Jak si vybrat při nákupu LED displeje?

V posledních letech, poptávka lidí po LED elektronických displejích se postupně zvyšuje, and users often need to buy a large number of LED electronic display screen products. nicméně, with the growth of demand for LED display screen, 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 wave” v posledních letech, LED display screen manufacturers have fought a price war, and the profit margin of enterprises has almost fallen to the bottom. Takto, consumers are very worried about the quality of products. How to select LED display screen has become a headache for consumers. The following will introduce several aspects to pay attention to when buying display screen.
1、 LED bulb
For LED display screen, LED lamp beads can be said that the priority of the top of the whole display device can generally account for half of even about 70% of the cost. Proto, the listing scheme of customer orders will also be written in the display device configuration, a tak dále. There is a universal packaging LED bulb brand, velikost, řešení, životnost, and related products. Tady, the first mystery appears. For the LED display on the current market, although the function may be far away. But the prices of different brands are very different. Proto, the understanding of the program depends not only on the configuration. Which brand, we should carefully consider its characteristics.
II. LED display steel structure
For the display structure, its proportion in the total cost is basically the same as that of the driver. nicméně, he also has rich knowledge of equipment configuration. Například, in terms of equipment, some equipment are simple chassis, and some seem to be simple but waterproof chassis. For different types, the difference mainly lies in whether there is a back door and the thickness of the box.
Kromě toho, there are many differences in the selection of structure, module splicing and whether the lamp board is directly fixed on the box board. If it is modular, it is more convenient to disassemble, so it is more convenient to maintain. If the box plate is directly fixed, it is obviously necessary to improve the maintenance difficulty of the equipment.
3、 After sales service
LED display equipment for after-sales service is often the most easily overlooked place. Maybe many users may think you have something to tune and what services to see. Sometimes we listen to the dealer’s deception that we are good equipment, furniture and so on, which is the basic sales, so we regard ourselves as a decoration sales.
But in fact, due to the troublesome disassembly and high technical content of LED, it is obviously more important than ordinary electrical appliances in the after-sales link. Dnes, mnoho výrobců slibuje poprodejní servis, ale většina výrobců vrátí vadné součásti zařízení výrobci k údržbě. Nekomentujeme rozsah těchto výrobců, ale pro uživatele, pokud dokážeme najít špatná místa a sami se s nimi vypořádat, pošleme je zpět??
Proto, při nákupu LED obrazovky, už to není totéž jako nákup TV. Stačí znát cenu a zaplatit účet. Neměli bychom porovnávat pouze měřítko, značka a pověst výrobců, but also pay special attention to after-sales service. The subsequent use and maintenance of the product will avoid many unnecessary troubles.
