Want to buy a large outdoor led display board, 30 square meter, how much is the cost? looking for led screen supplier USA
, what i need to know before buying led screens?
1, LED screen price
The price may be an important factor influencing to buy LED large screens. Although everyone understands the principle of low price is not a good product, it will unconsciously move closer to lower prices when choosing LED screen manufacturers. The huge difference resulted in customers ignoring quality. However, in actual use, it may be that low price is low quality.
2, LED screen production
Many customers who have purchased LED full color screens have just placed an order and they can't wait to get the goods right away. This kind of mood we understand very much, but the LED large screen is a customized product, and after the completion of production, it needs at least 48 hours to test and test. The LED screen increases 24 hours to reach the 72-hour non-stop detection test on the national standard. Short delivery time usually has two problems: First, there is no adequate testing, the use of failure rate in the later period is certainly relatively high; but some manufacturers do not have enough of the same batch of spot, it may be to take orders Use a different batch of product. In this case, the display will have a significant color difference, which will greatly affect the LED display.
3, LED screen parameters
The general customer purchases the LED screen screen will choose several factories to carry on the appraisal, then decides the LED big screen supplier. The two important items in the competition are price and technical parameters. In the case of similar prices, the technical parameters become the winners and losers. Many customers think that the higher the number of parameters, the better the display quality. Is that actually not the case? We give a simple example, is also the indoor P4 full-color display, on the screen brightness value this one. Some manufacturers will write 2000cd/m2, and some manufacturers will write 1200cd/m2. Is that 2000 better than 1200? The answer is not necessarily, because the indoor LED screen brightness requirements are not high, generally between 800-1500 on it. If the brightness is too high, it will be dazzled and affect the viewing. From the perspective of the service life, the brightness is too high and it is easy to advance the life of the display. So a reasonable use of the brightness is the positive solution, not the higher the brightness the better. The same model, but also some parameters, such as LED lamp brand / packaging, scanning methods, power refresh rate, power consumption, gray, etc., parameters of different prices will not be the same.
4, LED screen pixel pitch
In the large LED screen sales process, I often come across the customer that the same model of the display, why your price is so much more expensive than others. I'm so devastated because I quote my customers according to the company channel price. I found out by chance that the so-called products of the same model were actually different. We use the P4 LED screen as an example. In general, we say that the P4 LED large screen refers to a pixel pitch of 4.0 mm, but there is a 4.81 mm pitch on the market, which is the p4.81 led screen
. Customers who do not understand externally, Some salespeople use coverless methods and claim to be P4 full-color LED displays. In this way, the gap in the price of quotations will be more obvious, and many customers who do not understand will think that they have bought a good product at a low price.
