Classification and installation of LED wall display products

According to relevant agencies, with the rapid development of various emerging markets, outdoor media, advertising, outdoor display, special-shaped screens and other market performance, in which LED display is becoming a hot product in the industry. With the continuous progress and updating of LED technology, the civil market of LED wall display? is gradually valued by many LED enterprises. Advertising forms are flexible. In recent years, LED wall display has been widely valued and developed rapidly, which is closely related to its own advantages. LED development prospects are extremely broad, at present, LED is moving towards higher brightness, higher weather resistance, higher luminous density, higher luminous uniformity, the direction of development. But for users, the size model is still relatively concerned, in addition to the need to consider the installation environment, price and so on. Next, we will introduce some knowledge of the display screen. 1.Classification of display panels The LED wall display? is divided into indoor LED display, semi-outdoor LED display screen and outdoor LED display screen according to the use environment. First, the common outdoor LED display models include: P8, P10, P12, P16, P20, P25, P31.25, etc. The indoor screen area is generally from less than 1 square meter to more than 10 square meters, the point density is higher, in the non-sunlight direct or lighting environment use, viewing distance in a few meters away, the screen does not have sealing waterproof ability. Semi-outdoor screen between the outdoor and indoor, with high luminous brightness, can be used in non-direct sunlight outdoor, the screen has a certain seal, generally under the eaves or in the window. 2.Synchronous control card and asynchronous control card. Synchronization means that the LED wall display works in the same way as a computer monitor. It maps the image on the computer monitor in real time at least 30 fields/seconds update rate point by point. It usually has multi-gray color display ability, and can achieve multimedia advertising effect. Asynchronous mode refers to the LED display screen with the ability of storage and automatic playback, edited text and grayless pictures on the PC through serial port or other network interface into the LED screen, and then automatically played off-line by the LED screen, generally no multi-grayscale display capability, mainly used to display text information, can be multi-screen networking. . 3.Installation mode of display screen Embedded: Steel structure is installed on the wall, and then steel structure is used as support to embed outdoor full-color LED display screen, mainly installed in the building's external wall. Wall hanging type: generally do a force point on the wall, the outdoor LED full-color screen hanging on the wall, using the wall as a fixed support. Column type: Because there is no wall around or available support points, column type installation of steel structure requires higher requirements, is the most common installation method. For example, outdoor advertising screens beside the expressway mostly adopt this way. Step type: mainly in the steps of the vertical installation of dual-color LED display screen or full-color screen, high-density LED screen, observation distance generally 3 meters away will have a better effect. Hoisting type: mainly uses the designed steel structure to hang the outdoor LED screen body on the structure. Usually in the stage, outdoor without wall support in the case of the use of temporary outdoor LED display, hoisting mode has obvious advantages.
