Especially after the emergence of bankruptcy in recent years, various manufacturers have fought price wars and corporate profit margins. Almost reached the bottom. Therefore, consumers are very worried about the quality of the products. How to choose manufacturers to become consumers. With the increase in demand for LED display
s, a large number of manufacturers have emerged, and manufacturers of various sizes have mixed good and bad, especially in recent years. After the wave of bankruptcy appeared, various manufacturers fought a price war, and corporate profit margins almost reached the bottom. Therefore, consumers are very worried about the quality of the products, and how to choose manufacturers has become a headache for consumers. 一.LED lamp For the , the liquid crystal tube can be said to be the most important in the entire display device, and its cost can generally account for half or even 70% of the cost. Therefore, usually the construction party will write the configuration of the display equipment and so on when listing the plan to the customer. This generally includes the brand, size, and related products of the die. In fact, at this point, the first mystery appeared. For the die on the market today, although the function may not be much worse. But the prices of different brands are quite different. Therefore, when understanding the solution, it doesn't matter whether it depends on the configuration. We also need to carefully study the brand characteristics. 二. steel structure For the display structure, its proportion in the overall cost is basically the same as the driving method. But there is also a wealth of knowledge in the configuration of the equipment. For example, on the cabinet of the device, some devices are simple cabinets, and some seem to be simple but waterproof cabinets. For different types, their differences are mainly reflected in whether they have a back door and the thickness of the box. In addition, in the choice of structure, there are many differences in whether to choose modular splicing or the light board directly fixed on the box board. If it is a modular type, because it is more convenient to disassemble, so it is more convenient to repair. If the box plate is directly fixed, it is obviously difficult to maintain the equipment. 三. After-sales service After-sales service for equipment is often the most overlooked place. Maybe a lot of users will think that they just need to adjust the things, and they also need to look at the after-sales service. And sometimes when I listen to the dealers flicking, what our equipment is good, after-sales is basically a display of clouds. Therefore, I regard the after-sales service as a decoration. But in fact, due to the troublesome LED disassembly and high technical content, it is obviously more important than ordinary electrical equipment in the after-sales link. Nowadays, many manufacturers promise to have long after-sales service, but most of them send equipment faulty parts back to the manufacturer for repair. We will not comment on the scale of these manufacturers, but for users, if we can find the defective points and deal with it ourselves, Do we still need to send it back? What is such a promise, not cheating? Therefore, when buying an , it is no longer the same as buying a TV in the past. Simply check the price and pay. We should not only compare the scale, brand, reputation, etc. of manufacturers, but also pay special attention to after-sales service. In this way, the follow-up use and maintenance of the product will avoid many unnecessary troubles. Full-color Two-color Indoor Outdoor Transparent LED glass screen
