LCD mainly includes TFT, UFB, TFD, STN and other types of LCD. The structure of LCD is to place liquid crystal in two parallel glasses. There are many vertical and horizontal small wires between the two glasses. The direction of rod crystal molecules is controlled by power on, and the light is refracted to produce a picture.   High brightness, The higher the brightness value of the array LCD, the brighter the picture will be without blurring. Advanced display can display clearer and higher brightness product features. We rely on polarization filters and light itself. With the practice of natural light in all corners of the world, a series of liquid crystal filters must be parallel.   The higher the contrast, the more colorful and saturated the color will be, and the higher the plane will be. On the contrary, the color change is low, the color display is poor, the image will be flattened, and the color change value is different, even higher. Compared with CRT imager, LCD dot matrix LCD display has the advantages of zero radiation, low power consumption, small heat dissipation, small volume, accurate image recovery and high character visualization.   The view of “big view” simply means that the view in front of the screen can be seen the larger the sight distance, the easier it will be; As long as the viewer changes the viewing position slightly, the picture may become blurred.

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

LCD splicing screens are divided into optical seamless LCD splicing screens and electronic seamless LCD splicing screens. The realization principle of the optical seamless LCD splicing screen is to install a special optical glass panel body on an ordinary 3.5mm panel, and realize the principle of line-of-sight refraction through the glass, so that the originally split screen can be seen in an image through the optical glass , The seams with black edges are completely invisible, and the display effect of the picture is real. The realization principle of seamless LCD splicing screen electronics is that by installing a special electronic bar on each panel unit, the electronic bar emits light equivalent to LED, and the light is emitted by two electronic bars between the seams, which can be displayed on the display. Achieve seamless seams. The seamless LCD panel joining technology has reached an unprecedented level, realizing the arrival of the era of true seamless joining technology. The seamless LCD panel joining technology is used in the high-end display field. It can be said that the visual impact it brings is also unprecedented. The seam adopts full-screen active LED electronic pixel compensation display, and the optical lens and optical refraction principle are seamless. The pixel pitch of LED electronic pixel correction is 1.5mm or less. The electronic pixel compensation LED adopts SMD label technology and does not use large particle lamp-like display. After LED electronic pixel correction, the edge of the condenser lens with high transmittance is added to
