Large Outdoor Video Screens are the development trend in the advertising industry in the 21st century. It is an indoor and outdoor advertising display device with audio and video functions. It is also an internationally leading high-tech product. The appearance of this kind of equipment is novel and unique, and its area can be adjusted at will. It can not only play audio and video advertising programs but also can be equipped with fixed lightbox advertising spaces on all sides. It is mainly used for outdoor advertising, stations, squares, shopping malls, etc. Large Outdoor Video Screens is generally tens of square meters to hundreds of square meters or even larger, with high brightness and large viewing angle, they can work in the sun, and has certain wind, rain, and waterproof functions. Due to the great changes in the brightness of the surrounding environment during the day and night, the effect of energy saving and emission reduction can be achieved by automatically adjusting the brightness of the outdoor LED display.
With the continuous development of the urban construction process, Large Outdoor Video Screens are being used more and more as a new media advertising carrier. The Large Outdoor Tv Screens can indeed bring a certain improvement to the image of the city, and the form of advertising is also flexible and diverse. However, there are still some matters needing attention during the use of outdoor LED displays: Outdoor LED displays generally have a large area, so they are still very heavy. To choose the best Large Outdoor Video Screens, the first thing to pay attention to is the structural design. The installation structure should take into account: wind resistance, earthquake resistance, bearing, and other main factors; secondly, the shape, structure, and exterior decoration design of the screen should be coordinated with the attached building or environment; moreover, consider the local environmental factors, such as Air humidity, air salinity content (coastal cities), etc. How to choose a Large Outdoor Video Screens and what should you pay attention to when installing?
Reasonably plan the area and installation location of the display screen
According to the viewing distance and viewing angle, the surrounding environment, and the requirements of the display content, the display area and location should be planned reasonably. Instead of blindly pursuing a large area and a prominent location.
Multi-level grayscale correction technology improves color softness.
LED display products use more gray levels to make the color look softer and the transition is natural.
Adopt a brightness adjustment system that can be automatically adjusted by the system
The brightness of the environment at different times and locations varies greatly. If the playback brightness of the display is greater than the ambient brightness, it will cause people’s eyes to be uncomfortable, especially when the brightness difference between day and night is relatively large, causing light pollution, and the automatic brightness adjustment system can Automatically convert the broadcast brightness suitable for the environment to avoid light pollution.
Lightning protection measures for the installation of buildings and screens
In order to prevent the display from being attacked by strong electromagnetic waves caused by lightning, the Large Outdoor Video Screens and the outer packaging protective layer must be grounded, and the resistance of the grounded line should be less than 3 ohms so that the current caused by thunder can be timely From the ground line.
Waterproof, dustproof, and moisture-proof measures for the entire screen
A seamless connection should be made at the junction of the box body and the box body, as well as the junction of the screen body and the installation object under force, so as to avoid water leakage and dampness. There must be good drainage and ventilation measures inside the Large Outdoor Video Screens, and if there is water accumulation inside, it can be dealt with in time.
About the choice of circuit chip
In the northern region, the temperature in winter can generally reach ten degrees below zero. When selecting circuit chips, it is necessary to choose industrial-grade chips with a working temperature of minus 40 degrees Celsius, which means 80 degrees Celsius. The Large Outdoor Tv Screens cannot start.
Ventilation measures should be taken inside the screen
When the Large Outdoor Video Screens are energized and working, they will generate a certain amount of heat. If this heat is not discharged and accumulated to a certain extent, it will cause the internal environment temperature to be too high, which will affect the operation of the integrated circuit, and can cause burnout in serious cases. The display does not work. Therefore, it is necessary to do a good job of ventilation and heat dissipation measures inside the screen, and the temperature of the internal environment is maintained between minus 10 degrees and 40 degrees.
The choice of highlight wick
Choosing a high-luminance LED tube allows us to display good results under direct sunlight, and it can also enhance the contrast with the surrounding environment so that the audience of the picture is wider.
