Abstract

Variable transparency screen has been constructed in the form of insulation panel with the driving mechanism inside of it causing the rotation of at least one biaxial oriented movable panel (R) placed between light polarisation panels (P) and (A) by whose rotation by the angle the value of which is less than 460 the change of optical transparency of the screen is achieved (To) the current value of which depends exclusively on the current position of the panel (R). The movement of external ferromagnetic panel (Q) in its housing (W) influenced by permanent magnetic field causes identical movement of the internal ferromagnetic panel (L) in its housing (M) which causes the movement of cable (K) passing through the pipe-like slider (J) which is connected at its ends to the internal ferromagnetic panel (L) and the panel (R), which causes the rotation of the panel (R) and the change of optical transparency of the system To of the surface screen from comparatively full non-transparency Tomin to comparatively maximal transparency Tomax. Variable transparency screen provides the efficient protection of privacy from outside views, protection from temperature, acoustic and environmental mechanical influences, protection from light, particularly sunlight and sun energy, and it is reliable and it could be permanently exploited with the use of standard procedures during manufacturing, assembly, management, operation, maintenance, dismantling and repair works.
