Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wearable electronic devices, such as smart watches and head-mounted displays, have limited display sizes, restricting the amount of information that can be displayed due to their compact nature.
Innovation Solution
A display device comprising a display component and a light path converting component that outputs initial light to form a virtual image perceived at a larger size than the display component, with the light path converting component including a visible area located separately from the display component on a plane, allowing for image amplification and flexible placement within the device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the display size is increased to show more information, then the information display capacity is improved, but the device size and weight increase
Solution Approach 1:
The patent uses a light path converting component to create a virtual image that is a visual copy of the original display content. The display component generates an initial light corresponding to the first image, and the light path converting component forms a virtual image perceived at a larger size. This allows the device to display high-resolution content on a small physical display while the user perceives a larger image, effectively copying the visual information without increasing the physical display size or device weight.
Solution Approach 2:
The patent transitions from a two-dimensional physical display to a three-dimensional virtual image space. The light path converting component performs light path conversion to form a virtual image perceived at a particular position in space, allowing the display content to extend into the third dimension. This enables the user to perceive a larger image without increasing the physical footprint of the display component, effectively utilizing spatial dimensionality to resolve the contradiction between information display capacity and device size.
2Loss of information
If the display area is increased to display more information, then the information display capacity is improved, but the device structure becomes more complex
Solution Approach 1:
Instead of physically enlarging the display area, the patent creates a virtual copy of the display content through light path conversion. The display component maintains its small physical size while the light path converting component generates a virtual image that appears larger to the user. This copying approach allows high information display capacity without requiring a larger physical display area or more complex device structure.
Solution Approach 2:
The light path converting component acts as an intermediary between the small display component and the user's perception. It receives the initial light from the display component and performs light path conversion to form a virtual image perceived at a larger size. This intermediary approach enables the system to achieve large information display capacity without directly increasing the display area or complicating the overall device structure, as the intermediary handles the size transformation.
3Measurement precision
If a virtual image is formed at a larger perceived size, then the image display quality is improved, but the light path conversion complexity increases
Solution Approach 1:
The light path converting component creates a virtual image that is a precise optical copy of the original display content. It receives the initial light corresponding to the first image and forms a virtual image perceived at a particular position with a size greater than the display component. This copying process maintains the image quality and resolution while achieving larger perceived size, as the virtual image faithfully reproduces the original content without requiring complex processing or multiple optical elements.
