1. Adopt high-energy drive chip and design circuit. The LED display chip adopts constant current noise reduction technology to ensure that the influence of other noise source factors such as power supply on the screen body is minimized. And when designing the circuit, taking into account the high-brightness automatic adjustment technology, automatically adjust the brightness of the screen according to different weather and environmental brightness, not only to achieve the best display effect, but also to have the greatest effect on energy saving.

2. Use good, high-efficiency and energy-saving LED lamp beads. There are many LED lamp bead manufacturers at home and abroad, and their product quality is different. Lianchengfa’s cooperative manufacturers are well-known domestic and foreign companies, and have long-term cooperative relationships with internationally renowned companies such as Japan, the United States, and Taiwan. The LED lamp beads of these corporate brands are not only uniform in color, good in consistency, and extremely luminous. High, anti-static ability is also very strong, not easy to die, longer life, more stable performance, although the price is higher than ordinary LED lamp beads, but in the long run, it can save operating costs and achieve the most impact good.

3. Use energy-saving LED power supply. Lianchengfa cooperates with the power supply of a Hong Kong partner. Lianchengfa's power supply is controlled at a power efficiency of 80-88, which is much higher than the 75-80 of ordinary power supplies, and is 5-10 points earlier than the efficiency of ordinary power supplies. How is this done? Most of the ordinary power supplies use the broken bridge circuit, while the Liancheng power supply uses single and double tubes, adding a synchronous vibration current, and the energy saving effect is very good. In addition, the warranty period of ordinary power supplies is generally up to two years, while the quality of Lianchengfa power supplies is at least 3-5 years, which provides more quality assurance products for the majority of users who use Lianchengfa products.
