1. Please don’t just look at the price when purchasing LED screens
Price may be one of the most important factors affecting the purchase of LED screens. Although everyone understands the principle that you get what you pay for, you still unconsciously favor low-priced LED screens when choosing led screen products. There is a very large price difference between LED screens produced by different brands and different technologies. But most customers will ignore the quality of the LED screen itself due to the huge price difference when purchasing LED screens.
Taking flexible LED screen as an example, high-end flexible video wall often deters many customers because of its high price. But from a long-term perspective, the comprehensive average cost of use of high-end flexible led screens will be lower than that of low-end flexible led screens. Because in addition to the initial purchase cost, the low-end flexible led screen will incur more maintenance and replacement costs during use.
2. The "same model" of the LED screen does not necessarily mean the "same product"
In the process of manufacturing and selling LED screens, we often encounter customers asking such questions—why do the same LED screen models have huge price differences? As the leading manufacturer in the field of LED screen, GalaxyAV has performed very well in both quality and cost control. It’s hard to imagine that, as the source factory, the price of the same LED screen model is much higher than that of other LED screens sold by us.
In fact, this is because the customer does not know the product model and technical parameters of the LED screen. Take the P4LED display as an example. Generally speaking, the P4LED large screen we refer to refers to a pixel pitch of 4.0mm. However, there are displays with a pitch of 4.81mm, which is p4.81, on the market. Some LED screen suppliers may claim that this is a P4 full-color LED display. In this way, the quotation gap will be more obvious, and many customers who don’t understand think that they have bought a good product at a low price.
3.The higher the value of the LED screen's technical specifications isn't the better
Generally, when purchasing LED screens, customers will choose several manufacturers for evaluation, and then decide the supplier of LED screens. The two most important items in the competition are price and technical parameters. In the case of similar prices, the technical parameters become the winner. Many customers think that the higher the parameter value, the better the quality of the display. Is that actually the case?
Let’s take a simple example, it is also an indoor P4 full-color display screen, in terms of the brightness value of the display screen. Some manufacturers will write 2000cd/square meter, and some manufacturers will write 1200cd/square meter. So is 2000 better than 1200? The answer is not necessarily!
Because the brightness requirements of indoor LED screens are not high, generally between 800-1500 is enough. If the brightness is too high, it will be dazzling and affect viewing. In terms of service life, if the brightness is too high, it will easily overdraw the life of the display screen in advance.
Therefore, the rational use of brightness is the positive solution, not that the higher the brightness, the better. For the same model, some parameters are required, such as LED lamp brand/package, scanning method, power refresh rate, power consumption, gray scale, etc. The price will vary with different parameters.
4. The LED screen display does not want to be tested for a long time
Many customers who buy LED screen want the goods to be delivered as soon as they place an order. We understand this feeling very well, but LED screens are usually customized products, which require at least 48 hours of inspection and testing after production is completed.
When the LED display screen is exported, an additional 24-hour uninterrupted inspection test will be added. Why? Because the delivery time is too short, it will generally lead to two problems: one is that there is no sufficient testing and testing, and the failure rate in later use will definitely be relatively high; The order uses a product from a different batch. In this case, the display screen will have obvious color difference, which will greatly affect the display effect of the LED large screen.
The above are the 4 common mistakes when purchasing LED screens, I hope you can avoid them when purchasing LED screens.
