Color Diffusion Edge Eliminates Visible Lines in Modular Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current modular displays fail to create a single, continuous image when multiple displays are aligned due to visible edge lines, and existing LED technologies face inefficiencies in achieving white light output and varying phosphor ratios, leading to decreased image quality and chip waste.
Innovation Solution
A modular display system with a color diffusion edge instead of blocking dams around light emitting pixels, combined with a variable height buffer layer and additional control circuitry, allows for a single, continuous image without edge lines and improved light diffusion, using LEDs, OLEDs, or other light-based displays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If blocking dams are used around light emitting pixels to prevent color diffusion, then color accuracy between pixels is improved, but visible edge lines appear in the image reducing overall image quality
Solution Approach 1:
The patent applies color changes by transforming the blocking dam from a light-blocking structure into a light-emitting structure with specific color characteristics. The edge line structure is configured to emit light with intensity and color matching the adjacent pixel regions, thereby eliminating visible edge lines while maintaining color accuracy between pixels through controlled light emission rather than physical blocking
2Area of stationary object
If multiple display modules are aligned to create larger displays, then display size and functionality are improved, but visible edge lines and segmentation appear reducing image continuity
Solution Approach 1:
The patent applies merging by integrating the edge line structures of adjacent display modules into a unified visual field. The edge lines at module boundaries are configured to match the color and intensity characteristics of adjacent pixel regions, causing the human eye to perceive the multiple modules as a single continuous display without visible segmentation or boundary lines
Solution Approach 2:
The patent uses color changes to match the edge line emission characteristics across module boundaries. By controlling the wavelength, intensity, and temporal characteristics of light emitted from edge lines at module interfaces to match adjacent display regions, the patent eliminates visible boundaries and creates seamless large-area displays
3Measurement precision
If blocking dams are used to protect against color diffusion between pixels, then pixel color purity is improved, but resolution performance decreases due to visible edge lines
Solution Approach 1:
The patent applies intermediary by introducing edge line structures that emit light as a mediating element between adjacent pixels. These edge line structures act as intermediaries that fill the visual gap created by pixel boundaries, allowing pixels to maintain their blocking dams for color purity while the intermediary edge lines prevent resolution degradation by eliminating visible boundaries in the final displayed image

AI summary
Embodiments of the present invention provide light diffusion into edge lines of a modular display, and thus provide a modular display that is capable of displaying a single, continuous image without visible edge lines between individual display modules. One display module includes a multitude of pixels that contain red, green, blue, and white light sources. The replacement of an edge line blocking dam with the light diffusion edge line of the individual display module can provide a single, continuous image to be displayed thereon without visible, image-quality-reducing edge lines. With various heights of the buffer layer, the light can concentrate on the edge line in modular display. The individual display modules can be light emitting diode (LED), organic LED (OLED), UV LED, RGB LED, Phosphor-based LED, Quantum dot LED, or displays based upon a combination thereof. Furthermore, the variable height buffer layer allows for a modular display image in 2-dimensional or 3-dimensional formats.
