The era is developing, and technology is advancing. As the current mainstream commercial display screen, Samsung LCD splicing screen has a very high usage rate and can be used in various fields of various industries. As the LCD splicing screen industry is getting bigger and bigger, it has changed from production to consumption. The quality of products sold in the market is different. If you don't pay attention, you may fall into the pit.

First, pay attention to the size of the size

Some rogue LCD splicing screen manufacturers may be able to size their hands. When you sign the contract payment, you are told that it is a 47-inch splicing screen, but when you deliver it, take a 46-inch LCD splicing screen to pretend. If the user doesn't pay attention, then they can get away with it. If found, they may also die and say that this is 47 inches. Therefore, if you are not sure how many dimensions, you can measure the length of the diagonal of the LCD panel. The length of the diagonal is the size of the product.

Second, we must pay attention to whether it is refurbished

Some unscrupulous splicing screen manufacturers will renovate old machines and sell them, or use second-hand panels to modify them. This kind of refurbished machine may not have problems when it is first used, but it will affect the use after a long time.

Don't fall into these "pits" when buying Samsung LCD splicing screens.

Third, whether to low charge

The brightness of the panel of the LCD splicing screen has two options, namely low brightness and high brightness. The highlight is 700cd/m2, and the low-brightness is 450cd/m2. It is difficult for laymen to see the difference from the naked eye, but the cost is nearly doubled. Therefore, the user should pay attention to the purchase, do not be smashed by the low-brightness splicing screen of the non-defective households with high-brightness splicing screen. 

Fourth, whether to improve the perfect after-sales service

Some merchants don't care after the sale of goods. If the customer goes to the factory after purchasing, they will change the normal state and do not provide after-sales service. If there is any problem with the LCD splicing equipment, it will cause the customer a headache.

Therefore, it is recommended that you must purchase the guaranteed LCD splicing screen manufacturers, which is not only a transaction, but also the protection of the entire project and subsequent use.
