Inorganic LED Module Cover Structure for Seamless Large Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display technologies, such as liquid crystal panels and OLED panels, face issues with slow response time, high power consumption, and susceptibility to burn-in, making them unsuitable for compact and durable display solutions, while inorganic LED panels offer self-emissive capabilities but require innovative structural support for large-sized displays.
Innovation Solution
A display apparatus comprising a substrate with mounted inorganic LEDs, a cover, and a side surface member that absorbs light, providing structural support and minimizing seam visibility between modules, allowing for efficient light management and improved display unity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a cover is extended outward beyond the mounting surface to improve display unity and reduce seam visibility, then the aesthetic appearance and module integration are improved, but the structural support and stability become insufficient
Solution Approach 1:
A side surface member is introduced as an intermediary component between the extended cover and the mounting surface. This member provides the necessary structural support and stability to the extended cover region, preventing deformation while maintaining the aesthetic benefit of the extended cover design for improved display unity
Solution Approach 2:
The side surface member is formed using a light-absorbing material that provides both mechanical support and optical functionality. This composite approach ensures the extended region maintains structural integrity while preventing light leakage and maintaining visual uniformity across multiple display modules
2Area of stationary object
If multiple display modules are arranged in a matrix to achieve large-sized display, then the display size and resolution are improved, but the seam visibility and display unity deteriorate
Solution Approach 1:
The cover is designed with different functional regions: a first region that extends outward beyond the mounting surface to cover gaps between adjacent modules and reduce seam visibility, and a second region that covers the mounting surface itself. This local differentiation allows the cover to simultaneously address both display unity and module functionality
Solution Approach 2:
The extended first region of the cover acts as an intermediary element that bridges the gaps between adjacent display modules. By extending outward to cover these gaps, the cover mediates the visual discontinuity caused by module seams, creating a unified large-sized display appearance
3Shape
If the cover is extended outward to cover gaps between modules, then the seam visibility is reduced, but the light management and potential light leakage become problematic
Solution Approach 1:
The side surface member is formed using a light-absorbing material that appears dark or black in color. This color characteristic allows the extended cover region to effectively absorb any light that might leak from the gaps between modules, converting potential harmful light leakage into absorbed energy and maintaining display uniformity
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 enables a compact, durable, and high-resolution display with reduced power consumption and no burn-in, achieving seamless integration of inorganic LEDs in a large-sized display format.
Implementation Method 1
a side surface member provided on the side surface and arranged below the cover in a direction in which the mounting surface faces. The cover is arranged farther outward than the mounting surface in a direction in which the mounting surface extends, and the side surface member is provided to be bonded to a lower surface of a region of the cover that extends farther outward than the mounting surface and at least a part of the side surface. The side surface member may include a material that absorbs light.

AI summary
A display module includes a substrate including a mounting surface on which a plurality of inorganic LEDs are mounted and a side surface orthogonal to the mounting surface; a cover which is disposed on the mounting surface, and is configured to cover the mounting surface and extend to an area outside the mounting surface; and a side surface member provided on the side surface, and configured to be bonded to a lower surface of a region of the cover that corresponds to the area outside the mounting surface and to at least a part of the side surface.
