Bad or good, how to detective LED Display
Now, most of customers choose led display is according to the price, but it’s not reasonable. Today, Harse technology will show you how to detective.
First of all, there was a huge mistake here, most people think that the main material of the LED screen, IC life 100000 hours, 365 days per year, 24 hours/days running, service life is more than 11 years, so most of the customers only care about with well-known LED and IC. Actually both was necessary, rather than sufficient conditions, because red, green, blue three kinds of the rational use of the tubes, more important, to display to the tubes of different colors, to make it work in the best condition, for a good display will be more important. Here is the key factor:
1.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.
2.At the same time, the power supply is also very important, because the power under the condition of different temperatures, the working stability, output voltage and load capacity will also be different, because it's for the logistics function, therefore its ability to directly affect the quality of the screen.
3.Cabinet design for the display screen is also very important, on the one hand, it is the circuit protection, on the other hand is a safe, as well as dustproof and waterproof effect. But more important is whether the ventilation cooling system of hot circuit design is good, with the increase of boot time and outside temperature, the components of the thermal drift also increases, resulting in image quality becomes poor.
therefore, to choose a good screen, first line must choose good tubes, durable, adaptable, and absolutely not despise the assessment of other materials and processes, like cars, a few people in the shop, also can put together a car, in the tens of thousands of factories are in assembling a car, the vehicle driving mileage and security coefficient should be far. Outdoor screen waterproof and resistance to deformation, processing technology and key parts, a miss is as good as a mile.
In addition to consider the quality of the main components such as LED, IC, and the seller's prior communication is also very important. It not only directly affect the quality of the whole project, the success or failure, often can let users more reasonable allocation in resources, avoid unnecessary waste, loss and hidden dangers, and even increase the considerable income.
