Transparent Display Camera Layout for Image Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic devices face issues with alignment of camera and display areas, leading to misalignment of object images on the display, making it difficult to accurately sense and input user commands.
Innovation Solution
Incorporating a display panel with a light-emitting device unit and a transparent portion housing a camera, allowing for accurate sensing and display of objects without interference, and a controller to adjust and correct image positions for precise user input recognition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the camera is positioned separately from the display area, then the camera can independently sense objects, but the image of the object becomes misaligned with the display area position
Solution Approach 1:
The camera is integrated within the display panel structure, specifically positioned in a transparent portion of the display panel. This merging of the camera into the display assembly allows the camera to sense objects while the display simultaneously shows the captured image at the correct corresponding position, eliminating alignment issues between separate camera and display components
2Manufacturing precision
If the camera is integrated within the display panel, then image alignment is improved, but the display panel structure becomes more complex
Solution Approach 1:
The display panel is divided into different functional portions: a first portion with light emitting devices for display, and a second transparent portion housing the camera. This segmentation allows each portion to perform its specific function optimally while maintaining overall integration, reducing the complexity compared to a completely separate camera assembly
Solution Approach 2:
The display panel serves multiple functions: it displays images through the light emitting portion and simultaneously houses the camera for object sensing through the transparent portion. This multi-functionality eliminates the need for separate dedicated camera housing structures, simplifying the overall device architecture
3Ease of operation
If the camera senses objects over the display area, then user interaction is enabled, but the light emitting devices may interfere with object sensing
Solution Approach 1:
The display panel is segmented into a first portion with light emitting devices and a second transparent portion with the camera. This spatial segmentation separates the light emission function from the object sensing function, preventing light interference while maintaining user interaction capabilities through the transparent portion

AI summary
A cell phone includes a housing, a display panel disposed in the housing and including a first portion configured to display an image, the first portion including a plurality of light-emitting devices, and a second portion surrounded by the first portion and being transparent, and a camera unit disposed in the second portion of the display panel.
