At the same time, because it can only reflect light, the visual distance is not far away. In the occasions such as expressways, because the vehicle is traveling at a faster speed, the sign information on the signboard used for road traffic signs or commercial signs can only be seen when the vehicle is approaching. Then the prompting effect is greatly reduced.

Recently, there have been some signs with luminous functions, but most of them use dense LEDs to make the relevant graphic signs luminous. This kind of sign board is connected with simple patterns in series of lamp beads to form a simple dot pattern. Due to the leakage of the lamp beads, the sign board is not obvious in the daytime and has an unattractive image at night, which greatly stimulates the human line of sight. At the same time, it greatly affects the reflective effect of the signboard at night. And after this signboard breaks down, the basic function is lost, and there is a bigger traffic hazard.
