Recently, General Secretary Xi Jinping presided over the ninth meeting of the Central Finance and Economics Committee and emphasized that achieving carbon peaking and carbon neutrality is a broad and profound economic and social systemic change, and carbon peaking and carbon neutrality must be included in the ecological system. The overall layout of civilization construction, with the strength to grasp the iron, achieve the goal of carbon peak by 2030 and carbon neutral by 2060 on schedule.
As a major national strategic decision, "doing a good job in carbon peaking and carbon neutrality" has become one of the key tasks of the "14th Five-Year Plan". Of course, the LED display industry, which is closely related to it, cannot stand idly by. So what is carbon peak? Carbon neutral? What are our 2030 and 2060 goals?
Carbon peaking means that at a certain point in time, carbon dioxide emissions no longer increase to a peak, and then gradually fall back. China has promised that carbon dioxide emissions will no longer increase before 2030, and will gradually decrease after reaching a peak.
Carbon neutrality refers to the calculation of the total greenhouse gas emissions directly or indirectly produced by enterprises, groups or individuals within a certain period of time, and through afforestation, energy saving and emission reduction, etc., to offset their own carbon dioxide emissions and achieve "zero carbon dioxide emissions" ". China is committed to achieving carbon neutrality by 2060.
So, how does the closely related LED display industry achieve its carbon peak and carbon neutral goals?
Although the LED display does not directly emit carbon dioxide, the high energy consumption required during production and use indirectly generates a huge amount of carbon dioxide. To solve the problem of carbon peak and carbon neutrality in the LED display industry, it is actually to solve the problem of high energy consumption.
According to statistics, the world produces more than 3.5 million square meters of LED displays every year. Based on the power consumption of 500 watts per square meter, it consumes 1.75 billion kilowatt-hours of electricity each year, which is not even the amount of electricity consumed in the production process. Therefore, some people say that the LED display industry is a big power consumer, and it is not fake at all.
In order to solve the problem of power consumption, Chinese LED display companies have been tirelessly exploring energy conservation. For example, through intelligent manufacturing, rationally improve efficiency and reduce the corresponding carbon emissions; technological innovation within the enterprise, many outdoor LED displays need to rely on air conditioning to assist heat dissipation, now this phenomenon is rare, mainly through structural heat dissipation, and Technical improvement from driver IC, power supply...
At present, the common cathode technology is the most respected. "Common cathode" refers to the use of a common cathode to supply power to the LED display. The current flows through the lamp beads and then to the negative electrode of the IC, which reduces the forward voltage drop and the internal resistance of the conduction. Contrary to the common anode technology, the common anode is where the current flows from the PCB board to the lamp beads, and uniformly powers R, G, and B (red, green, and blue), which causes the forward voltage drop of the circuit to become larger.
For products with the same specifications and with the same brightness, the screen temperature of the common cathode LED display is more than 20 degrees lower than that of the conventional common anode LED display product, and the power consumption is 50% lower than that of the conventional common anode LED display product. the above. Because the common cathode LED display screen has a low temperature, it is also called a cold screen.
From the cost point of view, the current common cathode LED energy-saving display screen will not increase too much than the conventional display screen, and it will save costs in the later use, so it will be the future development trend.
At present, the common cathode technology products are still only a minority, because the supporting industrial chain is not yet mature, the overall volume is not large, and the common anode products still occupy 80% of the market. Recently, Absen launched the Aurora Aurora series common negative screen, fanless design, which saves nearly 40% of electricity bills compared to traditional products. This is a very meaningful attempt in the history of the display industry!
Improvements in materials and processes can reduce energy consumption to a certain extent, but it still cannot completely change the fact that LED displays consume high energy. The goal of carbon peak and carbon neutrality, as the national will, will inevitably be like a "tightening curse" as time gets closer and more restrictive. If the LED display industry cannot tear off the high-energy-consuming labels, it will inevitably affect its widespread application in the future. Therefore, exploring a more energy-efficient display solution will be a must.
Explore solutions to adapt to clean energy and find new energy-saving outlets. With the tightening of non-renewable resources such as coal, solar energy, wind energy and other resources are widely optimistic. Solar energy and LED were once hailed as "a match made in heaven", and solar street lights and garden lights have long been popularized in the countryside. If the LED display can also achieve a "match made in heaven" with new energy sources such as solar and wind energy, and the LED display can be turned into a "solar screen" or "wind energy screen", then the carbon peak and carbon neutral goal is not only not the LED display industry Challenges will also be the new historical development opportunities that the industry faces in the future, and it is also a great thing that will benefit the future.
The goal of carbon peak and carbon neutrality has pointed out the direction for all walks of life. LED display application industries and enterprises can only win their own place in the future if they face difficulties, creatively resolve related problems, and bear the national development vision.
