What should be paid attention to when buying large led screens?


1. When buying an LED screen, don't just look at the price. Price may be an important factor affecting the sales of led large screens. Although everyone understands the principle of value for money, when you choose an LED screen manufacturer, you will still unconsciously move towards a lower price.

Huge price differences make consumers ignore quality. However, in actual use, maybe just remember that the difference in price is the difference in quality. 2. The same type of large-screen LED may not necessarily be the same type of product. When I am promoting LED large-screen products, I often meet customers and ask me why the price of your products of the same model is much higher than others.

In fact, I was shocked because I was quoting the client based on the price from the company channel. Accidentally found that the so-called products of the same model were different. Take the P4 LED screen as an example.

Generally speaking, the pixel pitch of a P4 LED screen is 4.0mm, but there is only one 4.81mm on the market. Some customers who don't know the outside situation use the salesperson's eye mask to claim to be a P4 full-color LED screen. This kind of quotation gap is more obvious, and many customers who do not know each other think that they have bought a good product at a low price.

3. The technical specification parameter value is not as high as possible. Under normal circumstances, customers who purchase LED screens will choose some manufacturers for evaluation, and then determine the supplier of LED large screens. Two important items in the evaluation are price and technical parameters.

In the case of similar prices, technical parameters become winners and losers. Many customers think that the higher the parameter value, the better the display quality. Is this really the case? To give a simple example, it is also an indoor P4 full-color LED screen, the brightness value of the LED screen.

Some manufacturers write 2000cd/square meter, while others write 1200cd/square meter. Is 2000 better than 1200? The answer is not necessarily, because the brightness requirements of indoor LED screens are not high, usually between 800-1500. Excessive brightness will dazzle the eyes and affect viewing.

In terms of lifespan, too high brightness is easy to overdraw the lifespan of the display in advance. Therefore, reasonable use of brightness is the correct answer, not to say that the higher the brightness, the better. The same model requires parameters such as the brand/package of the LED light, scanning method, power update rate, power consumption, and grayscale.

Different parameters have different prices. 4. The production and testing time of the LED screen is not short. Many customers who buy led screens just place an order and want to get the goods right away.

We understand this mentality very well, the large LED display is a customized product, and it needs at least 48 hours of inspection and testing after the production is completed. Standard LED screen is added for 24 hours to realize 72-hour uninterrupted detection. There are generally two problems with short lead times.

One is that it has not passed sufficient testing and testing, and the failure rate in future use is very high, but some manufacturers do not have enough stocks of the same batch. This may be the use of different batches of product in order to accept the order. In this way, the display has obvious chromatic aberration, which seriously affects the display effect of the LED.
