We propose methods to control viewing zones of large screen consisted of full-color LED panel. Large parallax barriers have been developed for public 3-D display. By changing pixel arrangements, locations and number of perspectives can be reconstructed. Response of viewer's position caused by a shift of viewing was detected to evaluate the design of stereoscopic viewing zone. Furthermore, an array of slits has been utilized to provide multiple image s depending on viewers' distances for use of digital signage.
