A number of landmark buildings in Korea have recently updated their external appearance using LED lighting, according to the first issue of a new magazine, Korea Sign Industry (KSI), published in English by POPSIGN Co Ltd.
According to KSI, many countries are using "beautiful waves of lights to decorate the nighttime streets of their cities" and several large buildings in Seoul are examples of that trend.
In the 63 Square building, LEDs have been used behind opaque glass panels in the canopy above the store fronts. The canopy contains 1300 high-power RGB LED elements, linked by aluminum channel bars running behind the glass.
Each window becomes a "light pixel", and the giant screen can display a variety of images and light patterns. A similar effect was achieved with the Kuo Hua Insurance Building in Taipei, Taiwan.
