According to the application field, LED display can be roughly divided into outdoor LED display and indoor LED display. Relatively speaking, LED displays used outdoors are much stricter than indoor LED displays in terms of materials and production processes, mainly because the outdoor environmental conditions are much harsher than indoors, and they are uncontrollable or uncontrollable. There are also more determining factors, which makes the LED display used in the outdoor need to have many characteristics, so that the LED display can run stably and for a long time.
So, what characteristics do the installation of outdoor LED display need to have?
In the outdoor environment, rain and dust need to be considered. For this reason, the LED display needs to have a high protection level, and the waterproof and dustproof level should be at least IP65 or above. Only in this way can rain and dust be prevented from entering the interior of the display. Affect the normal operation of the display. It would be even better if the protection level of the LED display module could be IP68. After all, the IP68 level can completely prevent water or dust from entering the display module. Even if it is placed in water, the module can work normally.
Of course, as far as LED displays are concerned, we believe that even displays for indoor applications should be flame-retardant and fire-resistant. However, relatively speaking, LED displays for outdoor applications have higher requirements for flame retardant and fire protection. This is mainly because the outdoor environment is generally relatively high in temperature. For example, in the Middle East countries, the outdoor ambient temperature is relatively high, especially when the LED display When the screen is placed on the roof or in an outdoor area without any shelter, the LED display needs to withstand higher temperatures. At this time, it is more suitable to choose a die-casting aluminum module than a plastic module, because the die-casting aluminum material is not only flame retardant and fireproof, but also has a better heat dissipation effect. Die-cast aluminum will not deform due to excessive outdoor temperature, and will not spontaneously ignite, therefore, most of the aluminum module LED displays we see are used outdoors, and the aluminum modules used in indoor applications will be much less.
Many people may only consider the price when choosing an LED display, but do not consider the power consumption. In fact, power consumption is also very important, especially for outdoor LED displays. Generally speaking, LED displays installed outdoors are relatively large in size, because the outdoor space is large enough, and the larger the LED display, the wider the coverage and the more audiences it can reach. Generally speaking, the larger the size of the LED display screen, the higher the power consumption, but there are still many ways to reduce the power consumption of the display screen, such as the common cathode power supply technology, which can improve the power utilization rate of the display screen and reduce the power consumption, its power consumption reduction effect can reach 30% to 75%, which can greatly reduce the expenditure on electricity bills, and can save a lot of electricity bills in one year. On the other hand, the LED display using common cathode technology improves the utilization rate of electric energy, so the loss of electric energy will naturally be reduced, and the heat will naturally be reduced during the operation of the display screen, this aspect can also extend the life of the display. Therefore, when we choose LED displays installed outdoors, energy saving and low power consumption should also be taken into account.
Of course, in addition to the above points, LED displays installed outdoors have many other features, such as convenient front and rear maintenance, project budget, etc., but only those that can meet the above points can be regarded as a good outdoor LED display.
