Daum’s interactive HD touchscreens can be found in major subway stations around Seoul, Korea. Since 2010, all Seoul Metro stations feature the world’s largest digital signage service, which are 46″ touchscreen kiosk featuring a combination of advertising, transit information and local area maps. Similar to the digital screens in Kuala Lampur.
What’s interesting about these ones is the three screens:
Small Screen: Used for advertising & ordering items mainly.
Middle Screen: You’ll find local maps, transit information, basketball & sports video replays and tourist information at the touch of a button. It’s interactive, so you can find information you need about the area if you’re lost in Seoul, which is pretty hard to do.
Large Billboard: Mainstream advertising for major movies, car and TV shows I found.
This isn’t your typical digital out of home (dooh) screen and yet it works very well. You’ll also find the standard dooh screens near the end of each platform that tells you when the next train is coming and usually run short video ads as well. In fact I’ve even seen what are maybe 100inch screens at a few station that fun video ads too. Seoul truly is a digital nation with high broadband penetration.
