Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multi-panel display devices experience image disconnection and rainbow phenomena due to bezel regions and chromatic dispersion, which affect image continuity and quality, especially in large screen applications like video walls.
Innovation Solution
The use of optical members with optical fibers, such as entire-surface and frame type optical members, are integrated into the display devices to refract and enlarge the light path, preventing image disconnection at bezel regions and incorporating protection films to prevent breakage and chromatic dispersion issues.

Engineering Contradiction Analysis
1Area of stationary object
If a multi-panel display device is used to realize a large screen, then the screen size is increased, but image disconnection occurs at the bezel region
Solution Approach 1:
An optical member comprising optical fibers is introduced as an intermediary between adjacent display devices. The optical member receives light from the display region of one device and transmits it to the bezel region of the adjacent device, thereby mediating the image continuity across the bezel gap and eliminating image disconnection.
Solution Approach 2:
The solution transitions from a two-dimensional display surface to a three-dimensional optical transmission path. By using optical fibers that extend from the display region through the bezel region to adjacent devices, the image information is transmitted in a third dimension (depth), allowing continuous image display across multiple panels without being constrained by the bezel gaps.
2Reliability
If optical members are used to improve image continuity, then image disconnection is reduced, but breakage due to collision of optical members occurs
Solution Approach 1:
A protection film is applied to the optical member before it is installed in the display device. This protection film serves as a cushioning layer that absorbs impact forces during assembly and operation, preventing direct collision between optical members of adjacent devices and thereby preventing breakage while maintaining image continuity functionality.
3Reliability
If optical members are used to improve image continuity, then bezel region issues are reduced, but rainbow phenomenon due to chromatic dispersion occurs
Solution Approach 1:
The refractive index parameter of the optical member is specifically optimized to minimize chromatic dispersion. By selecting materials and designing the optical fiber structure with appropriate refractive index characteristics, the separation of light into different wavelengths (rainbow phenomenon) is reduced while maintaining the light transmission function for image continuity.
Solution Approach 2:
Different regions of the optical member have different functional requirements. The core region is designed for efficient light transmission with specific refractive index properties to minimize dispersion, while the cladding region provides structural support and protection. This local differentiation of quality allows the optical member to simultaneously achieve image continuity and reduce rainbow phenomenon.
