LCD mainly consists of LCD black-and-white screen and TFT color screen. The following mainly introduces the relationship between the manufacturing difficulty and size of LCD black-and-white screen: According to expert statistics, the size and process difficulty of LCD segment code screen have such a rule: the larger the size, the more complex the manufacturing process. The main reasons are as follows:   The larger the size of LCD, the more difficult it is for staff to operate.   The larger the size of LCD is, the higher the requirement of equipment grade is.   The larger the size of LCD, the higher the defect rate of the product.   The larger the size of LCD, the more bad things will appear, such as darkening.

With the progress of science and technology, LCD is more and more popular. However, the inherent and inevitable shortcomings of LCD have also been paid attention to. When it comes to LCD black spots, many people may not understand. Today, I will teach you how to look at black spots. I hope it can help you.   What is the dark spot of LCD? In fact, dark spot is more hidden than bright spot and bad spot, but its influence on use is far greater than bad spot. Sometimes on some screens, there will be some patches that are not very big. The black small class is as big as the soybean, and the big class may be as big as the thumb. Different from the bright and dark spots, the dark color system is only partially dark, which is not easy to find from the front, but only from the side.   The main reason for the formation of dark spots is that the external force has been squeezed for long time. We think that it is probably due to improper handling in the transportation process. LCD screens with black dots are usually hard to find on the front and more obvious on the side (just like the test perspective).We suggest that when you buy LCD, you should not only look at the bad points of the screen, but also look at the surface of the screen from multiple angles, and set the screen to white. If you find

The small-pitch LED display has the characteristics of high refresh, high grayscale, high brightness utilization, no image retention, low power consumption, and low EMI. It is not reflective for indoor applications, and the display contrast is as high as 5000:1; it is lightweight and ultra-thin, High precision, small space for transportation and use, quiet and efficient heat dissipation. Small-pitch LED display products have a wider color gamut space and faster response speed than ordinary large LED screens, and can realize seamless splicing and modular maintenance of any size. The whole picture played is uniform in color, high-definition lifelike, no abnormal display such as sweat spots and bright lines that are common on ordinary screens, and the picture switching is soft and does not flicker, and the picture quality is very delicate, which is close to the playback effect of a TV. The contrast ratio of 5000:1 can show excellent blackness when the screen is black, and it is the best among similar products. The biggest competitiveness of indoor high-density and small-pitch LED displays lies in the complete seamlessness of the large screen and the natural and true display colors. At the same time, in terms of post-maintenance, the LED large screen already has a mature point-by-point calibration technology. The large screen used for more than one or two years can be used to perform a one-time calibration of the entire screen. The operation process is simple and the effect is very good. When using a small-pitch LED display, pay attention
