Polarizer is an important part of LCD screen. With the emergence of special full matching technology, polarizers are more and more widely used in LCD. What role does polarizer play in LCD?   Polarizer is widely used in LCD industry, and LCD needs to use polarizer. Polarizer and liquid crystal play an important role in development. In the production process, two pieces of ordinary tempered glass are printed on the circuit, and then glued together and folded. Then the liquid crystal is injected into the middle of the two sides of the glass, and the polarizer is pasted on the top and bottom of the glass.   The upper and lower glass should be pasted with polarizer, but pay attention to the direction. If the lower polarizer filters the x-direction light, the upper polarizer can only filter the y-direction light. If the upper polarizer filters out the light in the Y direction and the lower polarizer filters out the light in the X direction, the user can see nothing. Although the LCD works normally, the polarizer is not visible to the naked eye. Now the LCD color screen is generally only on the film, not on the film, the product technology innovation.   People who have studied physics should know what polarized light is. The imaging of LCD must rely on polarized light. All liquid crystals have two polarizers close to the liquid crystal glass to form a liquid crystal sheet with a total thickness of about 1 mm.

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. Digital signage display terminal-self-service terminal display-digital signage display Secondly, in terms of content, networked digital signage self-service terminals can achieve online real-time updates, which gives advertisers absolute control over advertising content, and can push advertising information regularly and at fixed points according to the behavioral habits of target audiences. Enhance the accuracy of advertising. At the same time, advertisers can also carry out flexible packaging of advertising based on current affairs hotspots, breaking the rigidity of traditional advertising pushes, and avoiding audience resentment and affecting corporate brands. In the course of business operations, specialized marketing strategies are indispensable. However, a study found that only 20% of traditional marketing campaigns can impress consumers. This also

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
