Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices with display devices for augmented reality (AR) or virtual reality (VR) struggle to provide a high sense of immersion, high display quality, and low power consumption while maintaining a low manufacturing cost and achieving high pixel density.
Innovation Solution
The electronic device incorporates a first display device and a second display device, each with specific pixel configurations and colors, along with a half mirror and an eyepiece lens, to achieve high pixel density and effective image superimposition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If minute pixels are used to reduce pixel perception, then display quality and sense of immersion are improved, but device complexity and manufacturing difficulty increase
Solution Approach 1:
The display device is divided into multiple independent display units (first display device, second display device) with different pixel configurations. Each unit handles specific color channels or image components, allowing independent optimization of pixel density and structure for each unit while maintaining overall high resolution through their combination.
2Manufacturing precision
If multiple display devices are used to achieve high resolution, then display quality is improved, but power consumption increases
Solution Approach 1:
Different regions of the display system use different pixel configurations optimized for their specific functions. The first display device uses one pixel structure while the second display device uses another, allowing each region to operate efficiently for its intended purpose rather than using a uniform high-density configuration throughout.
3Manufacturing precision
If multiple display devices with different pixel configurations are used, then image resolution is improved, but manufacturing cost increases
Solution Approach 1:
The display system is segmented into multiple devices with different resolutions and pixel configurations. This allows each segment to be manufactured using optimized processes for its specific requirements, and the segments are then combined through optical components (half mirror, eyepiece lens) to achieve the final high-resolution image.

Function Achieved in This Case
This configuration enhances the sense of immersion and display quality, allows for higher resolution images closer to the gaze point, reduces power consumption, and lowers manufacturing costs while providing a novel electronic device structure.
Implementation Method 1
The first display device is provided at such a position that the first image is reflected by the first half mirror and enters the eyepiece lens
Implementation Method 2
The second display device is provided at such a position that the second image passes through the first half mirror and enters the eyepiece lens
Implementation Method 3
The first image is presented through the eyepiece lens. The second image is presented, through the eyepiece lens, to be superimposed on the first image
