Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current augmented reality display devices face challenges in providing a simple, high-efficiency see-through structure that allows simultaneous viewing of the real and virtual worlds without complex optics, leading to image degradation and reduced daytime visibility.
Innovation Solution
A display device comprising a display panel with spaced-apart organic light emitting diodes (OLEDs) and an optics array with pin hole structures, where each pin hole is surrounded by a shielding area, allowing for a one-to-one correspondence between display blocks and pin holes, and a spacer is used to optimize the spacing and resolution, enabling a lightweight, compact design with improved image transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a see-through structure is used to allow simultaneous viewing of real and virtual worlds, then visibility of the real world is improved, but image degradation occurs and daytime visibility is reduced
Solution Approach 1:
The display panel is divided into multiple display blocks that are spaced apart from each other, creating discrete light emission regions. This segmentation allows light to pass through the spaces between blocks, maintaining see-through capability while controlling image quality. The optics array is similarly segmented into multiple pin hole structures, each corresponding to a display block, enabling precise optical control for each region.
Solution Approach 2:
An optics array with pin hole structures is introduced as an intermediary component between the display panel and the user's eye. This intermediary selectively transmits light from corresponding display blocks while blocking stray light, thereby improving image quality and reducing degradation without compromising the see-through function. The pin holes act as optical mediators that filter and direct light paths.
2Reliability
If complex optics are used to improve image clarity, then image quality is improved, but device complexity increases
Solution Approach 1:
The patent employs simple pin hole structures instead of complex optical elements like lenses or mirrors. Pin holes are essentially simple apertures that can be easily manufactured and integrated into the optics array. This approach achieves effective optical control with minimal structural complexity, aligning with the principle of using simple, easily manufactured components rather than complex optical systems.
3Illumination intensity
If display blocks are spaced apart to enable see-through function, then real world visibility is improved, but resolution is reduced
Solution Approach 1:
The patent replaces traditional continuous display surfaces with discrete display blocks arranged in specific patterns. This mechanical reconfiguration allows light transmission through gaps while maintaining display functionality. The optics array with pin holes further refines the system by creating corresponding optical channels that maintain image resolution despite the spaced-apart block structure.
