How to solve the dark spot on LCD screen?

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

2021 Display panel industry Research Report

With the support of policies and funds, China has become the largest LCD panel supply market in the world. According to the statistics of China Business Industry Research Institute, China’s panel production capacity accounted for about 29% in 2016, and it is expected that China’s panel production capacity will account for 56% by 2022.   LCD panel is promoted by policy, technology and capital The LCD panel industry is capital intensive, labor-intensive, and driven by market demand. The development of panel enterprises needs policy support, technology development and capital investment. LCD panel cycle weakened, the profitability of manufacturers increased significantly Due to the two-year construction period and one-year capacity climbing period, the past LCD panel showed a strong periodicity. As the industry enters the late stage of maturity, the willingness of manufacturers to build new production capacity is greatly reduced. According to our supply and demand model, the compound growth rate of LCD production capacity in the next three years will be 3.1%; The compound growth rate of LCD demand side is about 6.5%, the supply and demand pattern of the industry will be improved, the periodicity will be significantly weakened, the panel price will be maintained in a reasonable range, and the profitability of LCD panel manufacturers will be greatly improved. LCD panel has entered the era of China, and the panel “two heroes” take off The display panel industry is a key industry supported by the state, and the state has issued a number of policies to support

Market development of LCD splicing screen

In recent years, there have been more and more LCD splicing screen manufacturers, and competition in the large-screen splicing market has gradually become fierce. With the continuous breakthroughs in the three mainstream splicing product technologies such as LCD LCD splicing, DLP rear projection splicing, and PDP plasma splicing, LCD splicing There are more and more types of screens, and more and more diversified sizes, and there are more options for users to choose from. However, LCD splicing screens also have two sides, so the current large-screen splicing market is facing a complex situation such as a large number of convergent products and chaotic price wars. Especially with the rapid development and wide application of the LCD splicing industry, some people in the industry have suggested that the large-screen splicing industry may face a reshuffle. So where is the future of large-screen splicing? From the overall splicing market, analyze the technical aspects and industry applications of the three large-screen products, LCD LCD splicing screen, DLP rear projection splicing screen, and PDP plasma splicing screen. LCD splicing screens are the first choice. Since Samsung launched 46-inch ultra-narrow-edge splicing products in 2009, the LCD splicing market has shown a sustained high growth trend. The large LCD splicing screen has the advantages of high definition, high brightness, high color saturation, flexible splicing display combination, environmental protection and health, long life span, and low maintenance cost. At present, the largest LCD splicing unit on the market can be as large as 65 inches, and is
