The vehicle mounted screen with full-color screen is generally refitted with vehicles such as Iveco, which takes into account several problems. The first is the shockproof of the screen body, because considering the influence of road and other factors, shockproof is very necessary; The second is the problem of heat dissipation. Poor heat dissipation results in the decline of the service life of the components of the display screen and the high temperature in the compartment, so the heat dissipation scheme is particularly important, considering the problems such as power supply and air circulation.
Vehicle LED electronic screen has the novel characteristics of real-time, flexibility, mobility and large capacity. For users who have some “visual fatigue” for the stationary LED electronic screen, this new way has been favored by users.
Taking the bus mounted LED electronic screen as an example, it can provide passengers with important ride information and route information. In addition, the advertising effect is prominent. A city’s bus is still one of the main means of transportation for public travel, with millions of passengers every day. The number of people it carries is huge. The “free time” on the bus for more than ten minutes is leisurely and boring. If there is a flowing and colorful display screen in front of it to broadcast news, sports and entertainment, weather, advertising information, etc., this active “duck feeding” reading media in front of it can attract the attention of passengers to the greatest extent and achieve good advertising effect.
For taxis, the on-board screen is not harmful to the car. They can also get advertising revenue. Why not? In addition, the GPS led on-board screen can use GPS to locate the vehicle and return the position, which is conducive to the taxi management center or bus dispatching center to grasp the vehicle position at any time, realize real-time dispatching, and achieve the purpose of reducing the no-load rate and alleviating traffic congestion.
For government official vehicles and police vehicles, the LED on-board screen has a large storage capacity. It can appeal daily advertising, news, policies and regulations, public convenience information (such as weather forecast), urban culture, traffic and other information to the public through the display screen. Its public welfare is particularly prominent. It is the mouthpiece of the government and the window of urban civilization. In addition, in case of a criminal case, GPS can timely notify 110 of the driving position, route and other information of the alarm vehicle. At the same time, the LED vehicle screen outside the window will flash “I’m robbed, please call the police” and other contents, which can effectively control and crack down on crimes.
