Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current head-mounted visual display apparatuses face challenges in producing high-resolution images within a limited budget, requiring complex optical amplification systems and resulting in granular images due to pixel dot visibility, which lowers image quality.
Innovation Solution
A display device with a display unit divided into multiple areas, each containing pixel units of the same color, utilizing a first optical module to converge and overlap image light from these areas to form a display image, simplifying the fabrication process and reducing production costs while improving image quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a complex optical amplification system is used to achieve high resolution, then image quality is improved, but device complexity and production cost increase
Solution Approach 1:
The display unit is divided into multiple display areas, each containing pixel units of the same color. This segmentation allows each area to be processed independently with simpler optics, while the overall high resolution is achieved through the combination of multiple areas. The first optical module converges and overlaps image light from these segmented areas to form the final high-resolution display image.
2Manufacturing precision
If pixel unit dimensions are precisely controlled to reduce pixel dot visibility, then image quality is improved, but manufacturing precision requirements increase
Solution Approach 1:
By segmenting the display into multiple areas with uniform pixel colors, the patent reduces the need for extremely precise pixel unit dimensions. Each display area can be manufactured with relaxed tolerance, and the segmentation itself helps mask the visibility of individual pixel dots when the areas are optically overlapped.
Solution Approach 2:
Each display area is designed with uniform local quality (same color pixel units within each area), which simplifies the manufacturing process. The local uniformity within areas compensates for the lack of precise dimensional control at the individual pixel level, making fabrication easier while maintaining overall image quality.
3Ease of manufacture
If a simple fabrication process is used to reduce production cost, then ease of manufacture is improved, but image resolution deteriorates
Solution Approach 1:
The patent achieves high resolution through segmentation of the display into multiple areas that are optically combined, rather than through complex high-precision manufacturing of a single large display. This allows simpler fabrication processes for each area while achieving high overall resolution through the optical module that converges and overlaps the image light from all areas.
