Abstract :
We propose methods to control viewing zones of a large screen consisting a full-color LED panel. Large parallax barriers have been developed for public 3D displays. By changing pixel arrangements, viewing positions and the number of perspectives are reconfigurable. The response of a viewer´s position caused by a shift of viewing zone was detected to evaluate the design of stereoscopic viewing zone. Furthermore, an array of slits has been utilized to provide different information at multiple viewing distances for digital signage.
