Screen Assembly Camera Integration via Optical Surface Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Full-screen electronic devices face challenges in achieving a light and thin design due to the complex stacking structure of front camera modules caused by perforated screens, which increases thickness and complicates the design.
Innovation Solution
The integration of a light-transmitting layer with an optical surface structure within the screen assembly, where a blind hole is formed to house the camera module, utilizing glass substrates as lens elements to reduce the number of stacked lens elements and simplify the design, while maintaining the original screen assembly structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a perforated screen is used to arrange the front camera, then the camera can be integrated into the full-screen device, but the stacking structure of the camera module becomes complicated and the thickness increases
Solution Approach 1:
The patent merges the screen assembly and camera module into a single integrated unit. The camera module is positioned directly on the screen assembly, sharing the same structural space. This integration eliminates the need for separate camera housing and reduces the overall stacking layers, thereby simplifying the structure while maintaining full-screen functionality
Solution Approach 2:
The screen assembly serves multiple functions: it acts as both the display component and the structural housing for the camera module. The rigid plate within the screen assembly provides both structural support and serves as the mounting base for the camera, eliminating the need for separate structural components
2Adaptability or versatility
If a perforated screen is used to arrange the front camera, then the camera can be integrated into the full-screen device, but the thickness of the module increases
Solution Approach 1:
The camera module is nested within the screen assembly structure. The rigid plate is embedded in the screen assembly, and the camera module is mounted on this rigid plate, creating a nested configuration. This nesting approach allows the camera components to occupy the same spatial envelope as the screen assembly, thereby reducing overall thickness
Solution Approach 2:
By merging the screen assembly and camera module into a single integrated unit with shared structural components, the patent eliminates redundant layers and reduces the overall thickness of the front camera assembly while maintaining full functionality
3Measurement precision
If multiple lens elements are stacked in the camera module, then the imaging performance can be improved, but the stacking thickness increases
Solution Approach 1:
The patent transitions from a vertical stacking arrangement of lens elements to a lateral distribution arrangement. Multiple lens elements are positioned side-by-side or in a planar configuration on the rigid plate rather than being stacked vertically, thereby maintaining the required number of optical elements for good imaging performance while significantly reducing the thickness dimension

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach significantly reduces the stacking thickness of the camera module, allows for a light and thin design, improves the utilization of screen space, and enhances the imaging effect with glass lenses offering higher refractive index and lower chromatic dispersion compared to plastic lenses.
