This is the visual identity system for Huasen Architecture Company’s (HAS) touring exhibitions. Perforated characters on the visual identity system are from the LED indicating system of the exhibitions. Characters on the LED screen are made up of and shown by dots. They can change in any time. No matter characters, symbols or design are expressed through dots. Every exhibition area employs dynamic LED to show its indicating system because we design a new kind of LED character for this visual identity system which will be used on Logo, posters, books, invitations and hand bags. LED character shows texture through punching holes.
