Transparent Display Camera for Eye Contact and Space Saving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional communication terminals with cameras positioned in front of the device disrupt the video call experience by preventing users from maintaining eye contact with the conferencing party, and they often occupy unnecessary space in the device's housing.
Innovation Solution
A communication terminal with an image capturing sensor positioned behind the display, utilizing light-emitting devices that can switch between transparent and emitting states, allowing for effective image capture and processing, and synchronization with the display to ensure optimal image recording during video calls.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the camera is placed in front of the device, then the user can capture images during video calls, but the user cannot maintain eye contact with the conferencing party
Solution Approach 1:
The patent inverts the conventional camera placement by positioning the image capturing sensor behind the display rather than in front of the device. This allows the camera to capture images through the display during video calls, enabling users to maintain natural eye contact with the conferencing party while still capturing their image.
Solution Approach 2:
The display serves as an intermediary medium between the image capturing sensor and the external environment. The sensor captures images through the display, which then processes and transmits these images during video calls, resolving the conflict between image capture and eye contact maintenance.
2Measurement precision
If the camera is placed in front of the device, then the user can capture images, but it occupies unnecessary space in the device housing
Solution Approach 1:
The patent merges the display and camera functions into a single integrated structure. The image capturing sensor is positioned behind the display, utilizing the display's physical space for both visual output and image capture, thereby eliminating the need for separate camera housing space.
Solution Approach 2:
The display serves multiple functions: it displays video content to users and simultaneously acts as a medium through which the image sensor captures images of the user during video calls. This multi-functionality reduces the overall device volume by eliminating redundant components.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enhances the video communication experience by allowing users to maintain eye contact and saves space in the device, while ensuring high-quality image capture and transmission during video calls.
Implementation Method 1
the display comprises a number of light emitting devices, at least one of which has a first state in which the light emitting device is transparent allowing light to pass through the light emitting device and be captured by the image capturing sensor and a second state in which the light emitting device emits light
