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.

With the rapid development of digital information technology, the overall technology in the urban transportation field has also been effectively improved, and information modernization and intelligence have gradually been realized, and “smart transportation” has gradually been realized from the concept. Based on the background of smart transportation, how to realize the smart display of traffic information is the key. In-depth analysis of the application and advantages of digital signage in smart transportation, aviation, subway and rail transit. Airport flight display application With the rapid development of social processes, the digital construction of urban airports not only assumes the responsibility of aviation infrastructure, but also becomes the central hub of regional economic integration and urban internationalization. The year-on-year increase in passenger throughput and the continuous improvement of airport service quality have placed stringent requirements on real-time information updates and display equipment at the airport. Actually used in airport scenarios, digital signage can be used as a large aviation display screen to realize the intelligent display of information. On the one hand, after being equipped with the CMS messaging system, it can realize the unified scheduling and control of the information released by multiple terminal devices, present flight and boarding gate information in real time, realize flight information guidance, meet the needs of passenger flow information identification, and can also follow up in time. Check-in status of each flight to enhance the passenger’s flight experience; in addition, information such as flight number, remaining flight tickets, city weather and other information can also

Resolution Resolution is a very important performance indicator. It refers to the number of points that can be displayed horizontally and vertically on the screen (lines and planes on the screen are composed of points). The higher the resolution, the more information can be included in the same screen. 480×800 resolution and 320×240 resolution are perfect display. Because there is little difference between the two, but the maximum resolution is not necessarily the most appropriate resolution. If 480×8000 LCD is used in 320×240 LCD, the display content will be smaller.   Visual area of LCD It refers to the part of the display area that can be used to display the image in practical application. The full size is actually the size of its frame and PCB board, and the part that can be used to display images does not reach this size at all, because the frame takes up some space. Generally speaking, the area of 4-inch 480×800 LCD is 51.84×86.4mm, and that of 3.5-inch 320×240 LCD is 70.08×52.56mm. But for LCD, the size of area is basically the size of the visible area, and the space occupied by the frame is relatively small. The 4-inch 480×800 LCD has a display area of 51.84 * 86.4mm.So choose LCD screen, choose suitable for your own equipment.   Reaction speed The unit of time used to measure reaction speed is millisecond (ms), which is the time required for a pixel to go from light to dark and from dark to light.
