First of all, the complexity of the temperature on the LED large screen a great impact. The ambient temperature is very picky, theoretically at room temperature 25 ℃ or so, its working condition is the best. But in fact, the outdoor LED large screen in the application of the ambient temperature is quite complex, the maximum temperature in summer may be above 60 ℃, the minimum temperature in winter may be below -20 ℃, in this fluctuating temperature of the LED large screen Quality has a great impact. In different temperature conditions, red, green, blue three kinds of lamp attenuation and decline is different, at 25 ℃, the white balance is normal, but at 60 ℃, the three colors of the LED brightness are And the attenuation value is not consistent, it will produce the whole screen brightness drop and color cast phenomenon, the quality of the whole screen will decline, and high temperature, LED large screen will be because of the high temperature and lead to work instability , Or the temperature drift varies with the flow between the channels or between the film is too large and lead to Huaping. So that the constant temperature is very important. LED display
Followed by the importance. As the power supply in different temperature conditions, its work stability, output voltage and load capacity will be different, because it is responsible for the role of logistics support, so its ability to support a direct impact on the quality of the screen. Due to the different performance and stability, different brands and specifications of the power supply equipment prices have this considerable difference. So in the choice, we must pay attention to the power and performance match. Indoor full color LED display
Finally, the box design for the display is very important, on the one hand it is the role of circuit protection, on the other hand is the role of security, as well as dust, water. But more importantly, the ventilation and heat of the thermal circuit system design is good, with the boot time and the external temperature increases, the thermal drift of components will increase, resulting in poor image quality. Good ventilation design is an essential indicator of box design. However, for some high-profile large-screen enterprises, enterprises as the brand for life, will not easily for short-term interests and hurt their own brand image.
