LED large screen is a relatively common display product, which is very common in our daily life, such as outdoor, indoor advertising screen, large screen in conference room, large screen in exhibition hall, etc., LED large screen is used in many occasions. Here, many customers do not understand the purchase of LED large screens. Next, from a professional perspective, Xiaobian will analyze what factors you need to pay attention to when purchasing LED large screen:.

1. Don’t just look at the price when purchasing LED large screen

For many layman customers, the price may be an important factor affecting the sales of LED large screens, and will usually close to the lower price. If there is a large price difference, it will inevitably cause many customers to ignore the product quality. However, in the actual use process, the difference in price is actually the difference in quality in many cases.

2. Production cycle of LED large screen

When many customers buy large LED screens, they need to ship them immediately after placing an order. Although this feeling is understandable, it is not desirable because the LED large screen is a customized product, which needs to undergo at least 24 hours of testing and inspection after production. Many LED large screen manufacturers have added 24 hours on the basis of the national standard, and achieved 72 hours of uninterrupted detection and test, so as to better ensure the working stability of follow-up products.

3. The higher the technical specification parameter value, the better

Generally, customers will select several manufacturers for evaluation when purchasing LED large screens, and then determine the suppliers of LED large screens after comprehensive analysis. In the evaluation content, two important items are price and technical parameters. When the price is similar, technical parameters become the main factor. Many customers believe that the higher the parameter value, the better the quality of the LED screen. So in fact, isn’t that the case?

For a simple example, it is an indoor P4 full-color display screen, in terms of the brightness parameters of the display screen. Some manufacturers will write 2000cd/m2, while others will write 1200cd/m2. In other words, 2000 is no better than 1200. The answer is not necessarily, because the brightness requirements of large indoor LED screens are not high. Generally, they can meet the display requirements above 800. If the brightness is too high, it will be more dazzling, affecting the viewing experience and not suitable for long-term viewing. In terms of service life, too high brightness can easily overdraw the life of the display and increase the rate of broken lights. Therefore, reasonable use of brightness is the positive solution, not to say that the higher the brightness, the better.
