Solution for Advertising LED Displays
Requirements for advertising LED display
- Strong protection to withstand extreme weather conditions
- Energy saving to lower power consumption and save operational cost
- High brightness to ensure clear pictures even in the sunshine
- Wide viewing angle to cover larger view range and attract more attention from passersby
- Uniform and stable pictures to keep outstanding performance
- Long life span to maximize the benefits of customers for 5 to 8 years or even longer life span
Technical solution for advertising LED display
1. High-quality Components
- LED lamps: High brightness LED lamps with wide viewing range and low driving current, consuming less power.
- Driving IC: High-precision constant current LED driving ICs with current gain control; the light decay can be controlled to maintain a stable brightness.
- Power supply: With PFC (Power Factor Correction) function to improve the efficiency of power supply, produce less heat, and save energy.
- Optical fiber: Shortening signal delay caused by long distance transmission.
2. Advanced Control Technology
- Calibration: Pixel-by-pixel brightness and color calibration technique to keep uniform brightness and natural colors of LED display.
- Monitoring: Proprietary control system can monitor the temperature, brightness, status information of LED display in real time.
- Remote network control: Controlling and changing all display information, controlling the displays of several cities in one place to change the contents at any time, and turning on and off the power of LED display at any time or a fixed time.
- Adjustable brightness: Adjusting screen brightness automatically according to environmental lighting based on sensitive control system, adjusting it manually or by programmable menu.
- Double backup system: When one control system falls into malfunction, the other one will back up and start work immediately.
- Large screen control: Controlling super large size display stably without any black screen, frame vibration or reducing.
- High refresh rate, high gray scale and high contrast ratio: More realistic pictures optimize commercial advertisement value. And our patented mask design avoids direct sunlight and dirt deposition to improve contrast.
3. Effective Solution
- Energy saving: Adopting the techniques of LED lamps with low driving current, adjustable brightness, efficient power supply with PFC, less heat dissipation, special cooling design, and appropriate power distribution from control system.
- Cooling design: With special designs of 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.
- Long life span: Benefiting from the techniques of energy saving design, high quality LED lamps, effective cooling design, adjustable brightness, all-round protection, and efficient power supply with PFC.
- Protection: IP65 standard cabinets to protect LED display in extreme weathers; famous brand anti-lightning device to avoid lightning shock; the protective layer of our special conformal coating on PCB board to resist hostile environment.
The following are the topological diagram of the LED display system and the block connection diagram of cabinets.
