Environment-friendly and energy-saving LED display screen is a system engineering application that integrates advanced international engineering technologies such as electronic technology, computer technology, electrical technology, optical technology, green environmental protection, light pollution reduction and low power consumption. The project area is large, the projection time is long, and low power consumption has become a concern of users. Key indicators. "Energy-saving and environmental protection" is a link that our country attaches great importance to in recent years. As the fourth media, LED display screen has a large area and a long broadcast time, and its power consumption can be imagined. Green manufacturing industry has become a deep problem for LED display manufacturers. How to achieve green manufacturing is not only a demand of enterprises, but also a trend of future development.

     LED energy-saving display screen needs to adopt the latest international design concept, taking into account the cost and other factors, from the display screen electronic technology, computer technology, electrical technology, optical technology, green environmental protection to reduce light pollution and low power consumption and other international cutting-edge engineering technology system engineering integration application to carry out low power consumption of LED display screen. The design provides a set of large screen energy-saving scheme for customers. Compared with conventional display, energy-saving display not only reduces investment in air-conditioning, cables, power adapters, distribution cabinets and other aspects, but also saves energy and electricity by 70%, with obvious benefits. Compared with the past, the red light brightness of the energy-saving screen has been increased by 125%, which means that the same power consumption and brightness of the display screen are stronger. In addition, the design of synchronous rectifier circuit drives the IC to reduce the power supply voltage under constant current state to achieve better energy-saving effect.

     Of course, energy saving is not only the result of technical improvement of one hardware or software of the display screen, but also the result of technical innovation and team cooperation in the overall scheme.

     Energy-saving products = low-energy LED display:

1. Respond to the call of the state to save energy and reduce energy consumption;

2. Save electricity cost and operation cost to reduce comprehensive use cost.

3. Reduce the temperature of display module and reduce the investment of heat dissipation equipment.

4. Reduce the power consumption of display screen, reduce the input of distribution cable, power adapter, distribution cabinet, etc.

5. Delay the speed of LED attenuation, reduce the temperature drift of the photoelectric parameters of the display screen, stabilize the image effect, improve the reliability of the system and prolong the life of the display screen.

Energy-saving is to reduce electricity consumption, that is, to reduce power consumption and improve energy efficiency ratio; power consumption calculation: power consumption = voltage * current, that is, P = U * I

     To achieve the goal of energy saving, it is mainly to reduce voltage or current.

     To this end, energy conservation is achieved mainly from the following aspects:

1. Unique power supply PCB circuit design to reduce power consumption of affluent voltage;

2. Use high-efficiency LED to reduce the value of LED Vf and current consumption, and improve the luminous efficiency.

3. Using high efficiency constant current drive IC to reduce the loss of driving circuit;

4. New system integration design, with automatic brightness control and other ways, improve the energy efficiency ratio of products in an all-round way.

     Using 3.8V power supply design to optimize PCB lines, high-efficiency LED lights, low-voltage energy-saving driving IC (3.8V power supply), reduce the energy consumption of affluent voltage and heat.

     Product features:

     Design of Minimum Constant Current Voltage 0.15V for Ultra-Low Power Consumption with 70% Power Saving

     High efficiency LED wafer with high luminous efficiency and high luminous intensity and fully automatic packaging are adopted.

     The comparative data are as follows:

     From the above table, energy-saving LED lamps have lower VF value, higher brightness and higher energy efficiency ratio.

     Basic driver IC, VDS value of 0.7V, low conversion efficiency, only 70%, LED brightness efficiency only 70%;

     Energy-saving products use FM-PWM technology, low loss, high refresh rate, high gray scale, high brightness driver chip, driving efficiency of more than 90%.

     LED utilization = T (LED Light On)/(LED Total Time)

     With the same brightness, the higher the utilization of LED, the lower the current required, and the smaller the PeakEMI, the lower the EMI.

     3.8V power supply, brightness remains unchanged

     The brightness of the LED display at www.led-cg.net depends on the current. Constant-current-driven products, whether powered by 3.8V or 5V power supply, have constant output current and uniform brightness after reaching the working voltage. The reliability of 3.8V power supply has been confirmed from the display performance.

     3.8V power supply, more load

     Furthermore, it is the current, not the voltage, that determines the number of loads. Under the condition that the power supply voltage can ensure the normal operation of the screen, the constant current drive product is a current-controlled product, so the load of the product only depends on the current size of the power supply. It uses 3.8V power supply to supply more load, and proves the practicability of 3.8V power supply from the actual use.

     3.8V power supply, more stable screen operation

     Because the normal working voltage of the LED display only needs 3.8V, the excess 1.2V voltage will be consumed by the row drive IC, which will increase the working temperature by 15-35%, and reduce the service life. At the same time, these heat is transmitted to the lamp through the PCB board, which makes the temperature of the screen lamp tube rise accordingly, thus speeding up the lamp tube failure time of the display screen in use. Through the practice test of cold and hot shock test and high and low temperature cycle test, we proved that the reliability and stability of LED display screen can be improved by using 4.5V power supply.
