor cover glass member. This segmentation allows each cover to be optimized independently - the display cover maintains its original size while the sensor cover specifically protects the optical sensor, thus resolving the contradiction between sensor protection and minimizing overall cover glass size increase.
2Reliability
If the cover glass member extends downward to cover the optical sensor, then the sensor is protected, but the design quality is lowered
Solution Approach 1:
By separating the display cover glass from the sensor cover glass, the patent enables independent optimization of each component's shape and size. The sensor cover can be precisely sized to match the sensor area, avoiding unnecessary extension of the display cover and maintaining clean, minimalistic design aesthetics.
3Reliability
If the cover glass member extends downward to cover the optical sensor, then the sensor is protected, but the rigidity of the sensor module is reduced
Solution Approach 1:
The patent creates a separate sensor cover glass member that can be specifically optimized for rigidity and structural support of the optical sensor, while the main display cover glass maintains its original dimensions and structural integrity. This segmentation allows the sensor cover to provide necessary protection without compromising the overall rigidity of the sensor module assembly.

Function Achieved in This Case
This approach effectively protects the sensor at the bottom of the display while minimizing the cover glass size increase, ensuring rigidity and a unified appearance with the upper display screen, thereby enhancing the luxurious design.
Implementation Method 1
the sensor unit may include an adhesive conjoining the sensor unit and the cover glass member
Implementation Method 2
one or more lenses configured to refract (1) reference light emitted from one or more light-emitting elements and (2) the reference light reflected by the object and returning to the light-receiving element
