  Select the full color LED display focus to consider the factors

  In recent years, full color led display market is growing, more and more wide. Full color led display manufacturers are more and more, in addition to the well-known well-known LED business, there are a lot of good enough manufacturers. Although the market is growing, but the competition is also growing. There are benign technical competition, there are bad price war. Small new full-color LED display manufacturers in order to survive, to low-cost attitude to the market, but also quickly open the market, to seize a number of customers. But in many cases, because of technical, quality problems lead to a series of accidents. And then customers have to spend time to repair, more harm than good. So, full color led display it is not a short time tool, it does not want to phone, you can change for a year The reason why there are a variety of cheap domestic mobile phone market, although the quality of technology is less than imported apple, but sales are far more than Apple, because the phone is a short time for the consumer tool, and soon replaced, Need to buy special than good. But full-color led display is not the same, it needs to use a long time, 5 years 8 years 10 years. So the price is low can not become a consumer choice full color led display an important factor. Good quality, durability is really to the customer to save money.

  As the LED, IC are semiconductor devices, their use of the environment requirements critical, preferably about 25 ℃ at room temperature, the best working mechanism. But in fact an outdoor full color LED display will be used in different temperature environment, the summer may be above 60 ℃, winter may be below -20 ℃. When the manufacturers produce products is 25 ℃ for the test conditions, the different products sub-file classification, the actual conditions for the operation of 60 ℃ or -20 ℃, then LED, IC efficiency and performance is inconsistent, may belong to a file The will become a multi-file, the brightness is inconsistent, the screen body also naturally spent. This is because in different temperature conditions, red, green and blue lamp brightness attenuation and decline is different, at 25 ℃, the white balance is normal, but at 60 ℃, the three colors of the LED The brightness has declined, and its attenuation value is inconsistent, it will produce the whole screen brightness and color cast phenomenon, the quality of the whole screen will decline. And IC? IC operating temperature range is -40 ℃ -85 ℃. Due to the outside temperature is too high and lead to the temperature inside the box, if the box temperature exceeds 85 ℃, IC will be because of the high temperature caused by unstable work, or different temperature drift between the channel or the difference between the film is too large Leading to Huaping.
