How to solve the dark spots on the LCD screen?

With the advancement of science and technology, mobile mobile phone LCD screen displays are becoming more and more popular. However, the inherent and unavoidable shortcomings of LCD screens have also been emphasized. When it comes to black spots on LCD screens, many people may not understand. Today, I will teach you how to look at black spots, I hope it can help you. What are dark spots on an LCD screen? In fact, dark spots are more concealed than bright spots and bad spots, but their impact on use is far greater than bad spots. Sometimes on some displays, there are patches that are not very large. The small black class is as big as a soybean, and the large class may be as big as a thumb. Different from the bright and dark spots, the dark color system has only a slightly darker local color, which is not easy to find from the front, but easy to find only from the side. The main reason for the formation of dark spots is that the external force has been squeezed for a long time. We think that it is likely to be during the transportation process, and the black spots appear due to improper handling. LCD screens with black dots are often hard to find from the front and are more noticeable from the sides (like testing viewing angles). We recommend that when buying an LCD screen, not only check the dead pixels of the screen, but also look at the screen surface from multiple angles, and set the screen to white. If there is a dark spot problem at this time, the dark spot will disappear.
