An outdoor LED display or mobile led display trailer and a light-duty trailer are combined to create a mobile LED screen trailer, or mobile LED billboard trailer, which makes it easier to move an LED display. It is frequently used for outdoor live broadcasts, live music performances, advertising and marketing, sporting events, festivals, outdoor television, and other uses. The trailer chassis, LED display & multimedia system, power supply system, hydraulic lifting, and rotating system, and control cabinet box make up the framework of the LED screen trailer.
According to the weight of the entire trailer load, mobile LED screen trailers typically come in single-axle or double-axle sizes. Varying nations, such as those in Europe and North America, have different regulations and standards for trailers. It is crucial to construct the trailer following your country’s transportation laws.
The LED trailer multimedia system consists of an LED display, a control card, speakers, a video processor, a power amplifier, and other components. The trailer-mounted LED screen is available in indoor and outdoor configurations.
Trailer LED screens are classified by pixel pitch as P3, P4, P5, P6, P8, and P10 trailer LED screens. In general, smaller pixel-pitch LED screens are more expensive than larger ones. Other elements influencing trailer LED screen quality include DIP or SMD, IC brand, power supply, control card, and so on. These characteristics will have a significant impact on the trailer LED screen’s brightness, refresh rate, contrast, life, and battery consumption.
To achieve audio output, the mobile LED screen trailer is also equipped with two or four outdoor weatherproof speakers and the corresponding power amplifier. A video processor or multi-functional box will also be installed to enable video signal display conversion and output trail LED to the screen.
There are several different ways to power the portable LED trailer. The LED screen trailer can use a 110V or 220V power supply depending on the voltage norms of various nations. The onboard generator can also be used to power the LED screen trailer.
It should be noted that the generator must be silent and provide the necessary power for all of the trailer’s electrical components, including the hydraulic system motor, speakers, and amplifiers mounted on the trailer.
You may also use batteries and solar electricity to run a single-color LED display. This is advantageous since solar energy and battery power cannot adequately power LED billboard trailers because the majority of outdoor LED displays mounted on trailers have a high power.
To display videos, animations, photos, and words on the trailer LED display, there are synchronous control and asynchronous control options. These two control systems accept hardware and software choices from the LED screen and trailer.
The synchronization system synchronizes and displays the content on the trailer LED screen in real-time with the content on the control computer monitor. Because synchronized control lacks storage memory, it needs a PC or laptop.
The asynchronous display allows you to submit edited content in advance to the control card of the trailer LED screen using your computer, laptop, phone, tablet, SD card, or USB flash drive. The control card, which has memory storage, will display the edited content in order once it has received the content.
