Nowadays, outdoor high brightness LCD screens dominate the advertising field. According to the different requirements of each project, such as the choice of pixels, resolution, price, playback content, display lifespan, and front or rear maintenance, there will be different trade-offs. Of course, it is also necessary to consider the load-bearing capacity of the installation site, the brightness around the installation site, the viewing distance and angle of the audience, the weather and climate conditions of the installation site, whether it is rainproof, whether it is ventilated and dissipated, and other external conditions. So how to purchase outdoor high brightness LCD screens? Here is a suggestion from the editor.
1. The need to display content. The aspect ratio is determined based on the actual content of the image and text. For video screens, it is generally 4:3 or the nearest 4:3, and the ideal ratio is 16:9.
2. Confirmation of visual distance and perspective. In order to ensure long-distance visibility in strong light conditions, ultra-high brightness light-emitting diodes must be selected.
3. The design of the appearance and shape has now been able to customize LED display screens according to the design and shape of the building. For example, in the 2008 Olympics and Spring Festival Gala, LED display technology was applied to the extreme to achieve extremely perfect visual effects.
4. Attention should be paid to the fire safety of the installation site, as well as the energy-saving standards of the project; Of course, when choosing, brand factors, LED screen quality, product after-sales service, and other aspects are all important factors to consider. The display screen is installed outdoors, often exposed to sunlight and rain, wind and sun, and the working environment is harsh. Electronic devices that are wet or severely damp can cause short circuits or even fires, leading to malfunctions or even fires, causing losses. So the requirement in terms of structural design is to consider the weather conditions and be able to prevent wind, rain, and lightning.
5. Requirements for installation environment. Select industrial grade integrated circuit chips with a working temperature between -40 ℃ and 80 ℃ to prevent the display screen from being unable to start due to low temperatures in winter. Install ventilation equipment to cool down and keep the internal temperature of the screen between -10 ℃ and 40 ℃. An axial flow fan is installed above the back of the screen, which can discharge heat when the temperature is too high.
6. Cost control. The power consumption of the display screen is a necessary factor to consider.
