Patent number: 10691010Abstract: A projection screen with micro lenses or micro mirrors for the purpose of suppressing ambient light by means of a patterned layer stack including at least a polarizer and a quarter wave retarder. The projection screen has a surface structure where light from a projector is focussed at positions where the light can escape from the structure and is optionally diffused. The location of the focus positions depends upon the incident angle of the light coming from the projector, and therefore the screen is tailored for a certain projector configuration and projector light direction.Type: GrantFiled: May 22, 2017Date of Patent: June 23, 2020Assignee: BARCO NVInventor: Dirk Maes
