How to Check the Bad Spot of Industrial Display

The core component of the industrial display is the LCD screen, which accounts for seven to eight percent of the total production cost of the product, showing its importance. When we buy industrial displays, the most concerned about the quality of the LCD screen, a quality LCD screen can make the industrial display play a colorful picture, customer visual experience will be better.

Bad spot is one of the quality problems affecting the visual experience of industrial display, including bright spot and dark spot. So when we buy industrial displays, we should avoid choosing products with these two problems. The following is how to share the method of checking the bad points of industrial displays.

Under normal circumstances, the quality of the LCD screen of the industrial display is not visible. No matter what function of the industrial display, the quality of the LCD screen is not around the topic, its cost accounted for the machine cost of 70, 80 percent, do not want people to pay attention to difficult. Consumer is more cautious about the bad point problem of LCD screen, usually before buying consumers will carefully observe whether there are bright spots and dark spots on the screen, this is a very good habit. Choose liquid crystal screen must move the screen perfect green and whole blue, a lot of consumers like to look for dark spot when white screen, look for window when black screen, although this kind of practice is correct, but look for it so very expends effort however and vision wants very good ability to ok. Here I give you a tip: in the full green screen when looking for dark spots, full blue screen when looking for bright spots, once there is a bright spot or dark spots very easy to see. If there are no bright spots or dark spots, almost all consumers will put the issue aside, which is a very wrong approach, for the following two reasons.

First, the bright spot and dark spot on the LCD panel will not only be produced in the manufacturing process, but also may appear in the use process. And once the bad point is impossible to repair, only to replace the entire display to solve the problem.

Ii. “Uncertain factors” in the transportation process. When we buy, the industrial display inspection did not find a problem, but does not mean that you get the product without a problem, that is why? Because the product in the process of delivery there are uncertain factors, such as logistics personnel in the loading process, no light take light, transportation process of the product collision extrusion will cause damage to the LCD screen of the industrial display, it is easy to produce the so-called bad point.

For the LCD screen bad point problem, there is still no relevant laws and regulations, and the industry has an unwritten provision, LCD panel less than 3 (including 3) bright spot, bad point, the LCD is still a normal product, consumers can not be replaced by this reason. In this case, there is no provision to back it up, even if the problem arises. Businesses do have the right to reject “unreasonable” demands from consumers.

For consumers, want to buy products without defects, so bad before pay best point problem and businesses to reach an agreement, after all this time is that consumers have the initiative, and in the presence of their will to choose good product packaging, loading until transport to the designated place, do not give any chink in the wall.
