LED display screens are an indispensable part of our lives. Previously, LED screens were generally placed on some of the more prosperous roads to serve as advertisements, which had a very large limitation on the location of the broadcast. However, after the combination of science and technology and technology, combined with the LED screen and the car, a new advertising method has emerged. LED mobile advertising vehicles are free from the limitations of previous advertising campaigns, can increase the scope of more advertising campaigns and launches, and are also highly praised by those who have received more requests. The LED screen used by LED mobile advertising vehicles is composed of a large number of LED lamp beads, which translates from the meaning of English to light-emitting diodes. It is a solid-state semiconductor original, capable of transforming the band energy into light. To become a light energy, the operating voltage of LED is lower than that of the incandescent lamp used in our daily life. It has a relatively good shock resistance and impact resistance, and its service life is also comparative. long. The LED display of LED mobile advertising vehicles is a combination of many modern advanced technologies, and the displayed resolution and area can all be adjusted according to their own needs, with many high-quality features such as adaptive performance. Good, high brightness, low energy consumption, etc. There are many factors that affect the LED display effect of LED mobile advertising vehicles , such as the fill factor, dot spacing, and brightness. The fill factor of the LED screen can also be called the ratio of the bright area. The ratio of the light emitting area of ​​each pixel to the occupied surface area of ​​the pixel is determined. However, under the condition of the same distance between points, the fill factor is Smaller screens need to be attenuated more than those with large fill factors. At this time, it is necessary to increase the distance viewed.
