LED Display System Using Copying for Remote Image Distortion Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Large-size LED display modules in outdoor settings are prone to damage from weather conditions, leading to image distortion, and existing monitoring solutions are costly and difficult to implement in remote or dangerous locations.
Innovation Solution
A light emitting diode display system comprising a first LED display module, a second LED display module, and a control module, where the control module provides control signals to the first driving module to drive the LED units and display images, allowing for remote detection of image distortions by reproducing the image on the second module without the need for additional detecting devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a monitoring device is added to detect image distortion on the LED display module, then the detection capability is improved, but the system cost increases and the complexity of installation increases
Solution Approach 1:
The patent uses a second LED display module to display a copy of the same image as the first module, allowing visual comparison to detect distortions. This copying approach eliminates the need for separate monitoring devices while maintaining detection capability.
Solution Approach 2:
The second LED display module serves dual purposes: it functions as a normal display device while simultaneously serving as a reference for detecting image distortions on the first module. This multi-functionality reduces the need for dedicated monitoring equipment.
2Measurement precision
If a monitoring device is mounted at the remote site of the LED display module, then the detection accuracy is improved, but the installation difficulty and cost increase
Solution Approach 1:
Instead of installing monitoring devices at the remote site, the system creates a visual copy of the displayed image on a second LED display module at the control location, enabling detection without remote installation.
Solution Approach 2:
The second LED display module acts as an intermediary that transfers the visual information from the first module to the control location, eliminating the need for direct monitoring device installation at the remote site.
3Reliability
If additional detecting devices are used to monitor the LED display module, then the detection capability is improved, but the system cost increases
Solution Approach 1:
The second LED display module performs multiple functions: normal display operations and distortion detection reference. This eliminates the need for separate detecting devices, reducing system cost while maintaining detection capability.
Solution Approach 2:
The system uses image copying on the second display module as a cost-effective alternative to expensive specialized detecting devices, achieving the same detection capability through a simpler, cheaper method.
