AR Eyewear Display Layout Using One Screen for Both Eyes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wearable electronic devices that provide augmented reality by blocking a real space and providing virtual images to the user's eyes are heavy due to the inclusion of optical systems and electronic components for both eyes, leading to discomfort during prolonged use.
Innovation Solution
A wearable electronic device is designed with a single display that separates images for the left and right eyes using transparent members and projection lenses, allowing each eye to receive a distinct image from different regions of the display, reducing the overall weight and complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If optical systems and electronic components are arranged in a pair for both eyes, then augmented reality function is achieved, but device weight increases
Solution Approach 1:
The patent merges the optical systems for both eyes into a single shared optical path. A single display device generates images that are optically divided and directed to both eyes through beam splitters and optical waveguides, eliminating the need for separate displays and optical systems for each eye, thereby reducing overall device weight while maintaining augmented reality functionality
Solution Approach 2:
The single display device serves multiple functions by generating images for both eyes simultaneously. The optical system is designed to distribute the same or different images from one display to multiple viewing paths, making the display and optical components universal for serving both eyes rather than requiring dedicated components for each

Solution Approach 2:
The patent introduces optical waveguides and beam splitters as intermediary components that enable a single display to serve both eyes. These intermediaries facilitate the division and distribution of light paths, allowing one display to effectively become two viewing systems without requiring two separate display devices, thus reducing complexity

AI summary
A wearable electronic device is provided. The wearable electronic device includes a display, a first transparent member including a first surface facing a user's right eye and a second surface facing away from the first surface, a second transparent member including a third surface disposed to face the user's left eye, and a fourth surface facing away from the third surface, and a processor configured to output a first image by using a first region of the display or output a second image by using a second region different from the first region, wherein the first transparent member receives the first image and provides the first image to the user's right eye, and the second transparent member receives the second image and provides the second image to the user's left eye.
