Analysis of the factors that maintain the LED display can work normally

LED display of the ambient temperature is very critical, theoretically at about room temperature 25 ℃, the best of their work status
     But in fact, outdoor led screen applications in ambient temperature is quite complex, maximum temperature in summer may be more than 60 ℃, the lowest temperature in winter may be below -20 ℃. LED, IC efficiency and performance is inconsistent, brightness inconsistent, Screen overall natural variability spent also displayed. At different temperatures, red, green, and blue light brightness decay and fall is different, at 25 ℃, the white balance is normal, but at 60 ℃, three-color LED brightness are decline, and its attenuation value is inconsistent, it will produce the entire screen brightness down and cast the phenomenon of the entire screen quality will drop.

    IC operating temperature range is -40 ℃ -85 ℃. Because the outside temperature is too high and lead to the cabinets temperature, if the inside temperature exceeds 85 ℃, IC is because the temperature is too high and lead to job insecurity, or drift arising between different channel current or tablets difference between too large resulting in the video. Domestic LED display manufacturers are trying to carry out a number of improvements in design, workmanship, can effectively control the external environment temperature on the display of the final result, as much as possible so that the led screen perfectly displayed in a variety of complex conditions.
 
The importance of power
     Power in a LED display system also affect an important part of quality. Since the power supply under different temperature conditions, their job stability, output voltage and load capacity will be different, since it bears a logistical role, its ability to protect the direct impact on the quality of the screen. Depending on the performance and stability of different brands and specifications of the power supply equipment prices also have this considerable difference. Not just look at the low price without looking at its performance and quality to choose.
 
The key factor in the design of the housing
     For the display cabinet design is very important, on the one hand it is a circuit protection, on the other hand is the role of security, as well as dust-proof, waterproof. But more important is the thermal loop ventilation system design is good, with the power to extend the time and outside temperature, the thermal drift components will increase, resulting in deterioration of image quality. Good ventilation design is an essential indicator of housing design.
 
The importance of the production process
     Is an important part of the production process to ensure product quality LED display, LED display production process to maintain absolute static treatment, to ensure that the wafer is not damaged.
 
The importance of brands
     A well-known brand in the market over a long period of hard work to get social recognition. Enterprises depending on brand for life, will never be easy for short-term interests and hurt their brand image. Some small companies is not high profile company or, in this respect, no scruples. Sometimes short-term gain at the expense of his own reputation, and damage to customer behavior. Therefore, the choice of brand-name suppliers, quality assurance is helpful.
