Display Assembly Border Concealment via Light Guiding Channels
Solution Overview
Problem
When multiple display devices are spliced together to form a large display, the border areas between them create a grid-like appearance, resulting in a non-continuous image presentation.
Innovation Solution
Incorporating image compensating components on each display device that include light guiding channels and prismatic structures to redirect light from the border areas, making them invisible and creating a seamless display by extending images from infill areas over the borders.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple display devices are spliced together to form a large display, then the display area is increased, but the border areas create a grid-like appearance resulting in non-continuous image presentation
Solution Approach 1:
The patent introduces an image compensating component as an intermediary element positioned at the border area between adjacent display devices. This component includes light guiding channels that optically connect the infill display area of one display device with the infill display area of the adjacent display device, thereby mediating the visual discontinuity caused by border areas and achieving seamless image presentation across spliced displays.
Solution Approach 2:
The patent addresses the two-dimensional border area problem by introducing a three-dimensional light guiding structure. The light guiding channels extend vertically from the front surface of the display device, creating a third dimension that allows optical paths to bypass the border area obstruction and connect infill regions across device boundaries, thus resolving the image continuity issue.
2Stability of the object's composition
If image compensating components are added to conceal border areas, then image continuity is improved, but device complexity increases
Solution Approach 1:
The image compensating component is constructed as a thin film structure with integrated light guiding channels, allowing it to be positioned flush with the front surface of the display device. This thin film approach minimizes the additional structural complexity while effectively concealing border areas and enabling seamless image presentation.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution ensures a continuous and uninterrupted display by concealing the border areas, providing a visually seamless image presentation by redirecting light from the border areas, thus enhancing the display effect.
Implementation Method 1
each of the first and second parts includes a plurality of light guiding channels
Implementation Method 2
prismatic structures to redirect light from the border areas

AI summary
A display assembly includes at least two display devices and two image compensating elements at a juxtaposition of every adjacent two display devices. Each display device includes a front surface that is viewed by user. Each front surface defines a display area and a border area. Each image compensating element is on the front surface. Each image compensating element includes a first part and a second part independent from each other, the first part is closer to the border area than the second part. Each of the first part and the second part includes a plurality of light guiding channels extending along a direction from a light-incident surface toward a light-emitting surface.
