Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional 3D display devices face issues with non-uniformity in the fabrication and lamination of lenticular lenses, leading to increased costs and crosstalk between pixels, which affect the quality of the 3D image.
Innovation Solution
A stereoscopic display device with an optical modulator and a controller that adjusts pixel data based on calculated pixel offsets between the pixel centers and the closest reference line of the lenses, eliminating crosstalk and improving 3D image quality by compensating for pixel offsets, eyes position offsets, lens offsets, and display curve offsets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If lenticular lenses are used to direct images of different views to different directions, then 3D visual effect is achieved, but fabrication non-uniformity and lamination issues cause increased cost and pixel crosstalk
Solution Approach 1:
The patent changes the parameter of pixel data by applying offset values to compensate for lens position deviations. Instead of requiring precise manufacturing of lens positions, the system adjusts the digital parameters (pixel data) to account for manufacturing variations, thereby maintaining 3D image quality without increasing manufacturing precision requirements.
Solution Approach 2:
The patent creates a digital copy or map of the actual lens positions (pixel offset map) and uses this information to adjust pixel data. Rather than physically correcting lens positions, the system creates a digital representation of the manufacturing variations and compensates through data adjustment, reducing the need for expensive precision manufacturing.
2Device complexity
If conventional 3D display algorithm is used, then device complexity is reduced, but pixel crosstalk and non-uniformity problems persist, affecting 3D image quality
Solution Approach 1:
The patent performs preliminary action by calculating and storing the pixel offset map before actual 3D image display. The system pre-characterizes the lens array positions and creates compensation data in advance, so that during operation, only simple data lookup and adjustment is needed. This preliminary characterization enables simple real-time operation while achieving high 3D image quality.
