Description

Curved display device {CURVED DISPLAY DEVICE}

The present invention relates to a curved display device.

In general, a roundabout is well-known as one of the planar intersections of roads. Conventionally, confused with a roundabout, it was called a roundabout, but recently it is called a roundabout, and the shape is formed so that a vehicle cannot move in a straight line but moves along the circumference of the traffic island by placing a traffic island in the center where the roads meet.

Accordingly, a vehicle moving along a roundabout cannot run out quickly unlike a crossroad, and there is an advantage in that noise and accidents of the vehicle are reduced.

In addition, the above-described roundabout does not require a traffic light providing a separate signal, and a circular green area can be placed on a traffic island provided in the intersection.

In recent years, in order to efficiently utilize the space occupied by the transport island, facilities for improving urban aesthetics, such as landscape sculptures, urban symbols, and flower beds, as well as green areas, have been installed. Information display devices are installed to induce smooth movement of vehicles, such as borders that divide sidewalks.

However, since the guide display device applied to the roundabout includes a flat panel display having a flat shape, it is difficult to provide traffic information for safe driving to a driver entering several roads.

Accordingly, a standardized guide display device having a curvature similar to that of a traffic island may be installed, but such a standardized guide display device has a limitation in that it is difficult to respond flexibly to the curvature of the traffic island according to changes in size and shape of a roundabout. .
