Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image display systems struggle to smoothly display 3D images when external signal sources fail to provide the necessary viewing angle switching signal.
Innovation Solution
The image display system, comprising an image decoding circuit, a 3D image processing circuit, and an image playback circuit, generates a processed viewing angle switching signal synchronized with the processed synchronization signal, enabling the display of 3D images even without an external viewing angle switching signal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the system relies on external signal sources to provide viewing angle switching signals, then the system can maintain simple structure, but the system fails when external signal sources cannot provide the required signals
Solution Approach 1:
The system generates the viewing angle switching signal internally through the viewing angle switching circuit based on the synchronization signal, making the system self-sufficient and eliminating dependency on external signal sources for this function
Solution Approach 2:
The viewing angle switching circuit acts as an intermediary that converts the synchronization signal into a viewing angle switching signal, enabling the system to derive the required signal from available resources
2Manufacturing precision
If the system processes synchronization signals through multiple circuits, then the system can generate accurate viewing angle switching signals, but time delays may occur between playback image signals and processed viewing angle switching signals
Solution Approach 1:
The viewing angle switching circuit generates the viewing angle switching signal in advance based on the synchronization signal, ensuring that the signal is ready at the appropriate time without causing delays in the overall signal processing pipeline
Solution Approach 2:
The delay correction circuit adjusts the phase or level of the processed viewing angle switching signal to compensate for processing delays, ensuring precise synchronization with the playback image signal
