Patent number: 9235046Abstract: This disclosure provides systems, methods and apparatus for providing relatively thinner and less stiff compliant beams for a shutter assembly. A protective coating is deposited and patterned over the shutter assembly before it is released from a sacrificial mold over which the shutter assembly is formed. Because some primary surfaces of the compliant beams are in contact with the sacrificial mold, these primary surfaces are not coated with the protective coating. Therefore, when the shutter assembly is finally released, the resulting compliant beams are relatively thinner and less stiff providing a reduction in an actuation voltage used to operate the shutter assembly. In some instances, the protective coating is patterned into discontinuous segments before release.Type: GrantFiled: January 30, 2013Date of Patent: January 12, 2016Assignee: Pixtronix, Inc.Inventors: Javier Villarreal, Timothy J. Brosnihan, Jasper L. Steyn, Richard S. Payne, Stephen R. Lewis

Patent number: 9225972Abstract: An apparatus for displaying three-dimensional (3D) images includes an array of display elements and a controller. The controller can control a set of display elements in the array to form, at a first time, a first eye image corresponding to input data by causing the light modulators to be driven into a first set of positions. The first eye image includes an angular distribution of light weighted towards a first side of the display. The controller also can control the same set of display elements to form, at a second time, a second eye image corresponding to input data by causing the light modulators to be driven into a second set of positions. The second eye image includes an angular distribution of light weighted towards an opposite side of the display.Type: GrantFiled: August 10, 2012Date of Patent: December 29, 2015Assignee: Pixtronix, Inc.Inventors: Richard S.

Patent number: 8526096Abstract: The invention relates to a spatial light modulator including a substrate having a surface and a modulation assembly coupled to the substrate including a modulation element and a compliant beam. The modulation assembly is configured to limit the bending of the compliant beam towards an opposing surface that would otherwise be caused by inherent stresses within the compliant beam. The invention also relates to a method of manufacturing a spatial light modulator including the steps of forming and releasing a modulation assembly that has a modulation element and a compliant beam formed in a pre-release position to have an intended inherent stress state. As a result of the stress state in the compliant beam, upon release of the compliant beam, the compliant beam bends into a rest position which is different than the pre-release position, where the rest position is based in part on the intended inherent stress state.Type: GrantFiled: February 12, 2009Date of Patent: September 3, 2013Assignee: Pixtronix, Inc.Inventors: Jasper Lodewyk Steyn, Timothy J. Brosnihan, Joyce H. Wu, Mark B. Andersson, Richard S. Payne, John J. Fijol, Roger W. Barton, Nesbitt W. Hagood
