1. What is the Truck LED display?

The truck display is a kind of LED display screen. The difference from the ordinary display screen is that it is installed on the car and is movable.

Let us define it. It is a flexible device that uses a dedicated power supply, control card, and unit board to display text, pictures, animation, and video on and off the dot matrix. It also can be divided into fixed LED display and rental LED display.

As an independent led display system, its requirements for stability, anti-interference, anti-vibration, waterproof and dustproof are higher than ordinary led display screens installed in fixed places.

The perfect performance of the truck LED display comes from the support of multiple technologies.

For instance, LED technology, GSM/GPRS technology, low-temperature technology, anti-static technology, anti-interference technology, vehicle electronic technology, etc.

With the blessing of these technologies, truck LED display screens can display information on mobile cars and become the new favorite of the advertising industry.

6. Special Requirements for Truck LED Display

It is different from the ordinary LED display installed in a fixed place. The reason is that the truck LED display is installed on the vehicle and the vehicle often moves. The following requirements are required for the installation. 

(1). The truck is prone to generate static electricity during operation, especially in autumn when the static high voltage can reach thousands of volts. Without good anti-static measures, it is easy to damage IC and LED lights.

(2). The power supply on the vehicle is supplied by the battery. The vehicle will generate high pulse voltage when starting, braking and stopping. If the power supply system is not good, the display screen will be burned.

(3). LED attenuation characteristics: LED brightness is attenuated, with a 10-70% attenuation rate in a year. The brightness of half-year with poor quality is reduced by half, making it impossible to see the display clearly.

(4). In the north, trucks are usually placed outdoors. The temperature may reach – 40 ℃ in winter and 60 ℃ in summer, which requires the power supply and display components to work at a wide temperature.

(5). Appropriate brightness. If the LED display is not bright enough, it will not be visible in the daytime, and the significance of installing the display is lost; If it is too bright, it will affect driving.

(6). The truck is always moving, and the stability and reliability of electronic products are highly required.7. Common features of the truck LED display screen include appearance and size. Led display with 2 or 3 sides.

7. Configuration of Mobile LED Advertising Truck

The truck LED display is an associated product after the rise of the LED display industry. This product combines a van with a large LED display for mobile advertising.

Generally speaking, mobile LED advertising vehicles are composed of four main parts: vehicle chassis, LED display screen, power supply system, and operating system.

7.1 Vehicle chassis

The design of the chassis has fully considered the effect of temperature on the working of the truck LED display.

The bottom of the car is a U-thumb floor. The interior uses high-temperature resistant aluminum, and the middle interlayer uses polyurethane foam insulation.

When the outdoor temperature is too high or too low, it will not affect the operation of the equipment inside the vehicle.

7.2 LED display screen

Different models of advertising vehicles use dissimilar LED display models. However, they also have some similarities. For example, the full-color LED screen is popular for mobile LED advertising trucks.

They are full of three-dimensional sense and have a strong visual impact. This unique way of advertising is more likely to attract people’s attention.

The LED display system and the body installation use multiple rubber blocks with good vibration damping performance to buffer the vibration caused by the body movement.

The exterior of the display is protected by plexiglass, which has waterproof protection and unique anti-ultraviolet performance for the LED display system.

Moreover, a double-sided LED screen is a good choice for a truck. The LED screen cabinet is light in weight, stylish and simple in appearance, ultra-thin and beautiful, and supports a split-screen multi-screen display.

The double-sided screen developed by UNIT LED adopts front maintenance, a simple structure, and convenient installation.
