Overlapping Display Devices for Seamless Large-Area Image Continuity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Large-area display devices composed of multiple connected display panels often exhibit image discontinuities and a noticeable grid pattern due to the non-display bezel areas, which detract from the image quality and aesthetics.
Innovation Solution
A large-area display device system where individual display devices are overlapped such that only one pixel in the overlapping area displays an image, while the others remain off, using a driving system that adjusts the position and bezel configuration to minimize the visibility of seams and maintain image continuity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple individual display devices are connected to form a large-area display device, then the display area is increased, but the non-display bezel areas create a noticeable grid pattern and image discontinuity
Solution Approach 1:
The patent introduces a new spatial dimension by overlapping display devices in the vertical direction rather than simply arranging them side-by-side in the horizontal plane. This stacking approach allows the bezel areas to be positioned in different depth planes, making them less visually prominent and reducing the grid pattern effect while maintaining the expanded display area.
Solution Approach 2:
The patent implements a nested structure where multiple display devices are stacked and overlapped, with each device partially contained within the visual field of others. The overlapping arrangement allows display areas to extend beyond individual device boundaries, creating a seamless large-area display while nesting the physical devices in a compact configuration.
2Area of stationary object
If the bezel area is minimized to reduce the grid pattern, then the non-display area is reduced, but the driving circuit space becomes insufficient
Solution Approach 1:
The patent relocates the driving circuits from the traditional planar bezel area into the vertical stacking dimension. By positioning driving circuits on different layers and utilizing the Z-axis space, the system accommodates all necessary driving components without requiring large horizontal bezel areas, thus resolving the conflict between minimal bezel and sufficient circuit space.
Solution Approach 2:
The overlapping bezel areas serve multiple functions: they provide the necessary space for driving circuits while simultaneously acting as part of the overall display structure. The stacked configuration allows bezel regions to fulfill both structural support and circuit housing roles, eliminating the need for separate dedicated circuit areas.
3Area of stationary object
If individual display devices are arranged side-by-side, then the display area is expanded, but the connection parts show noticeable seams and lattice patterns
Solution Approach 1:
The patent transitions from a two-dimensional side-by-side arrangement to a three-dimensional stacked configuration. By overlapping devices in the vertical dimension, the connection seams are moved out of the primary viewing plane, significantly reducing their visibility and eliminating the lattice pattern effect that plagues planar arrangements.
Solution Approach 2:
The patent merges the display areas of multiple individual devices by overlapping them, creating a unified visual field. The overlapping region combines the active display areas while the bezel areas are pushed to the periphery and different depth planes, effectively merging the individual displays into a seamless large-area display system.

AI summary
A large-area display device can include a first individual display device including a plurality of first pixels, and a second individual display device including a plurality of second pixels and overlapping with the first individual display device in an overlapping area. The first individual display device is configured to be driven so that one or more pixels among the plurality of first pixels that are overlapped by the second individual display device in the overlapping area do not display an image, and the second individual display device is configured to drive one or more pixels among the plurality of second pixels located in the overlapping area to display an image.
