Advantages of LCD

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.

The difference between the projector’s LCD and DLP seamless splicing screen projection

When consumers choose a projector, they usually encounter two keywords, LCD and DLP. What are the LCD and DLP seamless splicing screen projection technologies of the projector and what are the differences? Please see below. With the development of science and technology, projection technology has gradually entered the era of digital technology from LCD technology. Nowadays, the application of projectors has spread to all walks of life and came into being. There are also various brands in the technology market. For users who want to choose products, there is only one old saying: choose only the right ones, not the ones Dear. What are the LCD and DLP seamless splicing screen projection technologies of the projector? Here, I only use my personal understanding of the two major technologies of the projector to make some comments on the adaptation direction of the two types of technical products, so as to facilitate the majority of users to consider when choosing products. Liquid crystal technology is famous for its bright colors, lifelike images, high number of colors, and rich image levels. Suitable for multimedia, film and television, advertising and other industries. The disadvantage is that the light source loss is large, and the background color of the screen cannot achieve a pure white effect; after long-term use, the LCD panel is easy to age, the color is easy to attenuate, the imaging unit is larger, and the heat dissipation requirements are high. Therefore, the appearance of the LCD technology projector is general The

Four core components of digital signage

Digital signage is a problem that we have discussed more recently, because digital signage is a relatively advanced identification product, and it is also a direction of the development of the sign industry. Therefore, it is reasonable for us to analyze the key points of digital signage. On the one hand, we can strengthen the promotion of digital signage. On the other hand, we can also help the promotion of digital signage. Today, our theme is an integral part of digital signage, that is to say, digital signage. What are the parts? We sorted out the following 4 parts: 1. The shell part, the shell is the part that we can see intuitively. The digital signage is not just a screen. The digital signage we see in reality will be in various shapes, looks very beautiful and generous, not alone The display, therefore, this shell has a very important decorative role. Although it does not help digital signage in terms of function, digital signage is also part of the entire identification system. Of course, the outline of the shape needs to be consistent with the overall style, so , This shell is essentially as important as other identification products. 2. Display, what we have a deeper understanding of digital signage at this stage should be the touch screen. This is a typical display device and an important link between digital signage and users. 3. The operating system and the shell have no soul, and the display itself has no soul.
