What is an energy saving led display, and how does it differ from a traditional LED display?
JunChen Display’s energy saving led display is a next-gen digital screen engineered with core technologies like common cathode design, dual-voltage power supplies, and high-efficiency driver ICs. Unlike traditional LEDs that waste energy via a 5V uniform power supply, JunChen’s models deliver precise voltage to red (2.8V), green (3.8V), and blue (3.8V) LEDs, cutting energy use by 30–50% while maintaining vivid image quality.

Which technology offers better durability and impact resistance?
COB Mini LED displays provide 3-5 times better impact resistance compared to SMD displays. The direct chip integration and epoxy encapsulation make COB displays virtually immune to pixel damage from physical impact, making them ideal for high-traffic environments and mission-critical applications.
42
What is the main difference between COB and SMD Mini LED technology?
The core difference lies in the packaging method. COB (Chip-on-Board) directly integrates LED chips onto the PCB substrate, while SMD (Surface Mount Device) packages individual LED chips before soldering them to the PCB. This fundamental difference gives COB displays superior durability and reliability.
