KT considered the special characteristics of the transfer passageway, where people pass through fast, to choose a product that has the widest viewing angle. This is why KT adopted “Samsung SMART Signage.” A total of 134 “Samsung SMART Signages” installed on the four sides of square pillars simultaneously display content, naturally exposing advertisements to passers-by. Plus, the signages are installed 150mm higher than the previous products that were installed at around 1,500mm from the ground, allowing people to look at the whole screen at a glance. Advertisements that play simultaneously on the screen help engage people. “As advertisements are simultaneously played on brighter and clear displays, they always catch my eye on my way to work,” said an office worker who passes through the transfer passageway on her daily commute.
