Since the concept of smart city was proposed, it has received strong support from local governments, and the state has invested a large amount of funds to ensure the effective progress of various work.In the process of smart city construction, the concept of "smart" has been deeply rooted in the hearts of people, which has imperceptibly led to the development of many industrial markets, among which the most noteworthy is the huge impact on the transportation industry.According to statistics, in the first half of 2018, China‘s urban intelligent transportation market reached 8 billion yuan, up 2.6 percent year on year.
Traditional transportation industry into a new concept of "smart", give person find everything new and fresh, more modern feeling, also let the led display industry of high-tech industry in the 8 billion market saw unlimited business opportunities, attract many led companies start for intelligent transportation market, developed a variety of suitable for segmentation in the field of intelligence traffic led display products.Among them, led on-board screen is known as "small screen with great power", which is applied to buses, taxis or all kinds of cars specially customized for this purpose...Vehicle, by virtue of excellent mobility publicity effect, has been valued and favored by the market.

Walking LED vehicle screen excellent mobile publicity effect
Led car screens are not visible, but they can be seen everywhere.Different from the conventional door head screen and fixed LED screen, LED on-board screen is suitable for buses, taxis, advertising vehicles and other mobile vehicles. It is an independent LED on-board display system with the rapid development of LED screen.Due to the uniqueness of the application place of LED on-board screen, it also means that it has higher requirements on product stability, anti-interference, shockproof, dustproof and other aspects, requiring strict control by the manufacturer in all aspects.
In the traditional consciousness of many people, the LED on-board screen is the LED single-color bar screen on the top or rear window of a taxi, which is used to scroll text messages and advertising messages.Or it can be used in front and back of the bus, the right side of the road signs up and down, brake, left, right and other information "electronic announcer".In fact, it is much more than that. Since LED on-board screens can travel around the city with mobile vehicles, they can achieve better product promotion and publicity effects than traditional fixed outdoor LED advertising screens such as airports and stations.Many advertising media companies attach importance to this point, have invested in the modification of professional advertising vehicles, the whole body of the car installed with LED on-board display screen, play text, pictures, video and other advertising information, the image of the product through the mobile publicity of the on-board screen, imperceptibly into the hearts of the audience.
, therefore, in the present traditional outdoor led advertising screen due to a lack of innovation, to bring good brand publicity effect of the background, the car led screen has become each big advertisers, even industry insiders predicted that car led screen will directly threaten the outdoor led display "bosses" in the field of advertising position, will be used in outdoor advertisement market is one of the most popular led display products segment, car led screen in the future market is immeasurable.

Led car screen is expected to dominate the automotive display market
In addition to outdoor on-board screens, the use of in-car displays has also increased significantly with the popularity of intelligent Internet of vehicles, new energy vehicles and self-driving cars.According to the latest report, the total number of passenger vehicle displays in 2017 is about 241 million, and it is estimated that the total number of passenger vehicle panels worldwide will grow to 624 million in 2025, with the compound growth rate (CAGR) of 13% from 2017 to 2025.
At present, the mainstream automotive market is still dominated by LCD with high reliability and stability. However, the problem that LCD still needs backlight and cannot be made into a high surface is still criticized by OLED, which is subsequently replaced by OLED. However, the current situation of OLED still needs to be optimized due to the problem of high reliability in automotive.But according to the specifications and performance, Led car is better than that of the LCD screen of the contrast and brightness, can improve product price, although due to the Led car screen process transfer yield is low, it is unable to enter the resolution of the higher order (PPI) area, but if the Led car screen can break through the problem, will likely cut into the application of low resolution (PPI), replace LCD is preferred as the car Led display products.
Features of on-board LED display screen:
1.Cars are always on the move and require high stability and reliability of electronic products.
2.The power supply of the car is powered by batteries. When the car starts, brakes and stops, a high pulse voltage will be generated. If the power system is not good, the display screen will be burnt down.
3.In the north, cars are usually placed outdoors.Winter temperatures may reach to 40 ° C, summer temperatures may reach 60 ° C, this requires a power supply and display components work under wide temperature.
4.Cars are easy to generate static electricity in operation, especially in the autumn electrostatic high voltage can reach thousands of volts, if there is no good anti-static measures, it is easy to damage IC and LED lights.
5.If the brightness of LED screen is not enough, it will not be visible during the day, and the significance of installing LED screen will be lost.If it is too bright, it will affect the driving.
6.LED attenuation features,LED brightness is attenuation, there is a 10-70% attenuation rate in a year, the quality of the half-year brightness will be reduced by half, so that it is unable to see the display content.
7.Others have appearance size and so on.
