Solution Overview
Problem
Existing vehicle monitoring and display systems face challenges in arranging image sensors and cameras separately from display apparatuses, affecting the interior space and visual perception of vehicles.
Innovation Solution
A vehicle monitoring and display system that integrates an image sensor with a transparent display apparatus, allowing the sensor to capture images synchronously with the display's frame synchronization signal, enabling the sensor to operate under the display panel without interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If image sensors are disposed separately from display apparatus, then display function is maintained, but interior space arrangement is affected and visual perception is reduced
Solution Approach 1:
The patent merges the image sensor and transparent display apparatus into a single integrated structure, where the image sensor is disposed behind the transparent display panel. This combination allows both components to occupy the same spatial footprint, improving interior space arrangement while maintaining separate functional operations through temporal multiplexing.
Solution Approach 2:
The system dynamically switches the transparency state of the display panel between transparent and opaque modes based on operational requirements. When image capture is needed, the panel becomes transparent to allow sensor access; when display is needed, it becomes opaque. This dynamic behavior resolves the contradiction by allowing both functions to share the same physical space at different times.
2Area of stationary object
If image sensor is disposed under transparent display panel, then space utilization is improved, but image capture is blocked by display images
Solution Approach 1:
The system employs periodic action by alternating between display mode and image capture mode in synchronized frames. The transparent display panel is set to transparent state during specific time intervals when image capture is required, and switches to opaque state during display intervals. This periodic switching ensures that the image sensor can capture unobstructed images while the display functions normally, resolving the information loss issue.
Solution Approach 2:
The system performs preliminary action by pre-synchronizing the transparency switching of the display panel with the image capture timing. Before image capture begins, the display panel is switched to transparent state and remains so throughout the capture duration, ensuring no display images block the sensor. This preliminary coordination prevents image capture quality degradation.
3Adaptability or versatility
If transparent display and image sensor operate independently, then device functionality is maintained, but spatial arrangement flexibility is reduced
Solution Approach 1:
The system implements feedback control through a synchronization signal mechanism where the display controller receives timing information from the image sensor controller and adjusts the transparency switching accordingly. This feedback loop ensures that the display panel's transparency state is always coordinated with the image sensor's operational state, enabling flexible spatial arrangement while maintaining functional independence through controlled synchronization.

AI summary
A vehicle monitoring and display system are provided. The vehicle monitoring and display system includes an image controller, a transparent display apparatus and an image sensor. The image controller provides a frame display signal and a frame synchronization signal. The transparent display apparatus is coupled to the image controller to perform display based on the frame display signal. The image sensor is covered by a part of the transparent display apparatus and is coupled to the image controller to capture images based on the frame synchronization signal when the part of the transparent display apparatus renders transparent.
