Prismatic Optical Element for Seamless Multi-Screen Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multi-screen display setups are hindered by the frames surrounding the screens, which can affect viewing quality and create a disjointed visual experience due to the visibility of side edges when screens are assembled together.
Innovation Solution
A multi-screen display apparatus utilizing a prismatic structure optical element is placed between adjacent screens, covering their side edges and a portion of the display areas, allowing the screens to be arranged at angles greater than 90 degrees and less than 180 degrees, and an image processing module divides the display areas to ensure seamless image framing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple display screens are assembled together to form a multi-screen display apparatus, then the display area and information presentation capability are improved, but the frames surrounding each screen become visible and affect the viewing quality
Solution Approach 1:
A prismatic optical element is introduced as an intermediary component between adjacent display screens. This optical element refracts light to redirect the image from one screen toward the viewer's eye, effectively covering the visible frame and seam areas. The optical element acts as a mediator that optically connects the discrete screens while hiding the physical boundaries, thereby resolving the contradiction between expanded display area and reduced frame visibility.
Solution Approach 2:
The patent employs optical parameters (refraction angles, prism geometry) to change the path of light from the display screens. By adjusting the optical parameters of the prismatic element, the system transforms how light reaches the viewer's eye, allowing the display area to be effectively expanded while the frame visibility is reduced through optical redirection rather than physical removal.
2Area of stationary object
If the display screens are arranged at angles greater than 90 degrees and less than 180 degrees, then the preferred viewing area is expanded, but the complexity of the display apparatus increases
Solution Approach 1:
The patent transitions from a traditional planar arrangement of display screens to a three-dimensional configuration where screens are positioned at specific angles (greater than 90 degrees and less than 180 degrees). This spatial reconfiguration in another dimension allows the optical elements to effectively redirect light paths, expanding the preferred viewing area while managing the inherent complexity through geometric optimization.
3Object-affected harmful factors
If the prismatic optical element covers the side edges and part of the display areas, then the frame visibility is reduced, but the visible display area is decreased
Solution Approach 1:
The prismatic optical element creates an optical copy or virtual extension of the display content from one screen toward the viewer's eye. Instead of directly showing the physical display area, the optical element refracts light to create a virtual image that appears to extend the display content, thereby compensating for the area covered by the optical element itself and maintaining the perception of a larger visible display area.

Function Achieved in This Case
This configuration expands the preferred viewing area, eliminating the visibility of side edges and enabling a completely spliced image frame, thereby enhancing display quality and immersion.

AI summary
A multi-screen display apparatus includes a first display screen, a second display screen and a prismatic structure optical element. The display area of the first display screen includes a first main display area, a first and second sub display areas. The display area of the second display screen includes a second main display area, a third and fourth sub display areas. The fourth sub display area is adjacent to the second sub display area. The first main display area displays the first part of the first image frame. The first and fourth sub display areas display the second part of the first image frame adjacent to the first part. The second main display area displays the first part of the second image frame. The second and third sub display areas display the second part of the second image frame adjacent to the first part. A display method is also provided.
