Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing virtual reality devices face challenges in providing high-resolution images while maintaining a wide viewing angle without pixelation, which affects the three-dimensional effect and sense of immersion.
Innovation Solution
A display device with two display panels: one for the central region with high resolution and another for the peripheral region with lower resolution, synchronized to superimpose images, ensuring high resolution and preventing pixelation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a high-resolution display is implemented across the entire viewing area, then image resolution is improved, but device complexity and manufacturing difficulty increase
Solution Approach 1:
The display device is divided into multiple display panels, each responsible for different viewing angle regions. This segmentation allows each panel to be optimized independently, reducing overall system complexity while maintaining high resolution where needed.
Solution Approach 2:
Different display panels are assigned different resolution characteristics based on their intended viewing regions. The central viewing area receives high-resolution output from the first display panel, while peripheral regions use the second display panel, optimizing quality where it matters most without uniformly increasing complexity across the entire system.
2Manufacturing precision
If high-resolution images are provided for all viewing angles, then image quality is improved, but pixelation recognition occurs in peripheral regions
Solution Approach 1:
The patent applies different resolution characteristics to different spatial regions of the display output. The first display panel provides high-resolution images for central viewing angles where pixelation would be most noticeable, while the second display panel handles peripheral regions where the human eye is less sensitive to pixelation, thereby eliminating pixelation recognition in critical areas.
Solution Approach 2:
The system dynamically adjusts image output based on viewing angle. As the viewer's position changes, different display panels become active to maintain optimal image quality and prevent pixelation recognition across varying viewing conditions.
3Adaptability or versatility
If multiple display panels with different resolutions are used, then three-dimensional effect and immersion are improved, but device complexity increases
Solution Approach 1:
The viewing field is segmented into different angular regions, with dedicated display panels for each region. This segmentation enables the system to provide optimized three-dimensional effects and immersion for different viewing positions without requiring a single overly complex unified display structure.
Solution Approach 2:
Multiple display panels serve different functional roles within the same device - the first panel handles central high-resolution viewing while the second panel handles peripheral viewing. This multi-functionality allows the device to achieve superior three-dimensional effects and adaptability without each individual component becoming overly complex.

AI summary
A display device includes a first display panel realizing a first image light of a first resolution; and a second display panel realizing a second image light synchronized with the first image light, the second image light having a second resolution lower than the first resolution, wherein a second virtual image implemented by the second image light is superimposed with a first virtual image implemented by the first image light to implement a virtual reality image.
