Affect the use of LED display there are many key factors, such as the quality of the die is good or bad, other components of the production process is good or bad, box and control system design, but there are other factors that are easily overlooked.
Power supply
Power supply in an LED display system is also an important part of the quality of the impact. 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. Can not just look at the low price without looking at its performance and quality to choose.
2. Grayscale
As double color and full color display gray scale is an important indicator. Currently on the market is full of many 16 and 64 gray-scale display posing as 256 gray. Its control costs only 256 gray-scale control of 1/5. The easiest way is to play a more intense sports scene on the VCD to see if the LED display can be seen clearly.
Life expectancy
In the appropriate use of the environment, LED life of up to 100,000 hours, can effectively save the user's maintenance and replacement costs. But many consumers reflect the purchase of their LED products, life expectancy is far from expectations. This is because the market now LED light source brand is very mixed, although some of the price is very cheap but the quality of its components will inevitably be sacrificed. If the user to buy a poor quality LED products are prone to flashing or not bright phenomenon, life and energy efficiency will be greatly reduced.
Box design
Box design on the LED 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 component thermal drift will increase, resulting in poor image quality. Good ventilation design is an essential indicator of box design.
Therefore, the user in the purchase of LED display products, or should choose a regular LED manufacturers, in quality, price, after-sales service, etc., will be more secure, for your follow-up work easily, to buy the best.
