Publication number: 20130209678Abstract: A method for preparing a porous anti-reflective thin film composed of hollow polymer nano-particles is provided in the following steps: Firstly, an aqueous dispersion having mass percent of 3-7% is prepared using polymer nano-capsules. A thin film comprising polymer nano-capsules is formed by spin coating on one side or both sides of the substrate using a spin coater. The thin film comprising polymer nano-capsules is dried in vacuum at high temperature. After the core materials of the polymer nano-capsules evaporate completely, the polymer nano-capsules turn into hollow polymer nano-particles, and a porous anti-reflective thin film composed of hollow polymer nano-particles is prepared. The thickness and refractive index of the thin film are adjusted conveniently and effectively by changing the concentration of polymer nano-capsules aqueous dispersion and the hollow volume rate of the polymer nano-particles. The thin film has the advantages of high mechanical intensity and abrasion resistance.Type: ApplicationFiled: May 31, 2011Publication date: August 15, 2013Applicant: ZHEJIANG UNIVERSITYInventors: Zhijuan Sun, Xiang Gao, Yingwu Luo

Publication number: 20130003158Abstract: This disclosure provides apparatus, systems and methods for optical decoupling. In one implementation, an optical system includes a substrate transmissive to visible light, a first antireflective structure disposed on a surface of the substrate, a second antireflective structure. The first and second antireflective structures define at least one cavity containing air in between. The optical system further includes a plurality of support posts configured to space the first antireflective structure from the second antireflective structure to define the height of the at least one cavity. A reflective display is disposed on a surface of the second antireflective structure opposite the at least one cavity.Type: ApplicationFiled: June 28, 2011Publication date: January 3, 2013Applicant: QUALCOMM MEMS Technologies, Inc.Inventors: Evgeni Gousev, Russell Wayne Gruhlke
