Transparent-Edge Tiled Display Panels for Seamless Video Walls
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tiled display devices often have noticeable tiling gaps between adjacent display panels, which can detract from the overall display effect.
Innovation Solution
The solution involves designing a tiled display device where each display panel has a tiling edge that overlaps with the peripheral edge of a transparent part. This transparent part includes a substrate and a transparent filling layer, with the edge of the substrate and the transparent filling layer forming the tiling edge, thereby minimizing the visibility of the tiling gap.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If display panels are tiled together to provide a large display area, then the display area is increased, but noticeable tiling gaps appear between adjacent panels
Solution Approach 1:
A light absorbing layer is introduced as an intermediary element between adjacent display panels. This layer fills the tiling gaps and absorbs both ambient light and light emitted from LED elements, preventing the gaps from being visible. The light absorbing layer acts as a mediator that resolves the visual discontinuity caused by tiling while preserving the large display area.
Solution Approach 2:
The light absorbing layer is designed with optical properties that match or blend with the surrounding display elements. By controlling the optical characteristics (absorption of ambient light and emitted light) of this intermediate layer, the visual appearance of tiling gaps is eliminated, creating a seamless appearance across multiple panels.
2Shape
If the light absorbing layer is added to eliminate tiling gaps, then the visual appearance is improved, but the device structure becomes more complex
Solution Approach 1:
The light absorbing layer is merged with the existing display panel structure, integrating multiple functions into a single element. It simultaneously serves as a structural component, a light management element, and a visual seamless solution. This merging approach adds the necessary functionality without proportionally increasing overall device complexity.

AI summary
The disclosure provides a display panel (100A, 100B) and a tiled display device. The display panel has a tiling edge (102A, 102B) and includes a non-transparent part (104A, 104B) and a transparent part (106A, 106B). The transparent part has a peripheral edge (E106A, E106B). At least a portion (EA1, EB1) of the peripheral edge (E106A, E106B) of the transparent part (106A, 106B) is overlapped with the tiling edge (102A, 102B). The tiled display device includes a plurality of display panels tiled together by the tiling edges (102A, 102B) thereof.
