Generally speaking, P5 monochrome LED display is used to guide the flow of people at the entrances and exits of stations, docks, large markets, and elevator entrances. It has the advantages of clear font, low price and cluster control. For banks, shopping malls and other occasions to display corporate image, advertising and other applications, the price is required to be low, and the P3.75 dual-color display is used. It is required to display picture and video effects and use P5 full-color display.

For occasions with a large hall area, P5 dual-color LED display is used, and the display effect is required, and P1O full-color LED display is used. For the function definition of service windows in business halls such as banks, post offices, and electric power, the sticker method was used in the past, which was very inflexible. Now using the P5 single and dual color display, the service function of the window can be changed at any time.

The outdoor LED display has higher quality requirements because of the harsh use environment, and there are many factors to be considered. Because of its high brightness, full color, and all-weather work, it has its irreplaceable advantages, but the price is relatively high compared to single and dual-color LED displays. From an application point of view, a product that meets user needs has a reason to exist. The dual-primary color display screen occupies a large market with its low price, maturity and stability when the display text and color requirements are not high, and there is no blue color. The size and viewing distance of the outdoor LED full-color display screen play a decisive role in the price. The farther the distance, the larger the selected model, the larger the pixel, and the higher the brightness.
