20110037379 | SUBSTRATE FOR ORGANIC LIGHT-EMITTING DEVICE, AND ALSO ORGANIC LIGHT-EMITTING DEVICE INCORPORATING IT - A substrate for an organic light-emitting device, includes a transparent substrate having an optical index n | 02-17-2011 |
20110255168 | GRATING COMPRISING SUB-GRATINGS WITH LIGHT-DIFFUSING PATTERNS - A transparent substrate including at its surface a grating of parallel lines of patterns separated by zones with a refractive index different from that of the patterns, the grating diffusing light and including at least 4 sub-gratings, each sub-grating including plural blocks of identical patterns with a width L, each block including 2 to 10 of the patterns. Centers of gravity of neighboring patterns inside a block are separated by a constant period p, the distance Db between neighboring blocks vary in a non-monotonic manner when passing from one edge of the sub-grating to the other edge of the sub-grating, while being greater than 0 times L and less than 20 times L, and so that it is at least once greater than 1.2 Db | 10-20-2011 |
20110266562 | GLASS SUBSTRATE WITH AN ELECTRODE, ESPECIALLY A SUBSTRATE INTENDED FOR AN ORGANIC LIGHT-EMITTING DIODE DEVICE - A glass substrate includes a first side and a second opposite side, and provided, on its second side, with an electrode which is formed by at least one electrically conductive film, the substrate having, over all of its second side, and through a thickness e extending toward the interior of the substrate in the direction of the first side, a refractive index variation, of the glass, obtained by an ion-exchange treatment, the refractive index at the surface being greater than that of the glass located beyond the thickness e. | 11-03-2011 |
20110294298 | TEXTURED SINGLE CRYSTAL - A method for fabricating a textured single crystal including depositing pads made of metal on a surface of a single crystal. A protective layer is deposited on the pads and on the single crystal between the pads; and etching the surface with a first compound that etches the metal more rapidly than the protective layer is carried out. Processing continues with etching the surface with a second compound that etches the single crystal more rapidly than the protective layer; and etching the surface with a third compound that etches the protective layer more rapidly than the single crystal. The textured substrate may be used for the epitaxial growth of GaN, AlN or III-N compounds (i.e. a nitride of a metal the positive ion of which carries a +3 positive charge) in the context of the fabrication of LEDs, electronic components or solar cells. | 12-01-2011 |
20130299856 | LUMINOUS GLAZING UNIT - A luminous glazing unit including at least one substrate formed by a transparent glazing element; at least one light source; and at least one light extraction device for extracting the light, the extraction device being arranged to create a luminous region, the extraction device being formed by at least one fibrous layer. | 11-14-2013 |
20140232707 | DEVICE FOR GENERATING A DISPLAY IMAGE ON A COMPOSITE GLASS PANE - A device for generating a display image on a composite glass pane is described. The device has: a composite glass pane with a first pane and a second pane, which are connected to each other via an intermediate layer that contains at least one luminescent pigment; a laser projector, which contains at least one laser and an optical system for deflecting a radiation of the laser, the radiation being directed within a region of the composite glass pane; a photodetector, which detects luminescent radiation of the luminescent pigment; and a control unit, which electronically connects the photodetector and the laser projector. | 08-21-2014 |
20140355106 | DEVICE FOR VIEWING AN IMAGE ON A LAMINATED SUBSTRATE - A glazing panel for a display device, includes an external first transparent pane and an internal second transparent pane, each pane including an external face and an internal face, the glass panes being joined together by an interlayer made of a thermoformable material or by a multilayer sheet incorporating such an interlayer; a protective layer made of an opaque material making contact with the internal face of the external first pane; a masking layer made of an opaque material making contact with the internal face of the internal second pane, the masking layer including apertures forming pictograms; and a uniform layer of a material doped with luminescent species chosen because they absorb light radiation produced by the source generating radiation in the UV or IR range, and re-emit light radiation in the visible range, the uniform layer being placed in the glazing panel, between the masking layer and the protective layer. | 12-04-2014 |
20150207105 | SCATTERING CONDUCTIVE SUPPORT FOR OLED DEVICE, AND OLED DEVICE INCORPORATING IT - A scattering conductive support for an organic light-emitting diode device includes, in this order, on a substrate, a scattering layer, a high index layer, a lower electrode with a dielectric underlayer, a dielectric crystalline layer, a single metal layer having an electrical conduction role, which is based on silver, with a thickness of less than 6 nm, and an overlayer. | 07-23-2015 |
