In recent years, people's demand for LED electronic display screens has gradually increased, and users often need to purchase a large number of LED electronic display screen products. However, with the increase in the demand for LED display screens, a large number of LED display screen manufacturers have emerged, and various large and small manufacturers are intertwined with each other. Especially after the "bankruptcy" in recent years, LED display manufacturing Businesses fought a price war, and corporate profit margins almost fell to the bottom. In this way, consumers are very worried about the quality of the product. How to choose an LED display has become a headache for consumers. The following will introduce several aspects that should be paid attention to when buying a display.

1. LED lamp beads
For LED display screens, LED lamp beads can be said to be the top priority of the entire display device, and its cost can generally account for even about half of the cost of about 70 percent . Therefore, when the customer orders the listing plan, it will also be written in the display device configuration, and so on. There is a common brand of packaged LED lamp beads, size, resolution, lifespan, and related products. Here, the first mystery appears. For the current LED display on the market, although the function may be far. But the prices of different brands are quite different. Therefore, the understanding of the program depends not only on the configuration. We have to carefully consider the characteristics of which brand.
Two, led display steel structure
For the display structure, its proportion in the total cost is basically the same as that of the driver. However, there is also a wealth of knowledge in equipment configuration. For example, in terms of equipment, some equipment is a simple chassis, and some seem to be a simple but waterproof chassis. For different types, the main difference lies in whether there is a back door and the thickness of the box.
In addition, there are many differences in the choice of structure, the choice of module splicing, and whether the light board is directly fixed on the box board. If it is a modular type, because it is more convenient to disassemble, it is more convenient to maintain. If the box plate is directly fixed, it is obviously necessary to increase the difficulty of equipment maintenance.

Three, after-sales service
For after-sales service LED display equipment, it is often the most overlooked place for us. Maybe many users may think that you have something to adjust, and what services are they looking at? Sometimes we listen to dealers fooling around, we are very good equipment, furniture, etc. are basic sales, so we treat ourselves as decoration sales.
But in fact, due to the troublesome disassembly and high technical content of LEDs, the after-sales link is obviously more important than ordinary electrical appliances. Nowadays, many manufacturers promise after-sales service time, but most manufacturers will send equipment faulty parts back to the manufacturer for repair. We do not comment on the scale of these manufacturers, but for users, if we can find the bad places and deal with them ourselves, will we send them back?

Therefore, when buying a led screen, it is no longer the same as buying a TV. Just know the price and pay the bill. We must not only compare the scale, brand, reputation, etc. of manufacturers, but also pay special attention to after-sales service. The follow-up use and maintenance of the product will avoid many unnecessary troubles.
