Patent number: 8206793Abstract: An apparatus and method for producing a screen is provided. The method includes propelling a quantity of paint comprising metallic flakes, such as aluminum flakes, toward the screen. The method also includes applying at least one magnetic field in a vicinity of the screen, wherein applying the at least one magnetic field causes at least one metallic flake in the quantity of paint to be oriented relative to the screen in a substantially preferred orientation, thereby producing a screen exhibiting beneficial projection qualities, such as brightness. The magnetic field(s) applied may be unsymmetric in the time domain of, for example, an AC component of the magnetic field.Type: GrantFiled: March 26, 2008Date of Patent: June 26, 2012Assignee: RealD Inc.Inventors: Josh Greer, Mel Siegel, Lenny Lipton, Matt Cowan
