Subpixel Design for Under Display Camera Clarity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display panels with under display cameras (UDCs) face challenges due to the interference of pixel structures with incident light, leading to visual artifacts such as color fringing and trails of light in captured images.
Innovation Solution
The implementation of sub-pixel designs with static and dynamic corners, where the position of dynamic corners is adjusted to disrupt the periodicity of angles, thereby reducing the scattering of light and minimizing visual artifacts in images captured by UDCs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If pixel structures are positioned between the display panel surface and the under display camera, then the display panel can function normally, but visual artifacts such as color fringing and trails of light appear in captured images
Solution Approach 1:
The patent applies asymmetry by positioning the under display camera at an offset location relative to the pixel array, rather than at the center. This asymmetric positioning changes the angle at which light passes through the pixel structures, thereby altering the scattering pattern and reducing the formation of visual artifacts such as color fringing and light trails in captured images.
2Ease of manufacture
If regular polygon configuration of sub-pixels is used, then manufacturing is simplified, but high energy lines appear in the point spread function causing visual artifacts
Solution Approach 1:
The patent introduces asymmetry by offsetting the under display camera position relative to the regular pixel array, which effectively disrupts the periodicity of light scattering patterns. This asymmetric configuration reduces the formation of high energy lines in the point spread function, thereby minimizing visual artifacts while maintaining the simplicity of regular polygon sub-pixel geometry for manufacturing.
