In-vehicle LED display is to use led technology, GSM/GPRS technology, low-temperature technology, anti-static technology, anti-interference technology, in-vehicle electronic technology, etc. to display information products on mobile vehicles. As it is based on the mobile bus as the medium, it can be widely circulated in many places and bring great advertising promotion effect and is widely accepted, it is different from the ordinary LED display installed in fixed places. The reason lies in the vehicle and advertising.
car led display
Features of vehicle-mounted LED display:
High stability and reliability
The car is always moving, every time the brakes start to turn there will be some weak pulling power, thus the car LED display on the stability and reliability of electronic products requirements are very high.
Stable power supply system support
Car power is powered by a battery, the same car in the start, brake, and stop will lead to a short period of unstable power supply voltage, if the power supply system is not good, it will burn the display.
Wide operating temperature range
In the north cars are usually placed outdoors. Winter temperature may reach -40°C, summer temperature may reach 60°C, which requires the power supply and display components to work in a wide temperature.
Good anti-static measures
In the operation of the car is easy to generate static electricity, especially in a fall electrostatic high voltage can reach thousands of volts, if there is no good anti-static measures, electric sparks are easy to damage the IC and LED lights.
Suitable brightness, LED display if the brightness is not enough, you can not see during the day, lost the meaning of the installation of the display; if too bright affect driving.
LED brightness decay
This is a common characteristic of LED products. LED decay characteristics, LED brightness is attenuated, in a year there is a 10-70% decay rate, and poor quality half-year brightness is reduced by half, resulting in the inability to see the display content.
Buses and other means of transportation can be said to be all over the city, so its advertising effect can also affect the whole city, thus bringing great publicity for product services.
