Case Study: LED Display Modules
In 2025, we partnered with a digital display company to supply 3.0mm dual-row through-hole H9.9mm connectors for their commercial LED panels.
The challenge was that high-resolution displays were prone to instability due to heat dissipation and dense signaling, impacting image quality.
Solution Deployment
We replaced the connectors with optional gold plating and thermal management, achieving a stable 5A output from -20°C to +80°C, a sense impedance of 8mΩ, and 98% efficiency.
Results
After panel deployment, flicker rate decreased by 19%, and brightness increased by 14%.
The company stated that the through-hole design offered superior integration and saved 15% in production. This analysis highlights the product's superiority in the display field, helping customers build high-efficiency modules.
