Multi-panel Display Optical Fiber Plate for Seamless Image Continuity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multi-panel display devices experience image discontinuity at junction areas due to non-active bezel areas, which are not covered by images, especially when viewing angles exceed a certain degree, leading to exposure of bezels and a lack of seamless image display.
Innovation Solution
A plate-type optical member with optical fibers and resin support is integrated into the multi-panel display device, where optical fibers receive light from active areas and output it to non-active areas, including bezel regions, using fibers with input and output surfaces aligned to cover junction lines and provide magnification to ensure continuous image display across the panel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a multi-panel display device is used to create a large-scale display, then the display area is increased, but image discontinuity occurs at junction areas due to non-active bezel areas
Solution Approach 1:
An optical member comprising optical fibers is introduced as an intermediary element between the active display area and the non-active bezel area. The optical fibers transmit light from the active area through the optical member to the bezel area, effectively mediating the image transmission across the junction regions and eliminating the visual discontinuity caused by the bezel structures.
Solution Approach 2:
The optical member extends in the thickness direction (z-axis) relative to the display panel plane, creating a three-dimensional light transmission path. By positioning the optical member at a predetermined distance from the display panel and utilizing its thickness, the system achieves light transmission over the non-active bezel area without interfering with the two-dimensional display image quality.
2Adaptability or versatility
If the viewing angle increases beyond a certain degree, then more of the display area is visible, but the non-active bezel areas become exposed causing image discontinuity
Solution Approach 1:
The optical member is strategically positioned and configured to provide different optical functions in different regions. The light conduits are arranged to specifically target and illuminate the non-active bezel areas where image discontinuity occurs, while maintaining normal display functionality in the active areas. This localized optical enhancement ensures image continuity is improved precisely where needed without affecting other regions.
3Manufacturing precision
If an optical member is added to compensate for image discontinuity, then image continuity is improved, but the device complexity increases
Solution Approach 1:
The optical member serves multiple functions simultaneously: it transmits light from the active display area to the non-active bezel area, compensates for image discontinuity at junctions, and maintains a flat profile that integrates with the display device form factor. By consolidating these multiple functions into a single component, the solution improves image continuity without proportionally increasing overall device complexity.
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 effectively compensates for image discontinuity at junction areas, providing a seamless image display even at high viewing angles by transmitting light over non-active areas, including bezels, thus eliminating the visibility of bezels and ensuring a continuous image across the multi-panel display.
Implementation Method 1
The optical member includes a plurality of light conduits of a first refractive index and cladding portions surrounding the light conduits. The cladding portions have a second refractive index lower than the first refractive index.
Implementation Method 2
The light conduits include input surfaces receiving lights from active areas of the display devices and output surfaces transmitting the received light.

AI summary
In a plate-type optical member for a multi-panel display device in which a plurality of individual display devices are joined and which includes junction area in which non-active areas of the individual display devices are arranged, the plate-type optical member includes plural optical fibers that have input ends opened to the lower part of the plate-type optical member and output ends opened to the upper part of the plate-type optical member and a resin support that supports the optical fibers. It is possible to guarantee image continuity in panel junction areas by disposing the plate-type optical member on the front surface of the multi-panel display device.
