In small indoor venues, such as community activity center activities, the audience is close to the display, it is recommended to choose P2.6 pixel pitch display. For example, for community cultural performances, the P2.6 display has many pixels per square meter, which can clearly present the actors’ makeup and expressions, and the text display is also sharp and clear, so that the audience can feel the delicate images from a close distance. Large outdoor plaza activities, such as city celebrations, the audience is widely distributed, viewing distance, P3.9 pixel pitch is more appropriate, in the long-distance viewing, to ensure that the overall picture can be recognized, the cost is also lower, the audience in the back rows can also see the main content of the display.

P2.6 is extremely delicate, with natural color transition and rich details. In art exhibition activities, when displaying high-resolution artwork pictures, it can accurately restore the brushstrokes and color levels of the work, so that the audience can feel the charm of art.P3.9 is relatively rough, with details lost, but the overall visual effect is still good when displaying in a large area. In large-scale sports events, used to display the athletes’ game screen, although individual pixel points are obvious, but the audience can see the athletes’ movements, the overall situation of the field, to meet the basic viewing needs.

The smaller the pixel pitch, the higher the cost of the display. Smaller pixel pitches require more sophisticated technology, more pixels, and a complex production process. When the budget of a public event is limited, it is important to clarify the core requirements of the event in terms of picture clarity. If the activity does not require high detail display, such as large-scale outdoor public welfare activities, you can choose a larger pixel pitch display to reduce costs, while optimizing the display size, choose the appropriate leasing program, etc., to meet the needs of the activity display within the budget. For example, the originally planned P2.6 screen can be replaced by a P3.9 screen to reduce the cost per square meter, and then the display area can be reasonably adjusted to ensure that the budget is controllable and the display effect is acceptable.

Conventional flat screens are widely used and suitable for most public activity scenarios. In shopping mall promotional activities, it is used to display product information, promotional prices, etc. It is easy to install and can be spliced into a large display area to provide audiences with clear and regular information display. In large-scale conference activities, it is used as a background screen to display the conference theme, speech content, etc., and can stably present relevant images. Shaped screens shine in the pursuit of creativity and unique visual effects in the activities. At the opening ceremony of an art exhibition, curved display screens surround the video related to the art work, which can create an immersive art atmosphere and allow the audience to better feel the charm of art. In theme park activities, circular, triangular and other shaped screens are used to create a characteristic landscape, such as setting up a circular display at the entrance of the park to play a welcome video, attracting the attention of tourists and adding fun and uniqueness to the activity.

Between performances or during breaks in activities, use a clean, soft rag to gently wipe the dust on the surface of the display to maintain the screen’s translucency and avoid the accumulation of dust affecting the display effect. Check the environment around the display to ensure that there are no debris blocking the vents to ensure good heat dissipation from the display to prevent failure due to overheating. Pay close attention to the operation status of the display, if you find abnormalities in the screen (such as flickering, color change, color blocking, etc.), record the phenomenon in a timely manner and contact the technicians to deal with it. Regularly check the power connection and signal lines to ensure that the connection is firm and not loose or detached to prevent the display from malfunctioning due to line problems. If the display supports automatic brightness adjustment function, check whether the automatic adjustment function works normally according to the change of light at the activity site, and if it is abnormal, adjust the brightness manually to ensure that the picture is clear and visible.
