Beamsplitter Composite Display for Seamless High-Resolution Imaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional flat-panel displays are inadequate for rendering high-resolution imagery, especially in close-in, immersive viewing, and existing gesture recognition technologies using visible light cameras are computationally expensive and unreliable due to changing contrast from projected backgrounds.
Innovation Solution
A system combining multiple component displays using a beamsplitter to create a seamless high-resolution display, where one display area is viewed through the beamsplitter as a transmitted area and another as a reflected area, with the beamsplitter positioned to provide a composite image that is offset, allowing for a single large display with increased resolution and improved gesture recognition using infrared light.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If component displays are abutted in a tiled manner, then the display area is increased, but the bezel surrounding each component display prevents seamless display of a single high-resolution image
Solution Approach 1:
The patent positions component displays in different spatial planes (some in a first plane, others in a second plane offset forward) and uses a beamsplitter to combine their images optically. This dimensional arrangement allows the displays to be physically separated by bezels while still presenting a seamless composite image to the viewer through optical path manipulation.
2Difficulty of detecting and measuring
If visible light cameras are used for gesture recognition, then gesture detection is possible, but the changing contrast from projected backgrounds makes recognition computationally expensive and unreliable
Solution Approach 1:
The patent introduces infrared light as an intermediary for gesture detection. Instead of using visible light cameras that are affected by projected background contrast, the system uses infrared illumination and an infrared-sensitive camera. The infrared light serves as a mediator that illuminates the scene without being affected by the visible light projector, providing stable contrast for reliable gesture recognition.
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
The system achieves a seamless high-resolution display with increased pixel density and reliable gesture recognition by minimizing bezel interference and using infrared illumination to overcome contrast issues, enhancing the viewing experience and usability in scientific and intelligence applications.
Implementation Method 1
The first component display is positioned such that the first display area is viewable through the beamsplitter as a transmitted display area
Implementation Method 2
The second component display is positioned such that the second display area is viewable from the beamsplitter as a reflected display area

AI summary
An apparatus in one example comprises a first component display with a first display area, a second component display with a second display area, and a beamsplitter. The first component display is positioned such that the first display area is viewable through the beamsplitter as a transmitted display area. The second component display is positioned such that the second display area is viewable from the beamsplitter as a reflected display area. The first component display, the second component display, and the beamsplitter are positioned such that the beamsplitter provides a composite image of the transmitted display area and the reflected display area. The reflected display area of the composite image is at least partially offset from the transmitted display area.
