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.

With the popularization of the construction of national smart cities and safe cities, LCD splicing screens, as the best terminal display equipment, are favored by various industries and are perfectly integrated into our lives; as we all know, the LCD splicing industry is a sunrise industry with broad development. The prospects and entry barriers are extremely low. Therefore, the LCD splicing market has attracted an influx of many manufacturers, and the actual products of manufacturers are uneven. The viewing angle of the LCD splicing screen can reach 178 degrees, while the ordinary LCD can only see the 178-degree blank space. This is a very important criterion for distinguishing LCD splicing screens and LCD monitors. There is also the difference between the input signals of the two. The splicing screen is mainly the input video signal. In order to meet the interface requirements of different front-end devices, the splicing screen interface will be much richer than the display, including BNC, VGA, RGB, HDMI, DVI, S A variety of interfaces such as terminals meet the input requirements of different signals, while the monitor mainly inputs VGA signals, and the interfaces are mainly VGA, S-terminal, etc., which cannot meet the signal input requirements of various monitoring equipment. What is the difference between an LCD splicing screen and an LCD monitor, be sure to read it clearly when buying The driving scheme of LCD splicing screen is different, that is, the display motherboard scheme is different. Since the LCD display usually takes no more

Everyone is very familiar with LCD TVs, but many people don’t understand digital signage products. In fact, when we go to a hotel or shopping mall, we often see this product in the lobby, which often displays the advertising content of the hotel or shopping mall.

In addition to the hotels we are talking about, many retail industries have also begun to use digital signage products. For example, the fast food restaurants we often go to have used light boxes behind the ordering counters to display their dishes. Now many stores have also upgraded to digital signage products. In simple terms, digital signage is actually a numerical display system used in the commercial field. 1. Digital signage is usually equipped with a system Here is the system, in fact, this is the biggest difference between digital signage and liquid crystal display. We all know that the LCD monitor itself is only responsible for the function of screen output. The most important role of digital signage is actually the system behind it. Different from ordinary intelligent LCD, the digital signage system has the function of remote management. Users can design the display content by themselves, or download the template
