In recent years, the market for led displays has grown larger and wider. Led display manufacturers are also getting more and more, besides the established famous led enterprises, there is also a lot of poor quality. Although the market is more and more extensive, the competition is getting bigger and bigger. There is good technical competition and bad price war. In order to survive, small new LED manufacturers can move to the market in a low price and quickly open the market and seize a number of customers. But in many cases, because of technology, quality problems cause a series of accidents. And then the client has to spend the time to repair, not to pay. So, the led screen is not a short time tool, it doesn't want a phone, it can change every year. There are all kinds of cheap homebred mobile phone appear on the market, although the technology of lower quality than imported apples, but far more than the apple sales, because cell phones for consumers is a tool for a short period of time, soon changed, don't need to buy than good. But the led screen is different, and it takes a long time, five years, eight years and 10 years. Therefore, low price can not be an important factor for consumers to choose led display. Quality is good, and durability is what really saves money for customers.
Because of LED, IC are semiconductor devices, they are critical of the use of environmental requirements, best at room temperature 25 ℃ or so, its working mechanism is the best. But in fact a outdoor screen will be used in different temperature environment, may be in more than 60 ℃ in summer, winter may be under - 20 ℃. When factory production product is 25 ℃ as test conditions, the different step of product classification, but the fact running condition of 60 ℃ or - 20 ℃, then LED, IC work efficiency and performance, may belong to a becomes more original file, the brightness is not consistent, the screen body is naturally get spent. This is because under the condition of different temperatures, red, green, blue three kinds of the brightness of the light attenuation and drop is different, at 25 ℃, the white balance is normal, but at 60 ℃, the three colors of the brightness of the leds are decreased, and the attenuation values are not consistent, so will produce the whole screen brightness decline and the phenomenon of partial color, the quality of the whole screen will drop. The IC? Working temperature range is in IC - 40 ℃ to 85 ℃. Due to ambient temperature is too high the casing temperature, if the temperature over 85 ℃, IC, because temperature is too high, cause of the work is not stable, or the channel between current extraction and temperature drift or caused by too much difference between flowers screen.
So it is the key that led display can work long hours to ensure its life expectancy. The former maintenance aluminum module is a brand new heat dissipator, super heat dissipating ability, high temperature resistance, radiation resistance and oxidation resistance. Effectively guarantee the normal working of led display screen.
