Specular Reflection Structure for Seamless Multi-Display Panel Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multi-display panel assembled display devices face the issue of non-display areas at boundaries between panels being visually recognizable, and existing solutions using complex optical systems are either ineffective or increase the size of the display device.
Innovation Solution
The implementation of a specular reflection structure comprising specular mirrors that convert and merge images from multiple display panels into an integrated image, eliminating the non-display areas by reflecting and aligning images without changing their size or content, using a system of specular mirrors in a 1:1 or 1:multiple correspondence to create a seamless display.

Engineering Contradiction Analysis
1Area of stationary object
If multiple display panels are assembled to form a large area display, then the display area is increased and cost is reduced, but non-display areas at boundaries become visually recognizable
Solution Approach 1:
A light guide plate is introduced as an intermediary component between the display panels and the viewer. This plate redirects light from the display panels to fill in the non-display boundary areas, making them visually indistinguishable from the active display regions. The light guide plate acts as a mediator that transforms the visual appearance of the assembled display without requiring changes to the panels themselves.
Solution Approach 2:
The light guide plate utilizes optical properties to modify the visual characteristics of light passing through it. By controlling the distribution and direction of light, the plate creates a uniform appearance across the entire display assembly, effectively masking the boundaries between individual panels through optical rather than physical means.
2Object-affected harmful factors
If a complex optical system is used to remove non-display areas, then the visibility of boundaries is reduced, but the device size increases
Solution Approach 1:
The light guide plate serves multiple functions simultaneously: it redirects light to mask boundaries, maintains the structural integrity of the display assembly, and provides a uniform viewing surface. This multi-functional component eliminates the need for additional complex optical systems that would increase device size while achieving the same boundary-masking effect.
Solution Approach 2:
The invention changes the optical parameters of the display system by introducing a light guide plate with specific refractive and reflective properties. This parameter change allows for thin, integrated boundary masking without requiring bulky optical components, thereby reducing the overall device volume while effectively hiding non-display areas.
3Object-affected harmful factors
If specular mirrors are used to convert display directions, then images are merged into an integrated image, but the optical system complexity increases
Solution Approach 1:
Multiple specular mirrors are combined into a single integrated light guide plate structure. Instead of using separate mirror components for each panel, the invention merges their functions into one unified optical element that handles light redirection for the entire display assembly, thereby reducing component count and system complexity.
Solution Approach 2:
The light guide plate creates optical copies of the light paths that would otherwise require multiple separate mirrors. By using total internal reflection and refraction within the plate, the system replicates the function of multiple mirror assemblies through a single component, simplifying the overall optical architecture.
