Publication number: 20130208022Abstract: Disclosed is a dual mode function pixel that operates either in a first mode or in a second mode according to the intensity of a projected light to have a high visibility regardless of the intensity of projected light. The dual mode function pixel includes: a first membrane on which a self-luminescent element is formed; one or more membranes formed to surround the first membrane; and a lower layer formed below the first membrane and the one or more membranes to be spaced apart from the first membrane and the one or more membranes. The dual mode function pixel is controlled such that the self-luminescent element is driven either to emit light in a first mode operation or to selectively reflect a projected light by utilizing an interference of light generated between the first to one or more membranes and the lower layer in a second mode operation.Type: ApplicationFiled: November 15, 2012Publication date: August 15, 2013Applicant: Electronics and Telecommunications Research InstituteInventor: Electronics and Telecommunications Research Institute

Patent number: 8508384Abstract: A rearview mirror assembly for a vehicle includes an electro-optic mirror reflective element having a front glass substrate and a rear glass substrate, with no portion of the rear glass substrate extending beyond any portion of the front glass substrate. The reflective element includes a perimeter band disposed around a perimeter border region of a second surface of the front glass substrate. The perimeter band generally conceals the presence of a perimeter seal from view by the driver of the vehicle. A plastic molding may be circumferentially disposed about the circumferential edge of the front glass substrate without overlapping onto the first surface of the front glass substrate. The outermost part of the plastic molding may lack a sharp edge. The plane of the first surface of the front glass substrate may be generally flush with the outermost part of the plastic molding.Type: GrantFiled: November 30, 2012Date of Patent: August 13, 2013Assignee: Donnelly CorporationInventors: John T.

Patent number: 8508831Abstract: A vehicular rearview mirror assembly includes a mirror casing, a reflective element and a mounting assembly for adjustably mounting the mirror assembly at a portion of the equipped vehicle. The reflective element has a front surface and a rear surface and a perimeter edge about its periphery and extending between the front and rear surfaces. The front surface generally faces a driver of the vehicle when the mirror assembly is normally mounted in the equipped vehicle. The rear surface of the reflective element may be attached to an attachment surface of an attachment plate or of the mirror casing to secure the reflective element relative to the mirror casing. The perimeter edge of the reflective element may be exposed and viewable by the driver of the vehicle when the reflective element is attached to the attachment surface and when the mirror assembly is normally mounted in the equipped vehicle.Type: GrantFiled: April 22, 2010Date of Patent: August 13, 2013Assignee: Magna Mirrors of America, Inc.Inventors: Darryl P.
