Today, outdoor LED displays dominate the advertising landscape. Depending on the needs of each project, there will be different trade-offs, such as the choice of pixels, resolution, price, broadcast content, display life and front or rear maintenance. Of course, we also need to 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 or not to protect against rain, whether or not to ventilate the heat and other external conditions. So how to purchase LED display? The following is a bit of advice from
LED Controller.1, the need to display content. Aspect ratio, graphic diploma according to the reality of the content to determine the video screen, generally 4:3 or close to 4:3, the ideal ratio is 16:9.
2, the visual distance, the confirmation of the angle of view. In order to ensure that the light in the case of strong long-distance visualization, must choose ultra-high brightness light-emitting diodes.
3, the appearance of the shape of the design, has been able to do according to the design of the building and the shape of the customized LED display, such as the 2008 Olympic Games and the Spring Festival Gala, is the LED display technology is applied to the extreme, in order to achieve extremely perfect visual effect.
4, need to pay attention to the installation site fire safety, etc., the project's energy-saving standards, etc.; of course, in the choice, brand factors, LED screen quality, product after-sales service and other aspects, are important factors to consider. Display screen installed in the outdoors, often sun and rain, wind and sun, harsh working environment. Electronic equipment is wet or serious moisture will cause short circuit or even fire, triggering failure or even fire, resulting in loss. So in the structure of the structure above the requirements is the need to take into account the weather conditions, can do to windproof, rainproof, lightning.
5, the requirements of the installation environment. Selection of industrial-grade IC chips with operating temperatures between -40℃ and 80℃ to prevent the display from not starting in winter when the temperature is too low. Installation of ventilation equipment to cool down the internal temperature of the screen body between -10 ℃ and 40 ℃. Install an axial fan above the back of the screen body to discharge heat when the temperature is too high.
6, cost control. The power consumption of the display screen is an element that must be considered.
