Say goodbye to blindly choose LED display, the key factors to consider here -
Full color LED screen - knowledge
In recent years, the led display market is more and more big, more and more wide.
Led display manufacturers more and more, in addition to the old famous led enterprises, there are many others small manufacturer.
Although the market is more and more widely, but the competition is becoming more and more big.
There are benign technological competition and adverse price war.
Small new LED manufacturers in order to survive, to the market with cheap attitude, also can quickly open the market, grab a group of customers.
But a lot of cases, however, because of technology, quality problems lead to a series of accidents.
Then customers and want to spend time to repair, do more harm than good.
So, led display, it is not a tool for a short period of time, it is not like mobile phones, can be a change in a 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 led display is different, it needs to use for a long time, 5 years 8 in 10 years.
So low price must not become the important factor of consumer choice led display.
Good quality and durability is real to the customer to save money.
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 in -
Below 20 ℃.
When factory production product is 25 ℃ as test conditions, the different step of product classification, but the fact is 60 ℃ or - running conditions
20 ℃, then LED, IC work efficiency and performance, may belong to a becomes more original file, the brightness is not consistent, screen, but natural 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.
Working temperature range is in - IC
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 the shenzhen science and technology think heat faster, is the led display can work for a long time, the key to ensure the desired life.
Science and technology research and development production of former maintenance module is a new aluminum radiator artifact, strong cooling capacity, high temperature resistance, radiation resistance, oxidation resistance.
Effectively guarantee the normal work of the led display.
