At present, LED electronic display has been widely used in the market, no matter you walk in the streets, or the bustling downtown can see LED electronic display figure.  Although LED display has been popularized, but many customers do not understand the common sense of LED electronic display, the following editor on some quality factors of LED electronic display to introduce you, I hope to give you a reference in the purchase of products.

 

First, the impact of temperature on LED electronic display: full-color LED display is very picky about the ambient temperature, theoretically at room temperature of about 25℃, its working state is the most ideal. But in fact, in the application of outdoor LED display, the environmental temperature is quite complex, the highest temperature in summer may be above 60℃, the lowest temperature in winter may be below -20℃. LED, IC work efficiency and performance is not consistent, brightness is not consistent, the overall display of the screen is naturally changed. 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, can produce the whole screen brightness down and slant lubricious phenomenon, and then the whole piece of the quality of the LED display will drop.

　　

Two, the influence of IC: IC operating temperature range is in -40℃ - 85℃.  Because the outside temperature is too high and lead to the temperature rise in the box, if the temperature in the box exceeds 85℃, IC will be too high because of the temperature and lead to unstable work, or different temperature drift and channel current or the gap between the sheets is too large and lead to screen.  Domestic LED display manufacturers are trying to improve the design and process, can effectively control the impact of external environmental temperature on the final effect of the display, as far as possible to make the full color LED display can be perfect in a variety of complex conditions.

 

 Three, box design: good ventilation and heat dissipation design is a necessary index of box design.

 

 Four, power supply: power supply in LED electronic display system is an important link that affects the quality.  Due to the power supply in different temperature conditions, its work stability, output voltage value and load capacity will be different, because it is responsible for logistics support, so its support ability directly affects the quality of LED display.  The power supply equipment of different brand and specification, price difference is very big, when we choose and buy, cannot take a fancy to low price only and do not look at its performance and quality to choose.

 

 LED electronic display manufacturers are many, many customers in the purchase of products are very difficult, do not know how to choose, especially the choice syndrome of customers.  Now, the above points of LED display quality factors sorted out by editor can be used as a reference for your product purchase, hurry to collect it!
