What do you need to pay attention to when purchasing lcd display screens? Focus on the following three points:

I. LCD display screens backlight.

For lcd display screens, LCD backlight lamp can be said to be the most important thing in the whole display equipment, its cost can generally account for half or even 70% of the cost. Therefore, usually, when the construction party makes a proposal list for the customer, it will also write down the configuration of the device, and so on. This generally includes the backlight tube core brand, size, as well as related products and so on. Ah, in fact, at this point, the first mystery appeared. For the backlight wick on the market today, although the function may not be much worse. But different brand prices are very different. Therefore, when understanding the scenario, regardless of the configuration. We also have to ponder over the characteristics of the brand.

II. Steel structure of LCD display screens.

For the display structure, its proportion in the whole cost is basically the same as the driving mode. However, in the configuration of equipment, there is also a wealth of knowledge. For example, on the box of equipment, some devices are simple chassis, some seem simple but waterproof chassis. 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, whether to choose modular splicing, or the lamp board is directly fixed on the box board, there are many differences. If it is a module, because the disassembly is more convenient, so the maintenance is more convenient, and directly fix the box board, it is obvious to improve the maintenance difficulty of the equipment.

III. After-sales service of LCD display screens.

As for the after-sales service of lcd display equipment, it is often the place that we are most likely to ignore. Perhaps many users will think that things have been adjusted, but also look at what after-sales service ah. And sometimes listen to dealers cheat, what our equipment is good, after-sales is basically decorated. Therefore, they also put themselves after the sale as a decoration. But in fact, because the lcd disassembly trouble, and the technical content is high, so in the after-sale link, obviously more important than the ordinary electrical equipment. Today, many manufacturers promise to have how long after the sale, but most of the equipment failure is sent back to the manufacturer for repair, we do not comment on the size of these manufacturers, but for users. If we can find the bad points ourselves and deal with them ourselves, do we have to send them back? If such a promise is not a trick, what is it?

So, when purchasing a lcd display screen, it is no longer the same as buying a TV in the past, simply knowing the price and paying the bill. We should not only compare the size of manufacturers, brands, word-of-mouth, etc., but also pay special attention to after-sales service. In this way, the subsequent use and maintenance of the product will avoid a lot of unnecessary trouble.
