Modular Display Gap Structure With 3D Light-Absorbing Layer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In modular display devices, the gap between display modules can cause a lattice pattern to be viewed due to diffused reflection, leading to degraded image quality and a perceived gap that disrupts screen continuity.
Innovation Solution
A modular display device is designed with a light absorbing layer that includes a first portion on the substrate surface, a second portion in the gap between modules, and a third portion on the opposing substrate surface, ensuring flatness and improving adhesive force between modules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a light absorbing layer is provided only in the gap between display modules, then the gap can be filled, but the light absorbing layer necessarily has a convex or concave shape that degrades its function
Solution Approach 1:
The light absorbing layer is extended from a two-dimensional surface layer into a three-dimensional structure by adding a third portion that protrudes toward the viewer. This dimensional extension allows the layer to fill the gap volume while the first and third portions maintain flat surfaces, resolving the contradiction between gap filling and flatness maintenance.
Solution Approach 2:
The light absorbing layer is nested within the gap structure, with the second portion fitting into the gap space between modules while the first and third portions extend outward to maintain flat surfaces. This nesting approach allows the layer to occupy the gap volume without creating convex or concave deformations on the visible surfaces.
2Area of stationary object
If the light absorbing layer has a convex or concave shape, then it may fill the gap, but the function of the light absorbing layer is degraded and the gap is still perceived
Solution Approach 1:
Different portions of the light absorbing layer are assigned different spatial positions and functions: the first portion maintains a flat surface for optimal light absorption without reflection, the second portion fills the gap volume, and the third portion extends toward the viewer to mask the gap. This local differentiation resolves the contradiction between gap coverage and elimination of harmful optical effects.
Solution Approach 2:
By extending the light absorbing layer into the third dimension with the protruding third portion, the invention creates a volumetric solution that fills the gap while maintaining flat outer surfaces. This dimensional approach allows the layer to occupy gap space without creating the convex or concave shapes that cause diffused reflection and visible gaps.
3Area of stationary object
If multiple display modules are combined into a module type, then a large-area display can be implemented, but gaps between modules create lattice patterns and reduce screen continuity
Solution Approach 1:
The light absorbing layer acts as an intermediary substance that fills and masks the gaps between display modules. By positioning this layer at the interfaces between modules, it mediates the visual discontinuity caused by gaps, preventing lattice patterns while allowing the modules to remain physically separate for manufacturing and assembly purposes.
Solution Approach 2:
The light absorbing layer utilizes light-absorbing materials (typically black or dark-colored) to mask the gaps between modules. By applying this colored layer at the gap interfaces, the visual discontinuity is eliminated as the dark color absorbs stray light and creates a uniform appearance, allowing large-area displays to maintain screen continuity.
