Highlight:

The whole series of LED displays are made of Taiwan imported LED chips. After packaged, they are screened one by one through the LED splitter at the sorting speed of more than 10000 pieces per hour. Through the classification and screening of the wavelength (color), light intensity, current and voltage of the LED, the grade highlight products will be used by our company; the driving part can meet the premise of normal operation of LED, and reduce the number of LED as far as possible Less load, ensure that each LED has surging power output;

Working life:

According to the accelerated aging and life test system test of LED, the initial luminous flux is 100%. When the lumen maintenance rate of LED products drops to 70% or 50% of the initial value, the LED is considered to be invalid and the theoretical life of LED is more than 10W hours. Based on the influence of electronic components around the LED display on its life, through testing the thermal characteristics, environmental weather resistance, electromagnetic compatibility immunity and other performance closely related to life and reliability, the comprehensive analysis shows that the theoretical life of LED display is more than 5W hours;

Fast refresh:

The requirement of high quality LED display screen is not only to have high refresh rate, but also to have the ability of high output color level to achieve more colorful LED display images. Our company's LED display screen and circuit board are all printed with patent technology developed by ourselves. With the driving chip with smaller OE pulse width, it can improve the output gray scale and refresh rate at the same time;

Energy saving and environmental protection:

In the existing LED display screen, our company directly adopts half bridge rectification or full bridge rectification high-efficiency switching power supply, plus synchronous rectifier circuit, the energy-saving effect is remarkable. In addition, through matching and debugging to the best index, the input voltage can be reduced as much as possible under the constant current state of driving IC, and the red, green and blue cores are supplied separately to achieve better energy-saving effect;

Silent operation:

The whole series of LED display screen adopts super silent fan design, which is realized by damping, optimizing motor, improving bearing and fan blade. So as to achieve high heat dissipation efficiency, no noise, no air conditioning, no exhaust fan. In the circuit aspect, the LC filter circuit is matched and debugged to effectively eliminate the current sound caused by poor filtering. Eliminate noise, reduce power consumption, save power and save energy;

Good heat dissipation:

The exposed surface of LED display panel is more than 80% of the heat generated, and most of the heat is naturally emitted to the external space. Using LED insulation heat dissipation plastic as heat dissipator, the heat dissipation fin cover made of LED insulation heat dissipation plastic can keep the heat dissipation capacity equal to that of aluminum alloy, increase the heat dissipation area, and increase the thermal radiation capacity by 4-8 times. The special shape of the mask is used to produce convective air, which is the lowest cost way to strengthen heat dissipation;

Beautiful color:

It adopts the self-developed shadow elimination circuit to completely eliminate the bad phenomena such as dark light, dragging shadow and flicker. It is made of high-quality raw materials such as high brightness LED chip, high brush driving IC and excellent control system. The display effect of LED display screen is better when the refresh frequency is more than 1800hz. The picture is beautiful and natural because of the uniform color, high contrast, high color level and high refresh.
