Car LED display
is the use of LED technology, GSM/GPRS technology, low temperature, antistatic technology, anti-jamming technology, vehicle electronic technology such as displayed on the mobile car information products.
Due to its based on a moving bus as the medium, can be circulated widely in many places, a great advertising effect, has been widely accepted, and it is different from ordinary led display in a fixed place to install.
The reason is that car and advertising.
Automotive led display features: 1)
Has high stability and reliability of the car is moving, each time the brake start turning there will be some faint pulling power, thus car LED display high requirement of stability and reliability of electronic products.
Stability of power systems to support the car power source is battery power supply, the same car will lead to short when start, brake and stop supply voltage is not stable, if the power supply system is bad, will burn screens.
Wide working temperature range in the north car generally in outdoor place.
Winter temperatures may reach -
40 ° C, the summer temperatures may reach 60 ° C, this requires a power supply and display components in a wide temperature work.
Good anti-static measures car easy to generate static electricity in the middle of the operation, especially in the autumn electrostatic high pressure can reach thousands of volts, if there is no good anti-static measures, edm is easy to damage to the IC and led lights.
Brightness suitable brightness, LED display if the brightness is not enough, can't see anything in the daytime, lost the installation screen;
If too bright effect.
The LED brightness attenuation which is the common feature of LED products.
LED attenuation characteristic of LED brightness is attenuation, 10 - in the middle of the year
70% decrement, the poor quality of half a year of brightness is reduced by half, which cannot see display content.
Traffic tools such as good generalization the bus can be said to be in all corners of the city, so the effect of the advertising can also affect the whole city, thus bring huge publicity for products services.
