Publication number: 20170052298Abstract: Systems and methods for ambient-light reduction in display systems with OLED or LCD based displays are disclosed. The base display is interfaced with an ambient-light-reducing (ALR) structure to form the display system. The ALR structure includes an ALR component. The ALR component can be a photochromic component or a fixed neutral-density component. The ALR structure attenuates incoming ambient light as well as outgoing redirected ambient light that is generated within the base display and is then emitted from the display system into the ambient environment. This increases the ambient contrast relative to that of the base display alone.Type: ApplicationFiled: February 12, 2015Publication date: February 23, 2017Applicant: Corning IncorporatedInventors: Jaymin Amin, Raymond Geroe Greene, Tomohiro Ishikawa, Jum Sik Kim, Cheng-Chung Li, Michal Mlejnek, Tina Marie Proulx

Patent number: 9567254Abstract: Chemically strengthened glass articles having at least one deep compressive layer extending from a surface of the article to a depth of layer DOL of about 130 ?m up to about 175 ?m or, alternatively, to a depth of compression (DOC) in a range from about 90 ?m to about 120 ?m within the article. The compressive layer has a stress profile that includes a first substantially linear portion extending from a relatively shallow depth to the DOL or DOC and a second portion extending from the surface to the shallow depth. The second portion is substantially linear at a depth from 0 ?m to 5 ?m and has a steeper slope than that of the first portion of the profile. Methods of achieving such stress profiles are also described.Type: GrantFiled: May 28, 2015Date of Patent: February 14, 2017Assignee: Corning IncorporatedInventors: Jaymin Amin, Benedict Osobomen Egboiyi, Pascale Oram, Jonathan David Pesansky, Kevin Barry Reiman, Rostislav Vatchev Roussev, Vitor Marino Schneider, Brian Paul Strines

Patent number: 9567259Abstract: Described herein are various antimicrobial glass articles that have improved resistance to discoloration when exposed to harsh conditions. The improved antimicrobial glass articles described herein generally include a glass substrate that has a low concentration of nonbridging oxygen atoms, a compressive stress layer and an antimicrobial silver-containing region that each extend inward from a surface of the glass substrate to a specific depth, such that the glass article experiences little-to-no discoloration when exposed to harsh conditions. Methods of making and using the glass articles are also described.Type: GrantFiled: February 10, 2014Date of Patent: February 14, 2017Assignee: Corning IncorporatedInventors: Jaymin Amin, Nicholas Francis Borrelli, Timothy Michael Gross, Odessa Natalie Petzold, Wageesha Senaratne

Publication number: 20170036953Abstract: Chemically strengthened glass articles having at least one deep compressive layer extending from a surface of the article to a depth of at least about 45 ?m within the article are provided. In one embodiment, the compressive stress profile includes a single linear segment extending from the surface to the depth of compression DOC. Alternatively, the compressive stress profile includes two linear portions: the first portion extending from the surface to a relatively shallow depth and having a steep slope; and a second portion extending from the shallow depth to the depth of compression. The strengthened glass has a 60% survival rate when dropped from a height of 80 cm in an inverted ball drop test and an equibiaxial flexural strength of at least 10 kgf as determined by abraded ring-on-ring testing. Methods of achieving such stress profiles are also described.Type: ApplicationFiled: October 24, 2016Publication date: February 9, 2017Inventors: Jaymin Amin, Benedict Osobomen Egboiyi, Jonathan David Pesansky, Kevin Barry Reiman, Rostislav Vatchev Roussev, Brian Paul Strines

Patent number: 9512035Abstract: Described herein are various antimicrobial glass articles that have improved strength and resistance to discoloration. The improved antimicrobial glass articles described herein generally include a glass substrate with a compressive stress layer and an antimicrobial silver-containing region that each extend inward from a surface of the glass substrate to a specific depth.
