Solution Overview
Problem
Display devices face issues with static electricity, moisture penetration, and visible seams between adjacent display modules, which can affect their performance and lifespan.
Innovation Solution
A display device and tiled display device design that includes a side link line, side coating layer, side protective layer, and side sealing layer to prevent static electricity and moisture ingress, while minimizing visible seams by absorbing light and filling gaps between modules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If display modules are arranged in a grid to implement a large screen, then the display area is increased, but static electricity and moisture can penetrate into the sides of the display modules
Solution Approach 1:
The patent divides the side protection into multiple segments: a side coating layer, a side protective layer, and a side sealing layer. Each layer performs a specific function (light absorption, static electricity prevention, moisture sealing) to collectively protect the display module sides while maintaining the grid arrangement for large screen display.
Solution Approach 2:
The patent introduces intermediary protective layers between the external environment and the display module sides. The side coating layer, side protective layer, and side sealing layer act as intermediaries that block harmful factors (static electricity and moisture) from penetrating into the display modules while allowing the grid arrangement to remain intact.
2Ease of manufacture
If gaps between adjacent display modules are left open, then manufacturing and assembly are simplified, but light incident into the gaps creates visible seams
Solution Approach 1:
The patent applies a side coating layer that absorbs light incident into the gaps between adjacent display modules. This coating layer changes the optical properties of the gap region by absorbing stray light, thereby preventing visible seams while maintaining the simple gap structure for ease of manufacturing and assembly.
3Reliability
If protective layers are added to cover the sides of display modules, then static electricity and moisture penetration are prevented, but device complexity increases
Solution Approach 1:
The patent designs the side protective structure with multi-functional layers: the side coating layer absorbs light and provides aesthetic uniformity, the side protective layer prevents static electricity penetration, and the side sealing layer prevents moisture penetration. Each layer serves multiple purposes, reducing the need for additional separate components and minimizing overall structural complexity while maximizing protection and reliability.
