LED Module Layout Prevents Border Artifacts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tricolored LED display screen layouts result in blue lines at neighboring borders when modules are rotated, affecting the display effect and requiring the production of four different modules, which increases design and production costs.
Innovation Solution
An LED display screen layout method where each module consists of four tricolored LED lamps arranged in a square by sequentially rotating one lamp by 90 degrees, allowing for seamless splicing and rotation without blue lines, with modules being detachable and easily replaceable.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If uniform arrangement of tricolored LED lamps is used, then production process is simple, but blue lines appear at neighboring borders when modules are rotated
Solution Approach 1:
The patent applies asymmetry by arranging the four tricolored LED lamps in each module at different orientations (0°, 45°, 90°, 135°) rather than uniform alignment. This asymmetric arrangement ensures that when modules are rotated and spliced, the LED lamp directions align properly across module boundaries, preventing blue line appearance while maintaining a simple production process using identical modules throughout.
2Object-affected harmful factors
If four different LED display modules are designed to solve blue line problem, then blue lines are eliminated, but design and production cost increases greatly
Solution Approach 1:
The patent applies universality by designing a single standardized LED module that can be used in all positions and orientations on the display screen. The module contains four tricolored LED lamps arranged at specific angles (0°, 45°, 90°, 135°), allowing the same module type to be rotated and spliced without producing blue lines. This eliminates the need to design and produce four different module types, significantly reducing design and production costs while maintaining display quality.
3Ease of repair
If LED modules are made detachable and pluggable, then replacement is simple, but connection reliability may be reduced
Solution Approach 1:
The patent applies segmentation by dividing the LED display screen into independent, detachable LED modules that can be easily removed and replaced. Each module contains four tricolored LED lamps fixedly connected in a specific asymmetric arrangement. The modules are designed with pluggable connections for simple installation and maintenance, while the fixed internal connections of the four LED lamps within each module ensure reliable signal transmission and maintain connection stability despite the detachable module design.

AI summary
The present invention discloses an LED display screen layout method, including an LED display screen, wherein the LED display screen is formed by splicing a plurality of LED modules; each LED module includes four tricolored LED lamps; the four tricolored LED lamps form a square; and the four tricolored LED lamps are arranged in directions formed by sequentially rotating one of the tricolored LED lamps by 90 degrees. With such layout design, when the LED display screen is rotated, no blue line appears at neighboring borders of the LED modules, thus not influencing the display effect of the display screen.
