Kako odabrati prilikom kupnje LED zaslona?

Posljednjih godina, potražnja ljudi za LED zaslonom elektroničkog zaslona postupno raste, and users often need to buy a large number of LED electronic display screen products. Međutim, 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” posljednjih godina, LED display screen manufacturers have fought a price war, and the profit margin of enterprises has almost fallen to the bottom. Na ovaj način, 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. Stoga, the listing scheme of customer orders will also be written in the display device configuration, and so on. There is a universal packaging LED bulb brand, veličina, razlučivost, vijek trajanja, and related products. Ovdje, 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. Stoga, 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. Međutim, he also has rich knowledge of equipment configuration. Na primjer, 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.
U Dodatku, 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
Oprema LED zaslona za postprodajne usluge često je mjesto koje se najlakše zanemaruje. Možda će mnogi korisnici pomisliti da imate nešto prilagoditi i koje usluge vidjeti. Ponekad slušamo trgovčevu obmanu da smo dobra oprema, namještaj i tako dalje, što je osnovna prodaja, pa se smatramo rasprodajom ukrasa.
Ali zapravo, zbog problematičnog rastavljanja i visokog tehničkog sadržaja LED dioda, očito je važniji od običnih električnih aparata u postprodajnoj poveznici. Ovih dana, many manufacturers promise after-sales service time, but most manufacturers will return the equipment fault parts to the manufacturer for maintenance. We don’t comment on the scale of these manufacturers, but for users, if we can find bad places and deal with them ourselves, will we send them back?
Stoga, when buying LED screen, it is no longer the same as buying TV. Just know the price and pay the bill. We should not only compare the scale, brand and reputation of manufacturers, but also pay special attention to after-sales service. The subsequent use and maintenance of the product will avoid many unnecessary troubles.
