Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multi-display apparatuses face challenges in seamlessly connecting images between coupled display panels, resulting in disconnections when unit panels are aligned in a line or mosaic shape.
Innovation Solution
The solution involves overlapping display panels with transparent substrates and adhesive members, along with transmitting windows and reflective members, to ensure continuous image display without disconnections, using a multi-panel configuration with strategically placed drivers and encapsulation layers to maintain pixel luminance and prevent light leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If unit display panels are coupled in a line or mosaic shape to realize a large screen, then the screen size is increased, but the image connection between panels becomes discontinuous
Solution Approach 1:
The patent transitions from a planar arrangement of display panels to a three-dimensional overlapping configuration. The second display panel is positioned to overlap the first display panel, creating a layered structure where the non-display region of the first panel overlaps with the display region of the second panel. This spatial reconfiguration enables continuous image display across panel boundaries by utilizing the overlapping volume to bridge the gap between adjacent panels.
Solution Approach 2:
The patent introduces transmitting windows as intermediary elements located in the non-display region of the first display panel. These windows serve as mediators that allow light from the second display panel to pass through to the viewer, effectively bridging the visual gap between panels. The transmitting windows act as optical intermediaries that enable the overlapping regions to function as continuous display areas.
2Reliability
If transmitting windows are disposed in the first non-display region over second pixels, then image continuity is achieved, but device complexity increases
Solution Approach 1:
The non-display region of the first display panel serves multiple functions: it maintains the structural integrity of the first panel, houses driving circuits, and simultaneously acts as a transmitting window region that allows light from the second panel to pass through. By making the non-display region multi-functional, the patent eliminates the need for separate transmitting window structures, thereby reducing overall device complexity while maintaining image continuity.
Solution Approach 2:
The patent merges the non-display region of the first panel with the display region of the second panel into a unified overlapping structure. This consolidation integrates multiple functions (structural support, circuit housing, and light transmission) into a single spatial configuration, reducing the number of discrete components and simplifying the overall device architecture.

Implementation Method 1
first transmitting windows may be disposed in the first non-display region over at least some of the plurality of second pixels
Implementation Method 2
a first reflective member that is opaque and does not overlap the plurality of first pixels

AI summary
A multi-display apparatus may include a first display panel and a second display panel at least partially overlapping the first display panel. The first display panel may include a first display region in which a plurality of first pixels are disposed, and a first non-display region adjacent to the first display region. The second display panel may include a second display region in which a plurality of second pixels are disposed. The first non-display region may overlap the second display region, and first transmitting windows may be disposed in the first non-display region over the second pixels.
