LED advertising screens occupy a dominant position in the advertising field. According to the different needs of each project, for example, there will be different trade-offs in the selection of pixels, resolution, price, playback content, display
life, and front or rear maintenance. What are the suggestions for purchasing outdoor LED advertising screens? Of course, the load-bearing capacity of the installation site, the brightness around the installation site, the viewing distance and viewing angle of the audience, the weather and climatic conditions of the installation site, whether it is rainproof, whether it is ventilated or not, etc. must also be considered. So how to purchase LED advertising screens? Here are some suggestions for photoelectricity. 1. The need to display content. The ratio of length to width is determined by the actual content of the picture. The video screen is generally 4:3 or the nearest 4:3, and the ideal ratio is 16:9. 2. Confirmation of visual distance and viewing angle. In order to ensure long-distance visibility under strong light conditions, ultra-high-brightness light-emitting diodes must be selected. 3. The design of appearance and shape. At present, it has been possible to customize the LED advertising screen according to the design and shape of the building, which is to apply the touch display technology to the extreme to achieve an extremely perfect visual effect. 4. It is necessary to pay attention to the fire safety of the installation site and the energy-saving standards of the project; of course, when selecting, brand factors, LED advertising screen quality, product after-sales service and other aspects are important factors that need to be considered. The display screen is installed outdoors, often in the sun, rain, wind and sun, and the working environment is harsh. If electronic equipment gets wet or severely damp, it can cause short circuit or even fire, cause malfunction or even fire, and cause damage. Therefore, the requirement on the structure is to take into account the weather conditions and be able to protect against wind, rain, and lightning. 5. Requirements of the installation environment. Use industrial-grade integrated circuit chips with a working temperature between -40°C and 80°C to prevent the display from starting up due to low temperatures in winter. Install ventilation equipment to cool down so that the internal temperature of the screen is between -10°C and 40°C. An axial fan is installed on the top of the back of the screen, which can discharge heat when the temperature is too high. 6. Cost control. The power consumption of LED advertising screens is an element that must be considered.
