Product Introduction

The Anti-oxidation LED digital tube is built using premium LED chips, corrosion-resistant metal frames, and reinforced optical encapsulation resin. These materials and structures significantly improve resistance to environmental oxidation, moisture exposure, temperature fluctuations, and long-term luminous decay.

Conventional LED digital tubes often experience brightness reduction and pin oxidation after long-term usage. However, this advanced model integrates an anti-oxidation protective layer on the lead frame and adopts a high-stability chip packaging process, ensuring uniform brightness and long-lasting performance.

With excellent visibility, low power consumption, and a wide viewing angle, the Anti-oxidation LED digital tube provides highly stable numeric display output in both consumer and industrial electronic systems. It is available in multiple colors, digit heights, and segment configurations to meet various product design requirements.
