摘要： A large-sized transportable projection screen comprising an any-shaped fillable hollow body, which is embodied in the form of a structure consisting of fillable tubes. The aim is to develop a large-sized transportable projection screen exhibiting an increased stability and making it possible to obtain an improved projection at daylight. For this purpose, the structure defines a three-dimensional internal space limited on all sides thereof, wherein the tubes are oriented in three directions in space and the internal space is limited by at least one display surface arranged at the level of an edge formed by a part of tubes.
