Terminal Device Light Transmitting Element Camera
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing terminal devices face challenges in increasing the screen-to-body ratio while accommodating a front camera, as traditional methods either complicate the display panel structure or lead to dust accumulation and increased costs with mechanical structures.
Innovation Solution
Incorporating a light transmitting element connected to the camera lens and a light transmitting hole in the cover plate, allowing external light to reach the camera while positioning the camera below the display panel, which reduces the need for a light shielding area and enhances the screen-to-body ratio.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If the front camera is placed below the display panel to increase screen-to-body ratio, then the screen-to-body ratio is improved, but dust accumulation and structural complexity increase
Solution Approach 1:
The patent introduces a light transmitting element as an intermediary component that guides light from the external environment through the display panel to the camera lens positioned below it. This mediator enables the camera to capture light without requiring direct exposure to the external environment, thus preventing dust accumulation while maintaining functionality
Solution Approach 2:
The patent segments the light transmission path into distinct functional zones: a transparent middle area of the cover plate for light entry, a light transmitting element for light guidance, and the camera lens positioned in the opaque light shielding area. This segmentation allows each component to perform its specific function while protecting the camera from dust
2Reliability
If a light shielding area is added to accommodate the camera, then the camera can be protected, but the screen-to-body ratio decreases
Solution Approach 1:
The patent applies local quality by creating a transparent middle area in the cover plate where light transmission is needed, while maintaining an opaque light shielding area surrounding it for camera protection. The light transmitting element is selectively positioned only where needed to guide light to the camera, allowing protection without sacrificing overall screen-to-body ratio
3Ease of operation
If mechanical structures are used to accommodate the front camera, then the camera can be positioned, but device complexity and cost increase
Solution Approach 1:
The patent replaces mechanical positioning structures with an optical solution. Instead of using mechanical components to position and protect the camera, the invention uses a light transmitting element (optical fiber or waveguide) to guide light to the camera lens, eliminating the need for complex mechanical structures while achieving both positioning and protection
