LED display used in the background of the stage is called the stage LED display. The large LED display is the perfect combination of technology and media. The intuitive and outstanding representative is that the background we have seen on the stage of the Spring Festival Gala in the past two years is the applied LED display The screen, rich scenes, large screen size, and gorgeous content performance can make people feel immersive in the scene.
To create a more shocking effect, the choice of screen is very important.
To subdivide the stage LED display, it is mainly divided into three parts:
1. The main screen, the main screen is the display in the center of the stage. Most of the time, the main screen shape is approximately square or rectangular. And because of the importance of the content it displays, the pixel density of the main screen is relatively high. The display specifications currently used for the main screen are mainly P2.5, P3, P3.91, P4, P4.81, P5.
Second, the secondary screen, the secondary screen is the display screen used 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 it uses are relatively large. The commonly used specifications are: P3.91, P4, P4.81, P5, P6, P7.62, P8, P10, P16 and other models.
3.Video expansion screen, which is mainly used in relatively large occasions, such as large-scale concerts, singing and dancing concerts, etc. In these occasions, because the venue is relatively large, there are many places where it is impossible to clearly see the characters and effects on the stage, so one or two large screens are installed on the sides of these venues. The content is generally live broadcast on the stage. Nowadays, the commonly used specifications are similar to the main screen. LED displays of P3, P3.91, P4, P4.81, and P5 are more commonly used.
Due to the special use environment of LED stage display, in addition to product quality and specifications, there are several points to note:
1. Control equipment: It is mainly composed of control system card, splicing video processor, video matrix, mixer and power supply system, etc. It is compatible with multiple signal source inputs, such as AV, S-Video, DVI, VGA , YPBPr, HDMI, SDI, DP, etc., can play video, graphic and image programs at will, and broadcast all kinds of information in real-time, synchronized, and clear information dissemination;
2. The adjustment of the color and brightness of the screen should be convenient and quick, and the screen can quickly show delicate and lifelike color performance according to the needs;
