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.

Whether it is the local post office, the district court, or the national library— public sectors, owing to their very nature of serving the public, have to rely on communication. However, in reality, public offices and institutions are hardly the places where you will find yourself receiving information effortlessly. The public sector has a thing or two to learn from the trailblazing world of the private sector. The merit of communication comes first on that list. While corporate offices are furnished with large digital signage displays at every nook and corner (disseminating information clearly and concisely), most public sector offices are still lagging as far as digitization is concerned. This post points out some of the umpteen ways in which digital signage can benefit the public sector. 5 most significant benefits of using digital signage in the public sector 1. Way-finding made easier   Public offices are busy places. Large public sector buildings are nothing short of a befuddling maze. Often it’s hard to figure out who is a staff and who is a visitor. Haven’t we all had the experience of running from cubicle-to-cubicle in search of a person of interest? Or simply running in circles throughout the building looking for a department? These are petty inconveniences that can be easily avoided. A simple digital signage solution can solve so many problems at one go. Authorities can deploy wayfinding digital signage at various locations like: Entry and exit gates Parking lots Lobby and reception Staircase and elevator zones Corridors leading to

Pixel is a kind of unit. Generally speaking, it is invisible to the naked eye. How can we see the pixels of LCD? That is, if the image of LCD is magnified several times, many small square dots will be found. These small square dots are actually the so-called pixels.   The LCD splicing unit of LCD is a full-color screen, and red, green and blue are the primary colors of colors. Because LCD has many colors to realize, it needs to combine the red, green and blue lights to form pixels.   The pixel of LCD is a unit used to calculate the digital impression. Just like the photo taken, the digital impression also has continuous tone. If you enlarge the impression several times, you will find that these continuous colors are actually composed of many small dots near the color.   In addition, the pixels of LCD include real pixel display and virtual pixel display. The two technologies are different. The virtual display adopts virtual pixel technology, that is, LCD multiplexing technology. The same LCD light-emitting tube can be combined 4 times with adjacent LCD light-emitting tubes (down, down, left, and right combinations). Generally speaking, the pixel is a unit. The pixels of the current LCD display are 1920 * 1080, and the pixels of the Department display can be as high as 3840 * 2160. The higher the pixel, and more clearer the picture will be.
