How to choose outdoor LED displays according to the environment

nowadays, outdoor LED displays occupy a leading position in the advertising field. There will be different tradeoffs according to the different needs of each project, such as different choices of pixels, resolution, price, playback content, display life, and front or rear maintenance. Of course, we should also consider 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 climate conditions of the installation site, whether it is rainproof, whether it is ventilated and cooled, and other external conditions. So 3. The sliding surface between the inlaid steel plate and the lining plate and the dovetail groove surface on the lining plate should be kept clean. How to purchase LED display? Here are some suggestions

1. The need for display content. The length width ratio depends on the actual content. The video screen is generally 4:3 or 4:3 nearby, and the ideal ratio is 16:9

2. Confirmation of visual distance and angle of view. In order to ensure long-distance visibility in strong light, ultra-high brightness LED must be selected

3. At present, the design of appearance and shape has been able to customize the LED display screen according to the design and shape of the building. For example, the 2008 Olympic Games and the Spring Festival Gala have applied the LED display technology to the extreme to achieve an extremely perfect visual effect

4. Attention should be paid to the fire safety of the installation site and the energy-saving standards of the project; Of course, brand factors, LED screen quality, product after-sales service and other aspects need to be considered when choosing. The display is installed outdoors, often exposed to the sun and rain, wind and sun, and the working environment is poor. The sub equipment of the electronic universal testing machine controlled by the electric microcomputer will be wetted or seriously damped, which will cause short circuit or even fire, cause failure or even fire, and cause losses. Therefore, the requirement of the structure is to take into account the weather conditions and be able to prevent wind, rain and lightning

5. Requirements for installation environment. Industrial grade integrated circuit chips with working temperature between -40 ℃ - 80 ℃ are selected to prevent the display screen from starting due to low temperature in winter. The sewage can be transferred to the sewage treatment plant by installing ventilation equipment to cool down, so that the internal temperature of the screen is 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 must be considered
