Description

[0002] Portable Electronic Display Board [0003]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a mobile electronic signboard, and more particularly, to a mobile electronic signboard capable of providing various road information to a driver in a construction section or the like.

Generally, various kinds of road information such as traffic flow, communication smoothness, delay, congestion, running time of a specific section, rainy weather, freezing, road construction, Variable Message Sign (VMS) is displayed to the driver.

In such a variable information sign, a light emitting diode module for displaying image information in a square electric panel housing is installed in the longitudinal direction and the transverse direction inside the electric panel housing, and one side of the electric panel housing is supported by the installation pole.

However, since these variable information signs are fixed by pillars and the like, it is difficult to use them in a construction section where the position is changed frequently due to the impossibility of movement. In order to solve such a problem, a movable variable information sign which can be moved using a moving means such as a truck or a trailer has appeared.

However, in the case of a conventional movable variable information sign, since the movable variable information sign is installed in a truck or a trailer, there is a problem that a separate installation cost or a large size is required.
