What is the full-color LED display quality factors influence?

As a new generation of display media, full-color LED display with clear screen, color uniformity, high brightness advantages, has been widely used in various industries, such as: exhibition, ports, airports, railway stations, bus stations, major sports and exhibition venues , intelligent transportation, highways, banks, advertising, electricity, commerce, telecommunications, hospitals, taxation, banking, trading markets, public squares and other related systems and almost all industries. But LED display is easy in use by a number of external factors, so that the display quality problems, following Merry Light photoelectric analyze the following three aspects.

1. Power supply
In an LED display system power supply is also affected an important part of quality. As the power under different temperature conditions, the stability of its work, the output voltage and load capacity will be different, because it bears a logistical role, so it's a direct impact on the ability to protect the quality of the screen. Due to the different performance and stability, different brands and specifications of the power equipment prices also have this pretty big difference. Not just look at the cheap without looking at its performance and quality to choose.
2. Cabinet design
LED display on the cabinet design is very important, on the one hand it is a circuit protection, on the other hand the safety purpose, as well as dust and 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 of components will increase, resulting in poor picture quality. Good ventilation is essential indicators designed cabinet design. 3. Temperature
Theoretically LED display ideal working conditions maintained at about room temperature 25 ℃, due to the display of the ambient temperature is very picky, outdoor LED display is relatively complicated in application ambient temperature, the maximum temperature in summer may be more than 60 ℃, the lowest temperature in winter could be in the -20 ℃.
At different temperatures, red, green, and blue light brightness and decreased attenuation is different, at 25 ℃, the white balance is normal, but at 60 ℃, the brightness of the three colors LED are decline, and its attenuation values ​​are inconsistent, it will produce the entire screen brightness down and cast the phenomenon, the quality of the entire screen will drop.
For this reason, LED display manufacturers are trying to Merry Light  lot of improvements in design, workmanship, can effectively control the temperature of the external environment on the display of the final results, as much as possible so that the LED display can be in a variety of perfect display under complex conditions
