With the development of LCD advertising players, the market demand for wall-mounted LCD advertising players has gradually increased, and a large number of manufacturers of various sizes have emerged with uneven products. Especially affected by the epidemic, many factories have closed down, and major display equipment manufacturers have fought price wars. Therefore, the profits of enterprises are getting lower and lower, so consumers are very worried about the quality of the products. Here are three aspects that you should pay attention to when buying a display screen.
1. LED lights
The LCD tube can be said to be the top priority of the entire wall-mounted LCD advertising machine display device. Its cost can generally account for half or even 75 percent of the total cost of the entire device. Therefore, you must understand the brand, size, and related products of the die before buying.
2. LED display steel structure
The proportion of the display structure in the overall cost is basically the same as the driving method. But in the configuration of the equipment, there is also a wealth of knowledge. Some devices on the equipment are simple cases, and some are waterproof cases. For different types, the difference lies in whether they have a back door and the thickness of the box.
In terms of structure, should I choose modular splicing or the light board directly fixed on the box board? Modular disassembly is more convenient, so maintenance is also more convenient. If the box is directly fixed, the maintenance of the later equipment will be more difficult.
3. After-sales service
Due to the troublesome disassembly of the wall-mounted LCD advertising machine and the relatively high technical content, the after-sales link is more important than ordinary electrical equipment. Therefore, when buying a wall-mounted LCD advertising player, we must fully understand the manufacturer's scale, brand, reputation, etc., and pay more attention to after-sales service.
