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

Networked digital signage can not only upload content through the network, but also centrally control the equipment through the network. This not only solves the problem of content flexibility, but also allows users to independently update the playback content at any time, improve the quality of digital signage content, and bring many benefits to merchants or enterprises from a long-term perspective. First of all, from the appearance. The types of digital signage display terminals are very diverse. In addition to general products with large screens and high-definition features, there are special products such as special-shaped splicing, transparent display, and naked eye 3D to meet the creative application needs of specific users and maximize advertising. The main advertising information can be noticed by the target group. This is a major prerequisite for ensuring the efficiency of transmission.

In 2020, as the epidemic has stimulated people’s demand for work, study, entertainment and other applications at home, the display industry has achieved rapid development, and the upstream chip of the supply chain is also booming. Affected by the global chip shortage, display driver chips are facing price increases. According to data, the total demand for display driver chips is expected to grow to 8.4 billion in 2021. In the display driver chip market, Taiwanese design companies occupy a dominant position in the LCD field, accounting for nearly 80% of the market in 2020. Heria and ILITEK ranked first and second respectively. Due to the sudden attack of the epidemic in 2019, all factories were halted urgently, resulting in a shortage of ILITEK’s chip inventory. In addition, due to the global shortage of COVID-19 vaccines, only about 11% of Taiwan’s population has been vaccinated, which has caused difficulties for factories to resume work, and has exacerbated the problem of imbalance between supply and demand in the market. Chip prices will continue to rise in the future.
