Eye-Tracked Display Screen for High-Resolution See-Through Viewing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Transparent displays face challenges in achieving high brightness, high contrast, and high resolution due to their design and reliance on ambient light, which affects their display quality and perspective effect.
Innovation Solution
A display apparatus with a non-transparent display screen equipped with a first image capturing element to track the user's eye position and a second image capturing element to capture the scene behind the screen, using a control module to adjust and present the scene image in real time, ensuring accurate representation of the scene behind the screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If transparent displays are used to achieve perspective effect, then the perspective effect is improved, but the display resolution and quality deteriorate due to squeezed layout space
Solution Approach 1:
The patent uses image capturing elements (cameras) to capture the scene behind the display and presents this captured image on the display screen. This copying approach allows the display to show the blocked scene without requiring transparent pixels, thereby maintaining high display resolution while achieving the perspective effect.
Solution Approach 2:
The patent introduces image capturing elements as an intermediary to capture the scene behind the display and a control module to process and present the captured image. This intermediary system enables the perspective effect to be achieved through computational methods rather than physical transparent pixels, resolving the contradiction between transparency and resolution.
2Device complexity
If transparent displays utilize ambient light as illumination source, then the device complexity is reduced, but the display brightness and contrast deteriorate
Solution Approach 1:
The patent replaces the optical transparency mechanism with an electronic image capture and display system. Instead of relying on ambient light passing through transparent pixels, the system uses image capturing elements to capture the scene and electronically presents it on the display, enabling full utilization of the display's brightness and contrast capabilities.
3Manufacturing precision
If the display screen blocks the scene behind it, then the display quality is improved, but the perspective effect deteriorates as the scene cannot be seen through the screen
Solution Approach 1:
The patent uses image capturing elements to preliminarily capture the scene behind the display before it is needed for display. The captured image is then processed by the control module and presented on the display screen, allowing the perspective effect to be achieved without compromising display quality.
Solution Approach 2:
The system establishes a feedback loop where the image capturing elements continuously capture the scene behind the display, and the control module adjusts and presents the captured image on the display screen in real-time according to eye position tracking, maintaining the perspective effect while preserving display quality.
Data Source
AI summary
A display apparatus including a display screen, a first image capturing element, a second image capturing element, and a control module is disclosed. The display screen is provided with a display surface facing a user. The first image capturing element is disposed on a side of the display surface of the display screen, and is configured to trace an eye position of the user. The second image capturing element is disposed on a side of the display screen facing away from the display surface, and is configured to capture a scene image of a scene located in a line-of-sight of the user and blocked by the display screen. The control module is adapted to display at least a portion of the scene image on the display screen according to the eye position of the user.
