| Unique requirements of the LED display for commercial advertisement | | | |
| | | | | | | | | |
| The LED display for commercial advertisement is customized for the companies engaging in outdoor advertisement. It is suitable for play commercial advertisement in outdoor environment. According to its basic requirements, it has the following main technical features: |
| | | | | | | | | |
| Demanding strong protection. Most of the LED displays for commercial advertisement are operated in outdoor environment, they must be working well under the extreme weather or condition, Therefore, it must have strong ability of waterproof and protection against strong wind, thunder, lightning, high temperature, low temperature and corrosion. |
| Long time running. The LED displays for outdoor advertisement are usually running from 6 o’clock in the morning until midnight without any break. |
| Long lifespan. To maximize the benefit of the customers, the LED displays must have a long lifespan of 5 to 8 years in general, or even longer. |
| Energy saving. The common LED display consumes lots of electricity, if it works without good saving measures, the operational cost of electricity will be very high. No advertising companies would like to see that happens. |
| High brightness. Especially the spectators need to see the picture on the LED display clearly in sunshine from a certain distance, so the brightness of the display must be high enough. |
| Wide viewing angle. To increase attraction for viewers and passersby, the LED display need wide viewing angle to capture the attention of any passerby from 10 meters to 1000 meters. |
| Excellent uniformity and stability for pictures. Lots of advertisements are showed in the way of pictures, so the pictures must be showed evenly and stably on the LED display. |
| Well appearance for long. The LED display must long maintain in a good appearance and prevent from getting worse quickly by the effect of light decay and color fading. |

| Technical solution for commercial advertisement | | | | | |
| | | | | | | | | |
| Based on the above unique requirements of the LED display for commercial advertisement, our technical solution is shown as following： |
| | | | | | | | | |
| Using super-high brightness LED lamps with wide viewing angle and low driving current，the LED display is designed to work in the underloaded condition, so it can be long used and sustained with wide viewing angle and energy saving. |
| Using the constant current LED driving ICs with current gain control, the light decay of LED lamps can be controlled to maintain a stable brightness, the brightness and power consumption can also be automatically adjusted in different time. These technical measures will keep the LED display working stably and the brightness adjustable to prolong the lifespan and energy-saving. |
| The pixel pitch of our LED display for outdoor advertisement have a range of PH10、PH10+、PH16、PH20、PH20+、PH25、PH25+、PH30、PH30+ etc，to meet the viewing range from10 meters to1000 meters for the advertising picture on the LED display. |
| Using our pixel by pixel brightness and color correction technique, the brightness and chrome of the LED display can be adjusted onsite through a period of time. This measure can keep the continuous uniformity of the brightness and chrome of the LED display, and ensure the LED display working in good conditions for a rather long time. |
| Using switch power supply with PFC (Power Factor Correction) to improve the efficiency of the power supply and save the energy. |
| Combined with specially designed control circuit, our system control software can monitor the temperature, brightness, status information of the LED display. This can make the distribution and usage of power consumption more appropriate to realize energy saving. |
| Processed with our special conformal coating，the PCB circuit boards are cured into a transparent protective layer, with excellent insulation and protection ability to against moisture, electric leakage, shock, dust, chemicals, corrosion, UV, aging, electric corona, extreme temperature and other properties. |
| Using conforming to IP65 standard cabinets and decorative protecting box, the LED display can work well in extreme weather. |
| With special designs to separate driving ICs and LED lamps on the PCB, thermal radiator, air flow, ventilation and air conditioning, the LED display could keep working in an appropriate temperature state. |
| Protection to thunder and lightning. Choosing famous international brand of anti-lightning device to eliminate the occurrence of thunder and lightning shock to the LED display |
