Asymmetrical Display Alignment for Visual Fusion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Head-mounted display devices for VR, AR, and MR often cause image blur, dizziness, and visual fatigue due to asymmetrical alignment of display components with the user's eyes, leading to discomfort and poor visual fusion.
Innovation Solution
A display method that adjusts the positions of overlapping regions on two displays to compensate for assembly tolerance by making the distances and directions of their center points asymmetrical, allowing for better fusion and improved comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the first display and the second display are aligned symmetrically with respect to the user's eyes, then the manufacturing process is simplified, but image blur, dizziness, and visual fatigue occur due to assembly tolerance
Solution Approach 1:
The patent applies asymmetry by deliberately designing asymmetrical alignment between the first and second displays relative to the user's eyes. Specifically, the distance from the first display's center to the first eye's center differs from the distance from the second display's center to the second eye's center. This asymmetrical configuration compensates for assembly tolerance and ensures accurate visual fusion, resolving the contradiction between simplified manufacturing and reliable visual quality.
2Device complexity
If the overlapping regions of the two displays are positioned symmetrically, then the device structure is simpler, but the user experiences visual fatigue and discomfort
Solution Approach 1:
The patent implements asymmetry in the overlapping region positioning by making the distance from the first display's center to its overlapping region center differ from the distance from the second display's center to its overlapping region center. This asymmetrical arrangement ensures that the overlapping regions align correctly with the user's eyes, eliminating visual fatigue and discomfort while maintaining manageable device complexity.
3Ease of manufacture
If symmetric alignment is used for the displays, then the assembly process is easier, but image blur and dizziness occur
Solution Approach 1:
The patent resolves image blur by implementing asymmetrical alignment where the distance from the first display's center to the first eye's center is intentionally made different from the distance from the second display's center to the second eye's center. This asymmetrical configuration compensates for assembly tolerance, ensuring that images from both displays fuse correctly and eliminating image blur, while still maintaining a relatively simple assembly process.

AI summary
A display method and an electronic device are disclosed. The electronic device displays a first image through a first display which is aligned with a first eye of a user and displays a second image through a second display which is aligned with a second eye of the user. An overlapping region is identified for each of the first image and the second image and includes at least one same object. A center point of the overlapping region of the first image is located at a first position and the center point of the overlapping region of the second image is located at a second position. A distance from the first position to a center point of the first image is not equal to a distance from the second position to a center point of the second image.
