Multiple Image Display Device Bezel Compensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multiple image display devices with bezels create noncontinuous screens, leading to image distortion and reduced operability, especially when GUI elements are placed on edge portions that are not fully displayed.
Innovation Solution
A multiple image display device configuration that divides an input image into sections displayed on adjacent devices with an enlargement portion that adjusts image sizes based on device positions, ensuring edge portions are displayed and GUI elements are easily recognizable.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the input image is divided into portions and displayed on multiple image display devices with bezel portions, then the screen size is increased, but the screen becomes noncontinuous and image distortion occurs
Solution Approach 1:
The input image is divided into multiple portions corresponding to each image display device's display area. Each portion is independently processed and displayed on the respective device, enabling the system to achieve a larger combined screen area while maintaining proper image representation across all segments.
Solution Approach 2:
Different enlargement ratios are applied to different portions of the image based on the position of each image display device. Edge portions use different enlargement ratios compared to center portions, allowing the system to compensate for bezel interruptions and maintain image continuity across the entire multiple-device screen.
2Shape
If the image is enlarged to compensate for bezel portions, then image distortion is reduced, but edge portions of the input image are not displayed
Solution Approach 1:
The system applies different enlargement ratios to different spatial regions of the divided image. Center portions use one enlargement ratio while edge portions use another, ensuring that edge content remains visible and distinguishable from center content through appropriate size differentiation.
Solution Approach 2:
The enlargement ratio is dynamically adjusted based on the position of each image display device within the multiple-device configuration. Edge devices receive different enlargement treatment compared to center devices, allowing the system to adaptively preserve edge information while maintaining overall image continuity.
3Shape
If the screen is made continuous by enlarging division images, then image distortion is prevented, but GUI elements on edge portions become difficult to recognize
Solution Approach 1:
GUI elements in edge portions are displayed at different sizes compared to those in center portions, creating visual differentiation that helps users distinguish and locate interactive elements. This local variation in display quality maintains image continuity while improving operability through enhanced GUI visibility.

AI summary
In a multiple image display device that is provided with a plurality of image display devices and that displays a single input image, the image display devices each divide the input image into division images that are individually displayed on the image display devices, and enlarge and display them. In particular, the image display device provided in an edge portion of the multiple image display device enlarges the division image toward a side opposite from the side of the edge portion. In this way, the edge portion of the input image is displayed on the multiple image display.
