Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing screen frames with opaque structures for terminals compromise structural stability and manufacturing complexity due to the need for openings to accommodate optical sensors, leading to stress concentration and increased equipment costs.
Innovation Solution
A screen frame with a light-transmitting member that allows light to penetrate while maintaining structural integrity, reducing the number of openings and simplifying the manufacturing process, and incorporating a light-transmitting member that absorbs or reflects light to provide shielding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If openings are provided on the opaque screen frame to accommodate optical sensors, then the optical sensor functionality is maintained, but the structural stability deteriorates due to stress concentration
Solution Approach 1:
The screen frame material transitions from opaque to light-transmitting, changing the optical parameter of the material. This allows the frame to maintain structural integrity without openings while still enabling optical sensor functionality through the light-transmitting property of the material itself
Solution Approach 2:
The openings are completely removed from the screen frame structure. Instead of having discrete openings for optical sensors, the entire frame becomes light-transmitting, extracting the need for openings while maintaining the required functionality
2Reliability
If openings are provided on the screen frame for optical sensors, then the sensor use is guaranteed, but the device complexity increases due to additional manufacturing requirements
Solution Approach 1:
Changing the material parameter from opaque to light-transmitting simplifies the manufacturing process. Instead of requiring precise opening creation, assembly of multiple components, and potential reinforcement structures, the frame can be manufactured as a single light-transmitting piece, reducing device complexity
Solution Approach 2:
The light-transmitting frame material serves multiple functions simultaneously: it provides structural support, enables optical transmission for sensors, and maintains aesthetic appearance. This multi-functionality reduces the need for separate components and simplifies the overall device structure

AI summary
The present disclosure provides a screen frame (2), a display screen module (3) and a terminal (4), and belongs to the technical field of the terminal. The screen frame (2) is provided with a light-transmitting member (22), and the light-transmitting member (22) absorbs or reflects light, so that a light flux passing through the light-transmitting member (22) is less than a light flux of incident light in the same direction. The screen frame (2) keeps the structural integrity of the screen frame (2) on the premise of realizing the original functions of the screen frame (2) in the related art, thereby optimizing the stability and simplifying the processing technology.
