Dynamic Sub-Pixel Array for Stereo Display View Zone Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional stereo display apparatuses limit the viewer's ability to maintain a desired three-dimensional scene, leading to reversed images, ghost images, and distortions when the viewer moves outside a specific view zone, reducing the effectiveness of the stereo view experience.
Innovation Solution
A tracing-type stereo display apparatus that includes an image acquiring unit to determine the viewer's space position, an index member to generate an index table based on this position, and a sub-pixel array member to dynamically adjust the sub-pixel array, ensuring optimal stereo image presentation for both eyes by adjusting the view zone.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed sub-pixel array is used in conventional stereo display apparatuses, then the device structure is simple, but the viewer is limited to a special view zone and cannot maintain desired three-dimensional scene when moving
Solution Approach 1:
The patent applies the dynamics principle by making the sub-pixel array configurable rather than fixed. The control unit dynamically adjusts the sub-pixel array configuration based on real-time viewer position detection, allowing the display apparatus to adapt to different viewing positions and maintain optimal stereo view effects outside the traditional fixed view zone.
Solution Approach 2:
The patent implements feedback by using the tracing member to detect viewer position and feeding this information back to the control unit, which then adjusts the sub-pixel array accordingly. This closed-loop system enables continuous adaptation to viewer movement, resolving the contradiction between adaptability and complexity through intelligent control.
2Ease of operation
If the viewer moves outside the special view zone in conventional stereo display apparatuses, then the viewer gains freedom of movement, but reversed images, ghost images and distortions occur reducing stereo view effects
Solution Approach 1:
The patent makes the sub-pixel array dynamic and adaptable to viewer position. As the viewer moves freely, the tracing member detects the new position and the control unit reconfigures the sub-pixel array to maintain optimal stereo viewing conditions, preventing reversed images, ghost images, and distortions while preserving movement freedom.
Solution Approach 2:
The patent changes the configuration parameters of the sub-pixel array based on viewer position. By adjusting which sub-pixels are active and their corresponding pixel values, the system adapts to different viewing positions and maintains reliable stereo view quality throughout the extended view zone.
3Adaptability or versatility
If a fixed pixel arrangement algorithm is used, then the image processing is simple, but the stereo display apparatus cannot adapt to different viewer positions and space situations
Solution Approach 1:
The patent transforms the fixed pixel arrangement algorithm into a dynamic one. The control unit receives viewer position information from the tracing member and adjusts the pixel arrangement algorithm in real-time, selecting appropriate pixel values and configurations based on the current viewing conditions to maintain optimal stereo display quality.
Solution Approach 2:
The patent changes the parameters of the pixel arrangement algorithm based on viewer position. Different pixel values and arrangement patterns are selected according to the detected space situation, enabling the system to adapt to various viewing conditions while managing processing complexity through position-based parameter selection.
