Display Assembly Image Compensating Elements Seamless Splicing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When multiple display devices are spliced together to form a large display screen, the border areas between them create a grid-like appearance, resulting in non-continuous images.
Innovation Solution
Incorporating image compensating elements and light guiding sheets on the display devices, which are positioned at the intersections of adjacent displays to mask the border areas, ensuring uniform brightness and creating a seamless visual experience by redirecting light from the infill display areas to cover the border regions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple display devices are spliced together to achieve a large display screen, then the display area is increased, but the border areas create a grid-like appearance resulting in non-continuous images
Solution Approach 1:
The patent introduces image compensating elements as intermediary components positioned at the borders between adjacent display devices. These elements receive light from the display areas and redirect it to illuminate the border areas, acting as a mediator that transfers visual information from the display regions to the previously dark border regions, thereby eliminating the grid appearance and achieving visual continuity across spliced displays
Solution Approach 2:
The patent applies local quality by making different parts of the display system have different functions: the display areas emit light directly to show images, while the border areas use image compensating elements to redirect and distribute light from adjacent display areas. This localized functional differentiation allows the border regions to contribute to the overall image display, eliminating the visual discontinuity caused by dark borders
2Ease of operation
If image compensating elements are added to mask border areas, then visual continuity is improved, but the device complexity increases
Solution Approach 1:
The image compensating elements serve multiple functions simultaneously: they redirect light from display areas to illuminate border areas, they act as optical guides to maintain image continuity, and they function as structural components that can be integrated into the display device assembly. This multi-functionality reduces the need for separate components for each function, thereby limiting the increase in overall device complexity
Solution Approach 2:
The patent replaces complex mechanical or electronic systems that would traditionally be needed to create seamless displays with a simpler optical solution. Instead of using mechanical adjustments, electronic blending techniques, or complex projection systems, the invention uses passive optical elements (image compensating elements with light-guiding structures) to achieve visual continuity, thereby reducing device complexity

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 conceals the border areas, presenting a continuous and seamless image to the viewer by compensating for uneven brightness and masking the grid-like appearance, thereby enhancing the visual cohesion of the combined display.
Implementation Method 1
Incorporating image compensating elements and light guiding sheets on the display devices, which are positioned at the intersections of adjacent displays to mask the border areas, ensuring uniform brightness and creating a seamless visual experience by redirecting light from the infill display areas to cover the border regions

AI summary
A display assembly includes at least two display devices and two image compensating elements at a junction 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 light-incident surface on the display area, a light-emitting surface coupling to the light-incident surface, and a connecting surface coupling between the light-incident surface and the light-emitting surface. Each image compensating element includes a plurality of light guiding channels. Light guiding paths of the light guiding channels extend along a direction from the light-incident surface toward the light-emitting surface.
