There are several types of portable screens. The classic tripod, seen from classrooms and boardrooms to your Uncle Louie's slides of the old country, is still the most popular screen in rental applications. Durable and portable, the tripod comes in many formats, still a good option for room-to-room use but a bit awkward for traveling.
Collapsible screens, also known as cradle or carriage screens, have surged in popularity in recent years. These can be small tabletop units or full sized, usually made of lighter materials and offering both hard and soft case options, these are the screens of choice for presenters on the move.
Fast fold screens, available in both front and rear projection applications, are common in staging and larger rental applications. Portable, but somewhat cumbersome and time-consuming to set up, these can be "dressed" with drapery kits to enhance their appearance and give a theater like experience.
