Abstract (en)
A protective screen for a visual display unit (11) has a plate (13) which prevents viewing by persons other than those directly in front of the visual display unit. The plate (13) is fixed in a frame (12) to be positioned in front of the visual display unit (11) by means of tabs of adhesive velcro (27) having a first part (28) which can be fixed to the frame (12) and the second part (29) which can be fixed to the visual display unit (11). The plate (13) comprises a louvre-type film (18) which defines parallel microwindows (22) in order to define a limited viewing angle (23). <IMAGE>
