A mobile LED screen trailer, or mobile roadshows, is made by combining an outdoor LED display or mobile LED display trailer with a light-duty trailer, making it simpler to transport an LED display. It is frequently used for outdoor live broadcasts, live music performances, marketing and advertising, festivals, athletic events, and other functions. The framework of the LED screen trailer is made up of the trailer chassis, the LED display and multimedia system, the power supply system, the hydraulic lifting and rotating system, and the control cabinet box.
Mobile LED screen trailers normally come in single-axle or double-axle sizes depending on the weight of the total trailer load. Different countries, including those in Europe and North America, have various rules and requirements for trailers. It is essential to build the trailer by the transportation legislation of your nation.
An LED display, a control card, speakers, a video processor, a power amplifier, and other parts make up the LED trailer multimedia system. Both indoor and outdoor setups are offered for the trailer-mounted LED screen.
P3, P4, P5, P6, P8, and P10 trailer LED displays are the different pixel pitch categories for trailer LED screens. The cost of lower pixel-pitch LED panels is typically higher than that of bigger ones. DIP or SMD, IC brand, power supply, control card, and other factors might also affect the quality of a trailer’s LED display. The brightness, refresh rate, contrast, longevity, and energy usage of the trailer LED screen will all be significantly influenced by these factors.
The movable LED screen trailer is additionally outfitted with two to four outdoor weatherproof speakers and the matching power amplifier to achieve audio output. The installation of a video processor or multi-functional box will also allow for the conversion of video signals and their output to the trailer LED display screen.
The movable LED trailer can be powered in a variety of ways. Depending on the voltage standards of different countries, the LED screen trailer can use a 110V or 220V power source. The LED screen trailer can also be powered by the onboard generator.
It should be noted that the generator needs to be silent and supply all of the trailer’s electrical parts, including the hydraulic system motor, speakers, and amplifiers mounted on the trailer, with the necessary power.
One-color LED displays can also be powered by batteries and solar energy. This is helpful because the majority of outdoor LED displays mounted on trailers have high power consumption, making solar energy and battery power insufficient to sufficiently power LED billboard trailers.
There are synchronous control and asynchronous control options available for displaying films, animations, images, and text on the trailer LED display. The LED screen and trailer can choose the hardware and software these two control systems use.
The synchronization system synchronizes and displays the information on the control computer monitor and the LED screen of the trailer in real-time. Synchronized control requires a PC or laptop because it lacks storage memory.
Using your computer, laptop, phone, tablet, SD card, or USB flash drive, you can upload edited content in advance to the control card of the trailer LED screen thanks to asynchronous displays. Once the content has been received, the control card’s memory store will display the edited contents in chronological sequence.
