An advertising truck works by combining a mobile vehicle with display and audio systems. First, its truck chassis provides mobility, allowing it to move to target areas like streets or events. Then, the LED screen (with adjustable brightness) shows ads—controlled by a system supporting videos/images/text. A high-power sound system enhances engagement by playing audio. It operates in -20℃ to 60℃, with waterproof/dustproof features. Drivers navigate to high-traffic spots, making the truck a flexible, eye-catching tool to deliver ads to broad audiences.
