Optical Fiber Light Guide for Seamless Multi-Display Seams
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In large multi-display setups, the boundaries between display panels are often visually recognized as dark lines, which detract from the image quality and aesthetic appeal.
Innovation Solution
The use of a display device configuration that includes a light guide member with bundled optical fibers and an optical film to distribute and convert image light, minimizing the visibility of seams by ensuring uniform luminance and reducing light loss, thereby reducing the recognition of dark lines between panels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple display panels are arranged side by side to form a large multi-display, then the display area is increased, but dark lines become visible at the boundaries between panels
Solution Approach 1:
A light guide member is introduced as an intermediary component between adjacent display panels. This light guide member includes optical fibers that transmit light from one panel to another, serving as a mediator to eliminate the dark line effect at boundaries while preserving the increased display area achieved through panel arrangement
2Stability of the object's composition
If a light guide member with optical fibers is used to reduce dark line visibility, then the uniformity of light distribution is improved, but the device complexity increases
Solution Approach 1:
The light guide member utilizes optical fibers bundled together in a flexible configuration. These fibers can be arranged to match the boundary geometry between panels, providing uniform light distribution while maintaining a relatively simple and adaptable structure that can conform to different display configurations
3Object-affected harmful factors
If optical fibers are bundled to guide image light across panel boundaries, then the dark line effect is reduced, but light loss occurs in the transmission process
Solution Approach 1:
The solution replaces mechanical or structural approaches to boundary coverage with an optical system. By using optical fibers to guide light transmission across panel boundaries, the system achieves uniform light distribution and reduces dark line effects while maintaining high light transmission efficiency through the optical coupling mechanism

Implementation Method 1
a light guide member in which a plurality of optical fibers each including a core part and a cladding part are bundled and integrated, in which the core part guides the image light from an incident surface facing the display surface to an emission surface positioned opposite to the incident surface
Implementation Method 2
a first optical member provided on side opposite to the display section as viewed from the light guide member, in which the first optical member converts light distribution of the image light emitted from the emission surface
