1. The main screen, the main screen is the display screen in the center of the stage.
Most of the time, the main screen is shaped like an approximate square or rectangle.
And because of the importance of the content it displays, the pixel density of the main screen is relatively high.
At present, the display specifications for the main screen are mainly P4, P5 and P6.
2, the secondary screen, the secondary screen is used for the display on both sides of the main screen.
Its main function is to set off the main screen, so the content it displays is relatively abstract.
Therefore, the models used are relatively large. The commonly used specifications are: P7.
62, P8, P10, P12 and P16 models.
3. Video expansion screen, which is mainly used in relatively large occasions, such as large-scale concerts, song and dance concerts, etc.
In these occasions, because the venue is relatively large, there are many places where the performance characters and effects on the stage cannot be clearly seen, so one or two large screens are set on the side of these venues.
Its content is generally a live broadcast of the stage. Now the commonly used specifications are similar to the main screen. The three specifications of P4, P5 and P6 are used more.
