Description

The present invention relates to a display board using LEDs for vehicles.

Currently used company names, advertisements, event guides, and other various display panels for vehicles can be visually checked when they are bright during the day. There was a problem that it was buried in the dark and disappeared.
Therefore, various attempts have been made to make the display board visible at night or the like using LEDs.

For example, Japanese Patent Laid-Open No. 2000-255317 (see Patent Document 1) uses a light emitting diode to display “color” light emission as a display format indicating “passengers are getting on and off”. There is a front cover that consists of a black translucent acrylic board, and a display part with a plurality of light emitting diodes arranged and mounted in a mosaic pattern on the “people” and “bus stop” pattern parts of the printed circuit board. By storing it in a covered case and installing it at the rear of the bus body, at the bus stop, etc., it is possible to recognize that "passengers are getting on and off" with respect to the following vehicles, especially motorbikes and bicycles. A display device for getting on and off a bus vehicle has been proposed which has improved visibility and discrimination for raising safety attention of passengers.

In Japanese Patent Laid-Open No. 2003-122266 (see Patent Document 2), in an information providing service such as advertisement on a moving vehicle body, information data stored in an information providing device is displayed on a paper-like electronic display using GPS or operation. An information providing method for recognizing a place from a system and displaying an image of advertisement information data corresponding to the place on the paper-like electronic display has been proposed.

In Japanese Patent Laid-Open No. 10-49076 (see Patent Document 3), a front display unit using LEDs arranged in a matrix is installed on the upper part of the front window of the bus, and the LED is used on the upper part of the rear window. In addition to installing rear side display units and side display units using LEDs at the top of entrance doors, etc., each display unit is a partition for improving the visibility of display contents from being deteriorated by external light. A bus destination display device has been proposed that includes a board, a filter, and the like on the display surface, and each display unit is controlled by a host controller.

Japanese Patent Application Laid-Open No. 10-188645 (see Patent Document 3) displays a predetermined content such as a type of a train such as a train or a bus, a traveling route, and the like, and includes a display band provided on a vehicle body of the vehicle. There has been proposed a vehicular display device in which the display band has a variable color corresponding to the predetermined content.
