See-through Information LED is a concept that replaces conventional doors and windows of the subway carriage with a display that hosts information or decorative graphics, while still performing the window/door function. The LEDs can be used to relay important announcements like train delays, emergency situation or for advertisements. Either ways it can be a very helpful alternative to traditional loudspeaker announcements and display ads.

The See-through Information LED for subways is designed by Kim Hye-Jin, Lim Woo-Teik, Seo Heung-Kyo, Jung Dae-Heon, and Jung Young-Wook.
