Publication number: 20140184035Abstract: Disclosed herein is a television housing and a method of fabricating the same. The television housing includes a stainless steel (SUS) frame and a plastic member adjoining at least one surface of the stainless steel frame. The plastic member includes: a base resin including about 60 wt % to about 95 wt % of (A) a polycarbonate resin and about 5 wt % to about 40 wt % of (B) a rubber-modified aromatic vinyl graft copolymer resin; and about 5 parts by weight to about 25 parts by weight of (C) bondable glass fibers based on about about 100 parts by weight of the base resin including the (A) polycarbonate resin and the (B) rubber-modified aromatic vinyl graft copolymer resin, and has a tensile strength from about 70 MPa to about 130 MPa at about 23° C. The plastic member employs the bondable glass fibers, and thus can prevent whitening due to an ejector pin upon release at high temperature.Type: ApplicationFiled: December 18, 2013Publication date: July 3, 2014Applicant: Cheil Industries Inc.Inventors: Jo Won LEE, Kyuong Sik CHIN, Ji Yea KIM, Sang Ki PARK, Seung Shik SHIN

Publication number: 20130258469Abstract: In order to achieve a high brightness optical source with both spatial size and numeric aperture ideal for fiber coupling, an assembly of multiple individually collimated laser diode chips on submount (COS) are mounted onto a common flat surface and redirected through a series of optical components. This is done in such a manner which allows for active reduction of both overall spot size and numeric aperture. This optical stacking technique achieves a high brightness source which is also suitable for directly coupling into an optical fiber, or can achieve enhanced brightness through the use of existing polarization or wavelength combining schemes prior to fiber optic coupling.Type: ApplicationFiled: March 6, 2013Publication date: October 3, 2013Inventors: Sang-Ki Park, Oscar D. Romero, JR., Trevor Crum, Ed Wolak
