At transfer hubs or commercial district stations (e.g., Dongdaemun Station), LED screens are mostly used for branding, are usually larger in size, and are located close to the exit to maximize exposure
It supports remote WiFi or USB content updates, which is convenient for real-time adjustment of wayfinding signs or advertising screens, and improves operational efficiency
There is a large LED advertising screen at the entrance of the airport railway for commercial promotion, and the location is adjacent to the subway exit passage
For example, through Dayuan Station (Line 4 No. 437) and other stations, LED screens may be deployed near the exit for information release, but the specific configuration needs to be designed in combination with the station traffic flow
The above information is based on the universal design of the LED screen of the subway system in the Seoul metropolitan area, and the actual LED configuration of Exit 1 or 2 of Line 4 varies from station to station, such as Dongdaemun Station focusing on commercial advertisements and Jingdaeparkang Station focusing on wayfinding functions. For precise locations, it is recommended to consult the specific site navigation map
It supports rich media formats such as video and animation, which is more attractive than static lightbox ads, and the brand message is more vivid
Exit 1/2 is usually the main exit with the largest passenger flow, and the LED screen is located in the passage through which passengers must enter and exit the station, with an average daily reach of tens of thousands to hundreds of thousands of people, especially in Dongdaemun Station, Hyehwa Station (Sungkyunkwan University), Myeongdong Station and other business district hub sites, with extremely high exposure efficiency
For example, the LED screen at the exit of Dongdaemun Station directly covers the shopping crowd (young consumers and purchasing groups), while the exit screen at Huihua Station efficiently reaches the college students and realizes vertical scene penetration
The exit screen is seamlessly connected with the commercial body, such as the direct access to the apM mall from Exit 9 of Dongdaemun Station, and the advertisement can guide the consumption behavior of passengers in real time and shorten the conversion path
According to the characteristics of different stations such as University Station Huihua Station and Tourism Station Myeongdong Station, scenario-based content such as campus promotion and duty-free shop promotion can be customized to improve the conversion rate
Compared with traditional media, the unit exposure cost of subway exit LED is significantly lower than that of outdoor large screens in business districts due to its huge passenger flow and repeated exposure
The LED media at the exit of the core station of Line 4 has the four advantages of golden traffic entrance, immersive visual presentation, scene-based reach and flexible delivery, and is a strategic resource for brands to capture the highland of offline traffic in Seoul
