Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complexity of wiring structures between driver chips and LED display panels in existing LED display systems, due to mismatched output pins, leads to inefficient data assignment and increased complexity.
Innovation Solution
A driver circuit with adjustable output channels grouped into multiple channel groups, allowing flexible data assignment and operation modes, including inverse sequences, to simplify the wiring structure and align with different LED arrangements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the output pins of the driver chip are not consistent with the arrangement of the LEDs, then the wiring structure must include jumper wires and cross-layer wiring, but this increases the device complexity and reduces ease of manufacture
Solution Approach 1:
The patent implements multiple operation modes that can be dynamically selected based on the LED arrangement. The driver chip can switch between different data assignment modes (first operation mode with first sequence, second operation mode with second sequence) to adapt to different LED layouts, making the wiring structure flexible rather than fixed and complex
Solution Approach 2:
The patent changes the parameter of data assignment sequence based on the operation mode. By switching between first sequence and second sequence for data transmission, the driver chip can match different LED arrangements without requiring complex physical wiring modifications, thus reducing wiring complexity while maintaining adaptability
