Most of the digital signage is currently operated by private organizations, and it is installed and operated in various spaces such as large buildings, convenience stores, and subways, so many people can easily access it. However, as it is still used as an advertisement media rather than as an alert media, legal provisions for providing disaster warning should be preceded. In particular, it is possible to check the information of the location I selected through the open screen that can be touched, and it is also possible to provide disaster information that can guide the evacuation direction from my location.
Like digital signage, urban electronic display boards and bus information systems do not have a legal basis for providing disaster information, so they need to be resolved quickly. In the case of the bus information system, there are ¡®LED type¡¯ and ¡®LCD type¡¯, but through the LED type, it is possible to provide only in text form. On the other hand, the LCD type can provide multi-media contents in the form of images as well as text.
