Sliding Display Mechanism for Augmented Reality
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current augmented reality technologies, particularly in portable devices, face challenges in seamlessly integrating virtual images with real-world views, as captured images are not considered true augmented reality due to the lack of real-time superimposition capabilities.
Innovation Solution
A display device with a sliding mechanism that allows a secondary display area to protrude and stretch, incorporating transmissive areas to enable light from the rear to pass through, allowing users to see both the background and virtual images simultaneously, thereby providing augmented reality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If a camera is used to capture real-world images for augmented reality, then portability is improved, but the authenticity of augmented reality deteriorates because captured images are not real-time views
Solution Approach 1:
The display device is divided into multiple display areas: a first display area for virtual images and a second display area for real-world views. This segmentation allows the device to simultaneously provide AR content and authentic real-time views through different regions of the same display panel.
Solution Approach 2:
The patent introduces a third dimension (depth/protrusion) by making the second display area protrude beyond the lower member when in the extended position. This dimensional change enables the real-world view area to optically align with the user's eye while the virtual image area remains in the original plane, resolving the conflict between portability and AR authenticity.
2Reliability
If the second display area protrudes beyond the lower member to enable augmented reality viewing, then augmented reality capability is improved, but device compactness deteriorates
Solution Approach 1:
The second display area is designed to be movable between a retracted position (within the lower member) and an extended position (protruding beyond the lower member). This dynamic configuration allows the device to switch between compact storage mode and AR viewing mode, resolving the contradiction between compactness and AR capability.
Solution Approach 2:
When the second display area is not in use, it is nested within the lower member, making the device compact. When needed, it extends outward to provide the necessary optical path for augmented reality viewing. This nesting principle allows the device to maintain small form factor while providing full AR functionality when required.
3Reliability
If the number of pixels per unit area in the second display area is reduced to create transmissive areas, then augmented reality viewing is improved, but display resolution deteriorates
Solution Approach 1:
Different regions of the display panel have different pixel densities optimized for their specific functions: the first display area has high pixel density for virtual images, while the second display area has lower pixel density with transmissive areas optimized for real-world view transmission. This local quality differentiation resolves the contradiction between AR viewing quality and overall display resolution.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables the seamless superimposition of virtual and real images, enhancing the augmented reality experience by allowing users to view both background and virtual content simultaneously through the transmissive areas of the secondary display area.
Implementation Method 1
The second display area may further include transmissive areas disposed adjacent to the second pixels... light incident from the rear of a display device can be incident upon the eye of a user at the front of the display device, through the transmissive areas
Data Source
AI summary
A display device includes a display panel including a first display area having first pixels, and a second display area having second pixels. The display device includes a lower member below the display panel, a supporting member extended to the display panel, and a first slide module disposed between the lower member and the supporting member, the first slide module enabling the lower member and the supporting member to move relative to each other in a direction. The second display area protrudes beyond the lower member in the direction due to a movement by the first slide module. A number of first pixels per a unit area of the first display area is greater than a number of second pixels per the unit area of the second display area.
