FIELD: physics. ^ SUBSTANCE: screen has a filled, shape-changeable hollow body in form of a structure made from filled tubes directed in three spatial directions. The structure forms a three-dimensional internal space bounded on all sides and at least one display surface lying on the edge formed by part of the tubes. At least one display surface is made in form of a back projection surface. The internal space forms space which is darkened from the light falling outside and the back projection surface lies on the side of the tubes facing the internal space. ^ EFFECT: higher stability of the screen and quality of image on the said screen. ^ 19 cl, 11 dwg |
