When buying an LED display, everyone is eager to choose a satisfactory, high-quality and inexpensive LED display. However, many people are more or less caught up in some misunderstandings about screen selection when purchasing.

 
 

1. If you want to buy, you must be the best: First of all, the purchase of LED displays must be combined with your own actual situation. While meeting your needs, you must also have a certain advanced idea, but you can't blindly pursue the best. Although the expensive ones are generally better, it depends on whether you can symmetrical your use and your own economic situation. Otherwise, you will only waste more money on functions you don't need.

 

2. National standards and industry specifications: The general specifications for LED displays were part of the standards in the 1990s, and now it is 2017. Looking back at the previous standards, too many changes have taken place. Take an example, the out-of-control point, the national standard is 5/10,000, take indoor dual-color LED display as an example. Generally, a 740480 standard resolution display screen is 10 square meters, and each square meter is 42465 points. According to the national standard, there can be 120 out of control points. However, in the fast-developing modern life, no one will buy such an LED screen.

 

 

3. Free software and low price: The current Chinese companies have a common problem, that is, only production but not research and development. The same problem exists in the current LED display industry. At present, only a few LED display companies have their own genuine software, and many people may not know that it is illegal to use pirated editions now. Low price is good, but it is not necessarily what we want. More importantly, it is cost-effective. If you buy the right one, you don't necessarily buy the one with a low price. This is more difficult to distinguish.

 

4. Grayscale: Grayscale is an important indicator of LED display screens. At present, the market is flooded with many 14-level and 80-level grayscale displays pretending to be 256-level grayscale displays. The cost of the former may only be 256-level grayscale. A small part of the degree. Here is a simple way to tell friends, that is to play a video of a more intense sports scene and check whether it can be seen clearly on the LED display.

 

5. Long life span: The technical data issued by the LED display manufacturer clearly stated that the life span of the LED luminous body is 10,000 hours in an ideal state. This ideal state refers to the time it takes for the LED luminous body to emit light to no light at all under the constant voltage and constant current state in the laboratory. 10 million hours is equivalent to 11 years. We all know that the amount of water in a wooden bucket is determined by the shortest wooden board. LED displays currently use most of the electronic components of average quality, and the service life is usually not more than 10 years, so be sure when you buy it. Keep your eyes open.
